Scraping for enterobiasis: 5 stages of preparation for analysis, 3 methods for studying the material

Procedure: how to take a scraping for enterobiasis in a child

It is not surprising that parents are truly worried when diagnostic testing in the form of scraping is required.
This is truly an important procedure that cannot be avoided. You should immediately warn them that such an event is absolutely painless and safe for the baby. Enterobiasis is usually caused by worms (pinworms) and microscopic roundworms localized in the digestive tract. This is a contagious disease, and a sick child can infect others. In some cases, children are affected by unwashed hands, and both infants and schoolchildren are susceptible to the disease.

Essentially, a scraping is the removal of biological material from around the anus. This is an accurate method that completely determines enterobiasis caused by roundworms, bovine tapeworms, whipworms and other microorganisms.

Scraping is needed to make sure that worms live in the body. These parasites lay eggs in the anus, which is where scrapings are taken. A simple stool analysis is not very informative. You also need to pay attention to the child’s complaints if “there” itches all the time.

Scraping is done for preventive purposes every year, plus routine checks to detect infection. A scraping (or smear) is taken from the child in the morning at the clinic. Make special preparations, don’t take them to the toilet. This way you can get more reliable results. No changes are required to the procedure, except for hygienic requirements. Moreover, the child is required not to be

the procedure is carried out in a medical institution (diagnostic center for children, children's hospital);
The procedure is carried out at home (pharmacy products are used).

Of course, preference is given to specialists. But if necessary, all procedures can be quickly carried out at home, without frightening the baby with a white coat. The main thing is to follow the rules.

In order to carefully scrape, use a pharmaceutical glass slide. You can also purchase special adhesive tape for these purposes at the pharmacy. The procedure is performed as follows:

wash their hands and put on sterile gloves;
peel off the transparent tape from the slide, carefully handling the adhesive part of the material;
gently spread the child’s buttocks and apply adhesive tape to the skin at the anus;
the tape is peeled off quickly but very carefully;
the material is placed on a glass slide, placed in a container and closed;
The material is transported to the laboratory in the morning.

Now it’s clear how scrapings are taken for enterobiasis in a child. This method of collecting material to identify parasites has become widespread today due to its simplicity and effectiveness. At first, hesitant actions are possible, but in the future the procedure will become familiar to both the mother and the child. Do not forget that scraping for preventive purposes will bring more benefits than possible treatment.

Enterobiasis is a helminthic infestation by pinworm eggs, worms that have a pointed end and got their name because of this. The pathology is called the disease of dirty hands, which occurs due to neglect of personal hygiene rules. Children under 12 years of age are most susceptible to infection. The vital activity of helminths in the human body can worsen the digestive process and reduce the immune system, so at the first signs of the disease it is necessary to consult a doctor and undergo appropriate treatment.

Pinworms can be seen in your excrement after defecation, as well as at night when they crawl out of the anus. Also, traces of worms can be detected on underwear and bed.

The material is suitable for analysis for only 8 hours.

Scraping for enterobiasis is a procedure for taking biomaterial around the anus. This analysis allows you to detect the presence of parasites in the rectum with an accuracy of 99%. Most often, the procedure is done according to the Graham method, for 3 days in a row. In this way, you can easily detect various types of worms:

pinworms;
roundworm;
whipworms;
wide tapeworms;
pork and bovine tapeworms;
schistosomes

To carry out the procedure, a smear from the perianal folds is used using:

cotton swab;
adhesive tape;
wooden spatula.

To obtain reliable results, the patient must follow certain rules for the procedure.

Recovery criteria

You can finally verify the absence of pinworms in the body using the following criteria:

no clinical symptoms (no itching in the perianal area, abdominal pain, moodiness);
General blood test is normal (eosinophils within reference values);
absence of detection of pinworm eggs during three-fold microscopic examination of material from the perianal folds after a 2-week course of anthelmintic therapy.

