Clearblue digital digital test with deadline indicator. Does the electronic test show an ectopic pregnancy?

When planning a pregnancy, spouses need to remember that the most favorable time for conception is the time of ovulation, that is, the moment when, under the influence of hormones, the egg is released from the ovary. This happens approximately 10–17 days before the start of menstruation, and directly depends on the individual characteristics of the cycle.

Home methods are ineffective and inaccurate. For example, measuring basal temperature shows that the egg has already been released. The electronic ovulation test guarantees a clearly understandable and accurate result (99%). A more reliable determination of the right time to conceive a child can only be done with the help of a medical test (blood test, ultrasound).

Operating principle

As ovulation approaches, the body increases production of the hormone estrogen, which stimulates the growth of the endometrium. The cervix opens slightly, cerebral mucus is discharged, creating an optimal environment for sperm.

When estrogen increases, a sharp increase in latinizing hormone (LH) is provoked. Under its influence, the egg is released from the ovary within 24 hours. During the day after this, the probability of fertilization is high.

At the moment when the LH surge occurs, the digital ovulation test detects it and gives a positive result.

What can affect test results

A reusable pregnancy test is not 100% error-proof and sometimes gives a false result.

This may happen if:

Damage to protective packaging.
The presence of weakly concentrated urine.
Taking medications containing hCG.
Hormonal imbalances.
Pathological processes occurring in the kidney area.
Freezing of the embryo.
Delayed ovulation.
Pregnancy occurring outside the uterus.
Expiration date of the test.
Failure to comply with packaging storage conditions.

Terms of use

To obtain reliable data, you must follow all the manufacturer’s recommendations, otherwise the result may not correspond to reality.

Several nuances need to be taken into account. And first of all, you need to know the approximate duration of the cycle (under some factors it may shift slightly). It begins on the first day of menstruation and ends before the next menstruation:

If the cycle lasts up to 22 days, testing is carried out starting from the 5th.
With a duration of 23 – on the 6th.
With a duration of 24 - on the 7th, and then according to a similar pattern.
If its value is 41 days or more, then a reusable ovulation test begins to be used 17 days before the expected start of the next menstruation.
If the duration is different each time, calculate the arithmetic average of the last 3 cycles.

The procedure should be carried out at the same time, optimally from 10 to 20 hours. It is not recommended to use the first morning urine, since it contains a slightly increased concentration of hormones. Before the process, it is not advisable to urinate for 4 hours or drink a lot of liquid.

Taking some medications reduces LH levels, and when the egg matures, the result will be false negative.

Factors influencing the result

In certain cases, an electronic pregnancy test may show a false result, but this does not mean that it is unsuitable or broken.

There are a number of specific reasons that influence interpretation, namely:

Taking hormonal medications that contain chorionic gonadotropin hormone.
Oncological diseases (hormone-producing tumors).
Ovarian cyst, ectopic fertilization or menopause.

The inscription “pregnant” appeared on the display - this is wonderful, you can congratulate your spouse and go for a consultation with your obstetrician-gynecologist.

When the screen display shows “not pregnant,” you shouldn’t be upset right away; the diagnosis may have been carried out early. Wait until the day of your expected period and test again.

If there is already a delay, use a reusable pregnancy test again, preferably after 1-2 days. If the result is negative again, you should consult a gynecologist.

At the moment, a large number of pregnancy test manufacturing companies create high-quality and highly accurate products that provide maximum information regarding pregnancy. One of the latest developments in this segment is reusable pregnancy tests.

The uniqueness of these products speaks for itself; they are easy to use and provide the opportunity to perform diagnostics right at home, which will not be worse than laboratory ones. Despite the fact that such tests have not yet become very popular, everything indicates that soon more and more women around the world will begin to use them.

Application

Using the Cleabl ovulation test is very convenient and simple. But to obtain accurate data, you must completely follow the instructions.