How to take scrapings from a child at home

In some situations, it is not possible to take the child to a medical facility to have a scraping taken for enterobiasis. In this situation, it is allowed to independently collect biomaterial at home and then submit it to the laboratory for research. In this case, you should follow the same rules as when preparing for a scraping performed in a clinic.

At home, it is most convenient to collect material for research using a special container and a glass slide with adhesive tape.

This container is designed specifically for scraping.

It is necessary to put on disposable gloves, place the child on his side, spread his buttocks with one hand, and with the other take the material, running the applicator over the skin around the anus several times, trying to touch different areas.

Then the instrument must be carefully placed in a container, closed and delivered to a medical facility as quickly as possible. The material can be stored for no more than 2 hours and only at a temperature not higher than 8°C.

The material can be stored for no more than 2 hours and only at a temperature not higher than 8°C.

When using a glass slide with adhesive tape, the following algorithm for taking material must be observed:

Wash your hands with soap and wear gloves.
Place the child on his side or tilt him forward.
Remove the tape from the glass, being careful not to touch the surface of the instrument or the sticky layer of the tape.
Spread the child's buttocks with one hand without touching the anus.
With your other hand, firmly apply the tape to the anus for a few seconds.
Remove the strip from the skin and glue it onto a glass slide.
Send the material to the bacteriological laboratory.

Before the procedure, you need to wash your hands.

To take a smear, you need to remove the tape from the glass, being careful not to touch the surface of the instrument and the sticky layer of the tape.

After taking a smear, you need to send the material to a bacteriological laboratory.

Adhesive tape

In order not to traumatize the baby’s psyche, many parents take scrapings at home. This is not at all difficult, but you still need to adhere to the basic rules. So, let's look at how to take scrapings.

The most commonly used method is adhesive tape or tape, which is simple, easy and convenient. How to do it correctly:

lower the baby's pants and lay him on his left side;
spread the buttocks and glue a pre-prepared piece of tape between the folds, press it well and remove it from the skin;
glue the tape onto the glass and place it in a sterile jar;
When gluing the tape to the glass, you need to make sure that bubbles do not form as a result.

Cotton swab

The scraping algorithm is simple, but you will have to purchase special materials for taking scrapings from the pharmacy. You will need:

a cotton swab (it is longer than a cosmetic one);
glycerol;
small sterile container.

How to do it for children:

in the morning before hygiene procedures, lay the child on his side;
spread the buttocks and run a cotton swab soaked in glycerin along the anal folds, lightly pressing on the skin;
Close the finished material tightly in the container.

The algorithm for collecting material is simple, and all parents can do it at home. After the scraping is done, you need to submit it for analysis to the laboratory within two hours. The analysis is done quickly, and the finished result can be collected the very next day.

Parents often use this method when the child is pathologically afraid of doctors or, as a result, is unable to visit the hospital.

You can take the material:

with a cotton swab lubricated with glycerin;
sticky tape.

In the first situation, the stick is lubricated with glycerin. Next, put it in a container and close it tightly with a lid. The pharmacy sells containers and collection tools.

In the case of adhesive tape, take a piece, stick it to the anal area, wait a few seconds. Remove the tape and stick it on the glass, making sure there are no air bubbles. If you accidentally hit the tip of the stick or the glass, you need to redo the procedure again.

Collecting diagnostic material using anal scraping or using a cotton swab is allowed to be carried out at home.

A scraping for enterobiasis and a smear must be carried out in the morning before hygiene procedures.

Remove the child's pants and panties.
Lay on your side.
Spread your buttocks with your thumb and index finger.
Remove the adhesive tape (2x5 cm in size) from the slide and apply the sticky side to the anal folds for a few seconds.
Remove the tape and stick it without creating bubbles to the slide.
Place the slide in a sterile container.
Send the scraping to the laboratory for enterobiasis.

⁕Before the manipulation, do not go to the toilet.

⁕Adhesive tape and glass slide are purchased at the pharmacy.

⁕Carry out the manipulation with gloves, which are thrown away after the manipulation. Hands are washed thoroughly.

The material must be delivered for research within the first 2 hours, or stored in the refrigerator for no more than 8 hours at a temperature of 80C.

Analysis for enterobiasis is carried out throughout the day. You can apply for results the very next day.

In some cases, even if parasites are present in the intestines, it is not always possible to detect their eggs in the perianal folds. With a small number of female helminths, egg laying does not occur every night. With a single study, the probability of detecting helminth eggs is 50%, with a 3-fold study - 90%, with a five-fold study - 99%.

An analysis for enterobiasis is taken and performed on the referral of a pediatrician or therapist in the laboratories of public health institutions free of charge. In commercial healthcare institutions, analysis is performed upon request. Its cost is 250 - 500 rubles.

The test for enterobiasis is valid for 10 days. For children visiting the pool, the test result for enterobiasis is valid for 3 months, for adults - 6 months. After the study, if necessary, you can obtain a certificate from the therapist about the results of the study. The certificate must have the stamp of the medical institution, a triangular seal and the personal seal of the doctor.

Before scraping for the presence of helminths, you should not wash yourself or visit the toilet. Most often, the procedure is carried out in a medical facility. A smear is taken by a laboratory assistant using a sterile swab wrapped in cotton wool or adhesive tape.

The specialist prepares a container with a screw-on lid into which a long stick is inserted. Cotton wool soaked in glycerin or saline solution is wound around the end of the rod. To complete the procedure, the following order is required:

Opening the container is done carefully, wearing gloves.
The patient bends forward, spreading his buttocks to the sides.
The specialist removes the rod, with the help of which circular movements are made around the anus.
After taking the material, the stick is placed back into the container, tightly closing it with a lid.
The container is immediately sent to the laboratory for testing, since the material is valid for 8 hours.

Additionally, studies of the patient’s stool or blood may be required for a reliable result.

Another method involves using a special adhesive tape, which is separated from the glass. Taking material is no different from the previous method:

The patient spreads his buttocks, leaning forward.
The laboratory assistant presses the tape firmly against the surface of the anus.
After the procedure is completed, the tape is again glued to the glass and sent to the laboratory.

To obtain accurate data, the scraping contents are analyzed on the same day. Most often, a smear is performed in the morning, due to the fact that the female worms lay eggs at night.

Enterobiasis can also be detected by other methods that are used in conjunction with a smear. Such methods are used in case of doubts arising from a negative result for enterobiasis.

The following tests are used:

Stool analysis for worm eggs. The accuracy of this method is lower than that of scraping, but it can help identify various intestinal parasites in their entirety, as well as their larvae and eggs. The examination does not require additional preparation and involves collecting stool in a special container with a screw-on lid. The resulting material should not be stored for more than a few hours.
Enzyme immunoassay of blood is quite expensive, but an effective method, showing high accuracy. The analysis determines not only the stage of infection, the type of parasites, but also their number in the body. Blood is taken from a vein, the result will be ready in a short time.

The attending physician determines which analysis to use.

Indications for analysis

There are different ways to determine the presence of parasites in the body. In addition to scraping, stool or blood is given for analysis.

To obtain the most accurate results, you need to prepare accordingly for collecting biomaterial. To do this, the patient must stop taking medications, especially if we are talking about antiparasitic and antidiarrheal drugs.

A couple of days before submitting the biomaterial, you need to limit the consumption of fatty, spicy, salty and fried foods. Defecation should occur naturally without the use of laxatives.

The stool is placed in a container, and the stool is taken from several places. The collected material should not be stored for more than a day. It is better to place the container in the refrigerator.

Scraping for enterobiasis is done in the following cases:

Suspicion of pinworm infection.
Before the child arrives at school or kindergarten.
Help for the pool.
Registration of a voucher to a camp or sanatorium.

To ensure accurate results, you need to prepare before taking the test:

Do not take strong medications (especially antibiotics).
The day before the test, do not eat fried or fatty foods.
On the day of delivery of the material, you cannot wash your child before the smear.