Open the bag and take out a strip of dough.
Align the pink arrows, inserting the module into the case, you should hear a click
Remove the cap, wait for a signal on the display - the device is ready for use.
The procedure is carried out immediately after the icon appears on the screen:
Dip the absorbent tip into a container of urine for 15 seconds, or place it under the stream for 7 seconds. Make sure the body remains dry.
Hold the clearblue digital ovulation test with the sample probe facing down or horizontally for 3 minutes.
After 30 seconds, the display will begin to flash, confirming that a chemical reaction has begun.
Put on the cap.

The result will be in 3 minutes:

Empty circle – no hormone detected, repeat the procedure the next day.
Smiling face - in the next 2 days the probability of pregnancy is maximum. There is no need for further testing.

After some time, the data in the window will disappear and the screen will become blank again.

Using the Clearblue Digital Test System

The Clearblue Digital test is a revolutionary electronic device that allows you to detect not only the pregnancy itself, but also determine the gestational age in embryonic weeks. The accuracy of this device is compared with research using ultrasound equipment, while it is as easy to use as inkjet testers.

Using an electronic device to determine pregnancy is quite simple: remove the packaging, remove the cap, and place the indicator tip lowered down under a stream of urine for 5 seconds. If there is enough urine for testing, the tip will turn pink. If desired, you can use a container with urine.

After painting the indicator pink, put a cap on it and place it on a flat horizontal surface. Wait about three minutes, evaluate the result, which does not need interpretation.

The Digital design is equipped with an electronic sensor on which you can see information about gestation and timing. It works as follows. Like all testers, Digital reacts to human chorionic gonadotropin in the urine of a pregnant woman, which is displayed on the monitor as the presence of pregnancy. But in parallel, the hCG concentration is also calculated, from which the gestational age in weeks is calculated: 1+2, 2+3, 3+4, 4+5, 5+ weeks.

First, a flashing hourglass appears on the monitor - this is the counting system at work. After 3 minutes, “pregnant” is simply written at the top of the display if the result is positive or “not pregnant” if the result is negative, and the dates at the bottom of the display are expressed in numbers. For example, if the monitor displays the number 3+ (3 embryonic weeks), then this corresponds to 4–5 obstetric weeks.

Benefits of Clearblue Digital

accuracy of the fact of pregnancy – 99%;
timing accuracy – 92–96%;
the possibility of early detection of gestation, equivalent to ultrasound detection of pregnancy at 11–12 weeks;
you can test 5 days before your expected period;
ease of use, no special skills required;
can be used without collecting urine - under running water.

Disadvantages of Clearblue Digital

relatively high price - up to 350 rubles.

As a drawback of the Digital tester, some consumers note that results are not saved after 24 hours. But if the fact of fertilization is confirmed, then for most this minus is not a problem.

Errors

The manufacturer monitors the quality of the product. But as a result of incorrect use or improper storage, the procedure will not be possible. This will be indicated by the symbols that appear on the display. Depending on what value appears, you will be able to determine where you made a mistake and do everything right next time.

Explanation of the designations supplied by the device.

Error A - the test was taken out of the container too early, quickly put it back.
Error B - a new strip must be used. It may light up if moisture or urine gets on the absorbent strip before it is inserted into the housing; during the procedure, the test was not in a vertical position; the sampler was directed upward after applying urine; the amount of fluid is insufficient or excessive.
Error C - the instructions indicate that such a violation occurs when the case is damaged as a result of improper storage or contact with urine.
If the screen is blank, a failure has occurred. In this case, before starting the procedure, remove the module by pressing the pink button and insert it back; after applying urine, use a new strip; if the result is the same, the housing must be replaced.

Statistics show that in most cases, malfunctions in the device arise as a result of violation of the instructions or storage conditions.

How accurate are the results of reusable tests - reviews

Currently, the online community widely contains reviews from real people who have tried the tests. The most typical messages are listed below.