The doctor issues a referral for analysis. In the laboratory, after explaining the course of the future procedure, the child is placed on his side. The nurse spreads the buttocks and scrapes the anus and its folds with a glycerin-soaked swab or cotton swab. Then the material is placed in a test tube, the name is written down and sent to the laboratory.

The execution algorithm is very similar to the previous one. The difference is that instead of a cotton swab, adhesive tape is used. When performing the analysis, the tape is glued to the folds around the outlet for a couple of seconds. After removal, it is glued onto a glass slide. The material is then sent to the laboratory, where a laboratory technician examines it under a microscope for the presence of parasite eggs.

Eyesticks are glass spatulas with one flared edge. During analysis, the extended end of the stick is immersed in special glue and allowed to dry a little. After drying, a film is formed, the stick is applied to the anus and folds around it. Then the spatula is placed in a special test tube and taken for examination.

Subungual scraping

Worm eggs can be detected during examination using subungual scraping in kindergarten. The nurse scrapes under the child's fingernail with a wooden stick. Pinworm eggs spread very quickly. If a child sick with enterobiasis goes to kindergarten, then there is a chance that the entire group will become infected. The remaining children also need to be examined. If the examination shows more than 15% infection, then all children are sent for treatment.

Most often, analysis is carried out using adhesive tape and a cotton swab.

For children of any age, such laboratory research is always psychological trauma and internal fear of the unknown. However, adults should clearly understand how important it is to perform the test correctly and not get a false positive result. Therefore, it is necessary to mentally prepare the little patient in advance so that he is not afraid and relaxes.

So, if an analysis is taken for enterobiasis in children, the first thing the child needs to do is lower his clothes and underwear and relax his buttocks. To alleviate such an unpleasant moment, the doctor can use glycerin. Afterwards, all he has to do is collect the material from the surface of the anus and place it in a special container with a sticker for further examination under a microscope.

A flush for enterobiasis must be performed if the patient has an itchy perineum, allergic reactions occur, and intestinal dysfunction with a sharp loosening of stools is observed. Since eggworms do not pass into the feces, the anus must be examined for examination. If it is necessary for a child to be tested for enterobiasis, the sequence of actions is as follows:

Relax your buttocks, as the scraping is not painful at all.
Moisten a cotton swab with saline solution and glycerin.
Using the rod, treat the anus and folds of the anus.
Place it in a special container and seal it tightly for further research.

At home, these manipulations are carried out according to the same principle. In order for laboratory testing for enterobiasis to be performed correctly, it is necessary to prepare a sterile container, adhesive tape and glass in advance. To further conduct the in vitro test, the following sequence of actions is required on the part of adult parents:

Before taking a scraping from a child, do not wash, perform the procedure in the morning - immediately after waking up.
Take the scraping as described above, then dip the cotton swab into a sterile container and close it tightly.
Store biological material after scraping in the refrigerator, but in order to determine the result correctly, do not hesitate to visit the laboratory.

The results of the scraping will be known the next day. If pinworms were not detected in the body, the result will be negative. Ideally, parasites will not be present in the analyzes at all. If the result is positive, then the breakdown of the tests is as follows:

one “ ” sign means that a small number of larvae have been identified, the degree of infection is characterized as mild;

“ ” is the average degree of invasion, it means that several eggs were detected in the analysis;

“ ” - high degree of infection, quite a lot of worms were found.

If the results are positive, the test will need to be repeated two or three more times to determine the degree of infection.

A positive result indicates that treatment should be started immediately. The disease is treated at home; there is no need for hospitalization. Getting rid of enterobiasis is quite simple. But preventive measures should be taken to prevent re-infection. Cleaning is required daily. Every other day, change the bed linen, wash it thoroughly and iron it several times.

Correct actions by parents will allow you to quickly cope with the disease and prevent re-infection.

Currently, there are several methods for identifying helminths. The most common of them is the Graham method. The examination of biological material for this test is carried out three times. This study makes it possible to identify not only pinworms, but also roundworms, whipworms, broad tapeworms, bovine and pork tapeworms, schistosomes and other parasites. This method has been used in children's practice for quite a long time.

Biological material can be collected in different ways. Most often, a special adhesive tape is used for this. It helps to “collect” all the helminth eggs present on the skin, and in some situations even the remains of the parasites’ bodies. You can also use a cotton swab or wooden spatula to collect the material.

As a rule, material collection is carried out in laboratory conditions. However, you can assemble it yourself at home. In this case, the main thing is to follow the basic rules for collecting material. Often parents cannot collect biological material in a high-quality manner and deliver it for research correctly, so the collection is carried out in a special bacteriological laboratory.

Before the procedure, you should definitely prepare your baby. This is especially important to do if the child is already a teenager. Explain to him that this is not painful at all and is necessary for the disease to go away. A child who tends to show quite strong emotions should turn research into an exciting game. Doctors recommend telling your child a story about how he is a future cosmonaut and needs to take this test before flying on a spaceship.

To collect material in the laboratory from children, laboratory assistants usually use cotton swabs. In some cases, this procedure may be unpleasant, but if the child is properly prepared, it will not cause much distress to the child.

To collect biological material using a cotton swab, laboratory assistants use a certain algorithm. The cotton wool on the tip of the stick is usually pre-moistened with glycerin or ordinary saline solution. This helps not only to correctly collect the material, but also not to cause pain to the child.

Typically, the procedure for collecting biomaterial consists of several stages:

The laboratory assistant opens the container wearing sterile gloves.
The subject leans forward slightly and spreads his buttocks. The mother helps the small child with this. It is important to note that the presence of mommy with the baby helps him feel more calm. Older children and adolescents undergo this study on their own.
The laboratory technician takes out the rod and carefully inserts it into the anal area in a circular motion. This technique allows you to obtain a sufficient amount of biological material for future analysis. During the collection of material, the child should not feel pain. He usually feels only slight discomfort. After collecting the material, a small amount of feces usually remains on the cotton swab, which may also contain both remnants of helminths and their eggs.
After collecting the material, the laboratory assistant places the rod in the container and tightly closes the lid.
The final stage of the procedure is sending the material to the bacteriological laboratory. It is there that research will be carried out to identify pinworm eggs. It is important to note that the collected material will be suitable for analysis within 8 hours. In order to obtain a fairly reliable result, it is stored in a refrigerator.

The test should be taken after preliminary preparation. For this study it is quite simple. It is important to note that preparation should still be carried out, as this will help achieve a more accurate result. The psychological attitude is also very important. It helps to avoid a hysterical attack or severe fear in a child during the procedure for collecting material.

Sometimes parents independently discover signs of enterobiasis in their baby. More often this occurs in infants and very young children. During daily hygiene procedures, mommy may discover helminths or pay attention to severe irritation and redness of the anogenital area. Normally, the mucous membranes and skin in this area should be pale pink. Any inflammation, and especially signs of scratching, should be a reason to consult a doctor.

In what cases is scraping necessary?

The analysis is carried out not only if there is a suspicion of the presence of worms in the child’s body. A certificate of absence of enterobiasis is also required in other cases.

Indications for taking scrapings for enterobiasis:

The presence of symptoms confirming pinworm infection.
Without exception, all children over 1 year of age are analyzed at least once a year. It is carried out in a clinic at the place of residence, or during a mass examination of children in kindergarten.
The scraping result is required upon admission to a preschool, school, or before going to a camp or sanatorium.
The analysis is taken from all children admitted to the hospital for treatment.
If the child has been in contact with another person who has already been diagnosed with the disease.

Infancy also does not exclude a child from being affected by pinworms. The presence of worms in children under one year of age is explained by the fact that they are just beginning to explore the world, they put everything in their mouth, crawl on the floor, can touch a dirty stroller, and infection occurs. A baby can also become infected from contact with an adult. Testing is prescribed for infants after consultation with a doctor.