Tatyana, 32 years old, Krasnodar:

I felt bad for several days. The thought of pregnancy did not even arise, because I had been treated for infertility for a long time. A friend brought Clear Blue a test to determine the fact of conception and ovulation. Wow, but he soon showed that I would soon become the mother of a beautiful baby.
I didn’t believe it and, on the advice of a friend, double-checked the result, but the answer turned out to be the same. Not feeling my legs under me, I went to the antenatal clinic. Is it true! I will have a baby in 8 months. And I left the device for the future, because someday I might need it again.

Karina, 24 years old, Sergiev Pasad:

My husband and I love to go rafting. Getting ready for my next trip, I decided to go to the doctor to understand why I began to feel unwell. All signs of pregnancy appeared. But after conducting rapid testing, I saw a negative result. I shared my problem with a friend, a pharmacist by profession.
So she said that there are different determination methods. And that reusable devices are more accurate. I thought it was expensive. But the cost turned out to be not as exorbitant as I thought.
I bought this electronic test. Hooray! I am pregnant! But I decided to double-check, since it’s reusable. It becomes scary to think that I could go rafting on mountain rivers in pregnancy. And now I'm expecting a baby.

Svetlana, 27 years old, Moscow:

I felt disgusting several times. I had no idea what caused this condition. I didn’t even think about getting pregnant because I was taking birth control pills. When I came to the pharmacy I learned that there are a large number of different express methods.
I took one at random, its name is Clearblue digital. Wow, this device not only determined that I was pregnant, but also showed how far along I am currently. I was surprised that only in the 4th week I found out that a wonderful baby would soon appear.

pros

Compared to similar tests and the calendar method, digital clearabl has the following advantages:

Provides completely clear and unambiguous information. You don't have to peer at the stripe trying to determine if it's bright enough.
Reliability. You will only get a more accurate result with a medical examination.
Convenience. Can be performed with an irregular cycle.
Speed. In just 3-5 minutes you will get the result.
Individuality. The test takes into account the change in the amount of hormone between two measurements.
Ease of use. The procedure can be carried out in any secluded place, at a convenient time of day.
Versatility. It can be used by all women of childbearing age.
Allows you to plan the gender of the child.

But you should not use the Clearblue digital ovulation test as contraceptive protection to detect the lowest LH levels and prevent conception. After all, sperm remain active for 3–7 days.

Why is there an unreliable result?

If an electronic test is so accurate and reliable, can it be “wrong”? Is there a risk of getting a false positive or false negative result when using the Clia Blue pregnancy test? There is always a possibility of obtaining an unreliable result. In the case of Clearblue models, the error may be due to one of the following reasons:

violation of the rules of the testing procedure;
a number of gynecological pathologies (for example, endometriosis);
a false positive result can be obtained by a woman who was pregnant not long ago, even if the pregnancy did not necessarily end in childbirth;
if the test is performed too early due to irregular periods;
taking hCG-containing drugs for the treatment of infertility;
ectopic pregnancy (this is a special case of pregnancy, so the test will show a positive result, because hormonal fluctuations are provoked by the very presence of a fertilized egg in a woman’s body, and the fact that its localization turned out to be pathological does not affect the hormone level in any way).

Minuses

Like any product, this test has its drawbacks. What you might not like:

The result is visible on the screen for a day, and then disappears. Therefore, saving it as a memory makes no sense.
Gives a false positive result for certain abnormalities in the body.
High price - European quality cannot be cheap.

In addition to the disadvantages, one can also include the fact that in our country, disposable modules are not sold separately.

Kinds. Advantages and disadvantages

The Clearblue company produces several test models: Clearblue Plus , Clearblue COMPACT , Clearblue Easy Digital .

Each of these tests is 99% accurate when done within the time period of the delay. When the test is carried out before the expected first day of the next menstruation, the reliability of the result is lower.

The Clearblue Plus test is the simplest and most convenient to use. It has an ergonomic curved handle and a wide tip, which makes it easier to take a sample for analysis and is the most hygienic.