A child should be scraped for pinworm eggs in the following cases:

before entering kindergarten, school, or going to camp;
before starting hospital treatment;
after contact with a person infected with pinworms;
if symptoms occur that indicate the possible development of a parasitic disease (itching in the anal area, digestive disorders, fatigue, headaches, restless sleep, etc.).

A child should be scraped for pinworm eggs after contact with a person infected with pinworms.

Also, it is mandatory to conduct a study once a year among children over 12 months.

Indications for scraping for enterobiasis are the patient's complaints of discomfort in the anus. Most often these include:

itching, irritation;
inflammation and redness;
candidiasis in women;
urethritis;
vulvovaginitis in girls;
flatulence;
stool disorder.

Sometimes prolonged helminthic infestation can provoke serious pathologies in the body, expressed as:

in increased gas formation;
in changes in intestinal microflora;
in the deterioration of the digestive system;
poor digestion of food;
in skin rashes;
in intestinal disorders;
in long-term headaches;
in deterioration of general health;
in sleep disturbance.

Most often, children affected by worms have difficulty falling asleep and are often capricious.

Testing for enterobiasis using a smear is a mandatory procedure for children attending children's institutions for the first time - school or kindergarten. Also, scrapings are taken from persons entering inpatient treatment, when visiting a swimming pool, entering work in child care institutions, catering and trade. Children undergo annual examinations before going to camp.

What to do if you find pinworm eggs?

If the result is positive, the patient is referred to a doctor to prescribe appropriate therapy.

If there is one patient in the family, the invasion is often transmitted to other household members. Therefore, medications prescribed by a doctor should be taken by all family members. It is worth paying attention to prevention methods:

observe the rules of hygiene and especially control hand washing in children;
ensure the necessary frequency of changing linen and ironing;
stop children from shoving their hands and toys into their mouths;
carry out wet cleaning of premises.

Timely detection and treatment of enterobiasis allows you to avoid the development of serious complications.

Preparing for diagnosis

In addition to the scraping, the baby may be given a blood and stool test. In these cases, children are no longer given any medications; they are also not recommended to eat fried and fatty foods, seasonings and salty foods. In this case, do not use laxatives so that bowel movements occur naturally. You can store feces in a glass container for no more than 24 hours in the refrigerator.

Parents, knowing how scrapings are taken for enterobiasis from a child, should be prepared for the fact that children may react very negatively to the upcoming intervention, so it is important to prepare them for the procedure mentally, explaining in simple, accessible words that without this the disease will not go away.

Otherwise, no serious preparation for the event is required, there are only a few medical recommendations:

It is better to collect a biosample in the morning, after the baby has woken up;
scraping should not be done directly after defecation;
Before the procedure, you should not wash the child, since in this case the helminth eggs can be washed off.

You can take a smear for enterobiasis in a medical laboratory, but also at home, in advance, by asking a specialist for a referral.

Other methods for detecting helminths that cause enterobiasis include stool examination and blood testing for the presence of antibodies to parasitic pathogens. Stool analysis is considered the least informative, since only adult pinworms can be found in feces.

The most reliable diagnosis of the disease is blood. This method makes it possible to almost accurately detect helminthic infestation at any stage of its development due to the fact that the immune system of an infected child produces antibodies to helminths already in the early stages of the disease.

It is necessary to understand that correct test results for enterobiasis depend on proper preparation for scraping. Therefore, before the procedure, it is necessary to exclude hygienic treatment of the anus: this way you can wash off helminth eggs. Also, before the study, you should not visit the toilet “too much”.

Before donating blood for helminthiasis, you must refrain from eating until the test is performed, as well as from drinking, medications that significantly affect health, alcoholic beverages, fatty, fried foods.

The material obtained as a result of scraping is placed in a clean container and sent to a medical facility no more than 8 hours after the test.

Before getting tested for enterobiasis, it is important to prepare. It is quite easy to do this in the laboratory conditions of a clinic, but from a psychological point of view it is not entirely convenient. As a rule, many parents try to prepare their child for the test on their own.