The performance of the test and the correct sampling can be clearly seen thanks to the color-changing tip; this is the only model with this feature.

There is also a control window in which a vertical stripe appears when the test is carried out correctly, so this device provides double control.

This is an inkjet test with two windows, the results are presented as +-. It is inferior to the Clearblue Easy Digital digital test only in that it does not allow you to determine the gestational age.

Clearblue COMPACT is an easy-to-use, one-step spray test that does not require urine collection in a container, with an absorbent sampler.

It is intended for use from the first day of delay and has only one window where 1 or 2 vertical stripes appear.

There is no control window, the tip is not colored, and the only indication that the test was carried out incorrectly is the absence of stripes in the window.

The Clearblue Easy Digital test is inferior to the Plus model in terms of ergonomics, but has a number of unique features.

The results are given in the form of +/- signs, which eliminates misinterpretation. In addition to the pregnancy indicator, the test has a conception indicator , which allows you to determine the gestational age in weeks from the moment of conception (the period indicated in the antenatal clinic is on average 2 weeks longer).

The results are stored on a digital display for 24 hours. In terms of accuracy in determining the gestational age (92%), this test is not inferior to ultrasound. The main disadvantage of the model is its high price .

False result

Does the test always show the truth? This question worries many girls trying to get pregnant. In some cases they get an erroneous result. It’s bad that a woman doesn’t always realize this. This means that even using Clearblue digital does not provide a 100% guarantee of conception.

It's not just about the quality of the product. The test does not determine ovulation itself, but an increase in the amount of luteinizing hormone. But its jump does not guarantee the maturation of the egg. While increased LH production can occur for many reasons:

The onset of menopause.
For hormonal imbalance.
A sudden change in diet, for example, switching to vegetarianism.
Development of renal failure.
Cancellation of contraceptives.
Ovarian disease.
The onset of pregnancy. The hormones hCG and LH are similar in molecular structure and the test does not differentiate between them. In the case of injections of this drug, it also makes no sense to carry out the procedure.

The opposite precedent may also occur when the test result is negative during ovulation. This happens for the following reasons:

A large amount of liquid drunk the day before artificially decreases the LH concentration.
Frequent urination, the hormone does not have time to accumulate.
Device defective (rare).
Failure to follow instructions during the procedure.

If the test results are negative throughout the entire cycle, there may be a health problem. If your periods are very scanty or too strong, we recommend that you consult a competent doctor.

An ovulation test is a solution for couples who have been trying to conceive a child for a long time. It allows you to determine 2 days when the probability of conception is maximum. You can purchase it freely at a regular pharmacy or on the Internet.

Electronic pregnancy test is an innovative and accurate testing system that determines the presence of a fetus in the early stages. These devices are hypersensitive to the content of the hormone hCG (chorionic gonadotropin), which makes it possible to establish pregnancy 4-5 days before the start of the expected menstruation.

The modern pharmaceutical market offers a huge range of pregnancy tests: from classic strip strips to the latest electronic devices. If the principle of operation of conventional tests is known to women, then digital types should be familiarized with in more detail.

Can the test show an incorrect result?

In most cases, Clearblue tests provide reliable answers. If the device is used correctly, the accuracy of the results will be 99%.

But it may also happen that the test results turn out to be incorrect. If a woman suffers from certain diseases and is undergoing therapy, the test results may be incorrect. When taking hormonal medications (therapeutic pills or medications), there is no guarantee that the test results will be correct.

If a questionable answer arises, the woman is recommended to make an appointment with a gynecologist and undergo diagnostic tests prescribed by the doctor.

Clearblue tests are effective and accurate pregnancy detection devices. Test results are accurate and reliable in 99% of cases.