There are several rules that must be followed.

Scraping for enterobiasis in children is carried out in the morning. Before this, you cannot do any hygiene procedures. It is not recommended to wash yourself, as this will compromise the reliability of the results.
Also, analysis for the presence of parasites is not taken after defecation. This also does not give reliable results, and everything will need to be postponed to the next day.

If the test is taken at home, the smears must be delivered to the clinic as quickly as possible - the reliability of the result depends on this. But if this is not possible, temporary storage of the analysis is allowed.

To do this, place the jar with the smear in the refrigerator for some time. The temperature should not exceed 8° C. Storage time requires no more than 8 hours.

After how many days the result

Sometimes it is possible to obtain analysis results immediately if the laboratory technician has the ability to quickly evaluate the submitted material. Clinics usually provide test results the next day. You should not submit the scraping in advance, as it is considered valid for 10 days.

If the test is negative, but the suspicion of the presence of worms remains, it is better to take scrapings three times. Such an examination is much more informative and helps to identify pinworms in 90% of cases.

If a child has parasites (pinworms), the doctor makes a diagnosis of enterobiasis. This disease is quite common today. The cause of the disease is pinworms - nematode worms. Actively developing, they can reach up to a centimeter in length. The favorite habitat of pinworms is the intestines. If treatment is not carried out in a timely manner, this can lead to infection of the body as a whole. At the same time, pinworms are able to move along it, reaching not only the gastrointestinal tract, but also the lungs and even the brain.

Parasites can feel at ease in a child’s body for a long time, because their presence cannot be detected immediately. At first, the child does not experience serious problems, nothing particularly hurts him. There seem to be no obvious symptoms of the disease. Unpleasant sensations may appear in the anus, especially at night. This is the first sign to determine pinworm infestation in a child.

Having noticed the characteristic symptoms in the child, parents should consult a doctor as soon as possible and undergo tests. Only after this will it be possible to confirm the presence of parasites in the baby’s body. The main method of research here remains scraping for enterobiasis in a child. The scraping can be done in a regular clinic and quickly obtain a reliable result.

Normally, the analysis should not contain traces of any parasites. Due to the fact that pinworms often change generations and lay eggs at certain intervals, to obtain correct data you should be tested 3 times, with an interval of 1-3 days. Most often, a positive analysis is noted as follows:

Low degree of invasion. When single worm larvae are detected, the result is indicated by the sign.
In a moderate degree of infection, the scraping contains several parasite eggs. This result is marked .
A high degree of invasiveness is established when a large number of worms are detected and marked.

A positive result requires mandatory therapy, which most often has a favorable outcome.

A negative test for the detection of intestinal parasites may occur in the absence of worms. A false negative result occurs with a single sample of biomaterial and occurs in approximately 50% of cases. Sometimes the immune system suppresses the vital activity of worms, and their presence can only be judged by the local symptoms that arise.

Scraping from the perianal area for helminthic infestation is a simple manipulation, the result of which will be ready depending on the workload of the laboratory. Most often, the biomaterial is examined on the same day and the results are sent to the attending physician the next day.

Sometimes the material is studied later than 8 hours later. In this case, the container with the contents is placed in the refrigerator for no more than a day.

You can find out the result for enterobiasis within 2-3 days after the test. However, a specialist may prescribe a repetition of the procedure in order to obtain accurate data or if there is doubt about the result.

If the patient receives a negative result against the background of clinical symptoms, the diagnosis should be repeated several more times. When analyzed three times, 1 day apart, the reliability reaches 99%.

When tested only once, the result can be positive in approximately 50% of cases. If the result is negative and symptoms are present, the doctor may prescribe therapy without laboratory confirmation.

Examination of stool for the presence of helminth eggs also has a low accuracy of the result, therefore it is rather an auxiliary method of identifying parasites, carried out in conjunction with scraping. With enzyme immunoassay of blood, the reliability of the analysis is almost 100%.

The test for enterobiasis is valid for 10 days.