How to use an electronic pregnancy test

Often, when using a new product for the first time, we are not always competent in its proper use. We often spoil the goods. How to use a modern electronic pregnancy test? Before starting the study, manufacturers recommend reading the instructions for use. The principle of operation of this type of test is similar to the classic one - inkjet. Everything is very simple:

It is necessary to collect urine in a sterile container (for a more accurate result, experts advise conducting the study using morning liquid).
Remove the electronic test from the packaging, remove the tip and immerse it in urine for a few seconds.
Place on a horizontal surface. After 3-5 minutes, the device monitor will activate and display the result.

If you don’t have a clean container at hand, you can experiment without it.
In this case, you need to hold the tip of the device under the stream of urine for a few seconds, and after the above time has elapsed, obtain a conclusion. The electronic test should be used in accordance with the manufacturer's instructions. Incorrect application leads to misinformation.

Kinds

If a woman has doubts about a possible pregnancy, her first desire is to dispel or confirm them. The simplest and fastest way to help in this situation is an express test for a possible pregnancy. Using this device, you can find out whether conception has occurred at home, without visiting a clinic.

The following types of products exist:

The easiest way to determine whether you are pregnant or not is to use a special test strip. Early in the morning, as soon as you get out of bed, you should urinate in a special container or any other container. Then lower the product to the max mark, for no more than 5 seconds. The appearance of a second line next to the control line indicates the presence of pregnancy.
The tablet type of diagnostics has the same principle as the test strip. It is in a special plastic case, has high sensitivity and is able to detect even early pregnancy. To obtain the result, a drop of urine is applied with a pipette into the first window. After some time, information appears in the second (control) window. If pregnancy is present, the transparent reagent will become colored. The result is considered very accurate, its reliability is about 99%.
The inkjet version is much more accurate than the previous two. Its main advantages are the ability to use it at any time of the day or night. Literally from the first days of absence of menstruation, it will show the correct result, which will be visible in 1 minute.
An electronic pregnancy test is considered the most accurate. The result that is reflected is 99% accurate. Activation of the device begins from the moment urine is absorbed. After a few minutes, the result appears, “minus” means no pregnancy, “plus” means confirmation of pregnancy.

Each of the described diagnostic methods indicates the presence of a “pregnancy hormone” in a woman’s body, which begins to be produced immediately after conception and at a certain level, an express test can already diagnose it.

Does the electronic test show an ectopic pregnancy?

Of course, pregnancy planning and the period of conception cause some fears in girls: will everything go according to plan, will the fetus attach to the walls of the uterus, will an ectopic pregnancy occur.
What if pathology occurs? Will tests be able to detect such a pregnancy in time? As gynecologists explain, during the period of fertilization, women produce the hormone hCG. During an ectopic pregnancy, the level of the hormone is much lower than during a healthy one, so classic paper tests do not always show two lines.

Can the electronic test diagnose ectopic pregnancy? Considering the high sensitivity of disposable and reusable digital devices to the hCG hormone, these devices detect both normal and pathological pregnancies in the early stages. Using digital tests, you can not only find out about pregnancy in time, but, in case of serious problems, promptly seek help from specialists.

What can affect test results?

Naturally, there is a small percentage of error in the study in the region of up to 1%. Although modern multi-use tests use the latest technology, even they can show false negative or false positive results.

Test results can be affected by several factors that must be taken into account during analysis:

taking medications with hCG;
violation of storage standards and damage to the integrity of the packaging;
hormonal disbalance;
using the device after the expiration date;
kidney disease;
an attempt at early diagnosis before missed menstruation;
pregnancy pathologies;
delayed ovulation;
low concentration urine.

Despite the fact that everything has its own expiration date and cartridges may also run out sooner or later, but for those girls who want to conceive a child or be absolutely sure of the result, a reusable test will be an excellent option. It is unknown how many one-time tests will have to be done before getting the long-awaited result, but they all cost money, so the reusable option will also be an economical alternative.

Especially for

— Elena Kichak

The ability to determine pregnancy in the first month after conception is a gift for the expectant mother. This is why accurate and convenient electronic pregnancy tests are becoming popular. What is the name of the test indicating the gestational age? How does the ClearBlue test work? How accurate is it? What is his sensitivity? What types are there? When is the best time to take the test? How to use it? Let's figure it out together.

Electronic early pregnancy test

It is possible to verify the alleged pregnancy without visiting a gynecologist only by conducting a special study at home.
Manufacturers of pregnancy detection tests position both modern disposable/reusable electronic tests and classic analogues - strip tests. The only difference is that with the help of digital devices, fertilization is confirmed several days before the start of the planned critical days. Conventional “strips” show this result only from the first days of the delay.

The electronic pre-delay test determines pregnancy in the following percentage: 65% 4 days before the start of your period, 98% one day before your planned period. If the result is negative, the device provides information about favorable days for conception and the ovulation period.

Methods for diagnosing pregnancy

In the first weeks, the uterus practically does not enlarge, and examination in a gynecological chair is not informative.

A delay does not always indicate pregnancy , and if the cycle is irregular, it may not be noticed. Toxicosis and other indirect signs of pregnancy do not appear in everyone and not immediately.

So the most reliable methods for diagnosing pregnancy in the early stages are tests. All of them are designed for rapid urine analysis and react to the hCG hormone contained in the urine of pregnant women.

All existing tests can be divided into:

Test strips (strip tests) are immersed in a container of urine for a short period of time.
Tablet (cassette) with two windows, you need to drop a little urine into the control window, and the result appears in the next one.
Jet tests , which can be used by immersing in collected urine or placing directly under its stream.
Inkjet electronic (digital) , including reusable ones, with replaceable cartridges and a USB port.

Test strips are the simplest and most affordable, tablet and inkjet tests are more expensive, more convenient and reliable, and digital ones are also the most informative.

The Clearblue brand produces several types of pregnancy tests in different price categories and with different capabilities.

General characteristics and operating principle of such tests

Reusable pregnancy tests are based on the latest digital technology. The device looks like a flash drive for a computer with a removable cartridge. Below it is a black and white display.

It contains symbols displaying diagnostic results. If the result is negative, the woman will know which days are suitable for conception.

The device is connected to a computer, on which, based on the test readings, parents decide the issue of determining the period. A woman is pregnant if data on the level of luteinizing hormone and human chorionic gonadotropin appears on the display of a reusable pregnancy test.

The operating principle of the device is simple, similar to an inkjet pregnancy test. A few drops of urine are dropped onto a disposable cartridge, and after some time the result appears on the monitor. It can be negative or positive.

Reviews about the gadget

Reviews of digital tests for determining pregnancy are mostly good. The main advantages that the fairer sex unanimously declare are:

reliability of the result (early diagnosis determines the exact answer, you don’t have to peer at the stripes and suffer: is there a stripe or is it just an illusion);
convenience and simplicity;
duration of saving the result (electronic devices have a memory of 24 hours). However, there are strips that keep the result for years and which can be kept as a keepsake. But you can’t save an electronic test;

Another positive side of electronic devices is additional options. For example, there is an electronic test Clearblue that determines the period in weeks.

Oksana:

-Six months after the birth of my daughter, there was a delay. I got scared and bought a test that promises the correct result even 4 days before my period. Clearblue cost 400 rubles and it showed a minus, that is, there is no pregnancy, which turned out to be true. I liked that the results last for several hours. But I still regretted buying it - it was too expensive, I could have gotten by with a simple strip strip.

Alyona:

-I suspected that I was pregnant, bought a simple test strip, it showed an incomprehensible result - there was a second strip, but it was pale. Then I bought digital Evitest Next. He not only showed the pregnancy, but also named the period - 3 weeks. Then this result was confirmed by ultrasound.

Read a detailed review of the best pregnancy tests from different brands.

Pregnancy is a wonderful condition that you want to know about as soon as possible. Electronic tests will help to reliably establish the birth of a new life and even determine the approximate period in weeks.
