How accurate is the test?
In addition to choosing the right time for a pregnancy test, remember that its accuracy depends on how closely you follow the instructions in the instructions, when you ovulated (and therefore conceived), and how sensitive it is. When used correctly, the reliability is 99%.
Keep in mind that if your urine test shows a positive result, you will need to confirm it with a blood test at a clinic or laboratory. If you get a negative answer, but still have all the symptoms of pregnancy, you may also need to donate blood to rule out problems.
To improve literacy
To always write correctly, you should know the rule and understand the difference between an adverb and a pronoun. This means that it is important to identify the dependent word and be able to ask the correct questions. A reminder will help with this:
- Adverbs denote a characteristic of an object or action. They explain the verb or adjective and do without dependent words.
- Numerals are attached to nouns that denote dimension or quantity. They answer the question: what number?
- The word how many when used as a numeral is written separately, when used as an adverb it is written together. Its correct spelling depends on the context of the word in the sentence. You can check your grammar by asking the questions above.
- How often is a comma placed before an adverb? However, the word usually appears at the beginning of the sentence, and there are no problems with punctuation.
A coronavirus patient gave advice: COVID-19 disguises itself as anything
I have made a selection of advice from a sick person so that you do not step on my rake and do not waste the precious time needed for quick diagnosis and treatment.
Tip 1: Your throat is “covered” - be wary.
This is exactly how it all started for us. There was no sore throat. Rather, it is a feeling familiar to all fans of live rock concerts or karaoke. When you sing as hard as you can, but then your vocal cords refuse to cooperate. The throat seems to be blocked, as if something is in the way. I constantly want to cough and clear my throat. This symptom is very similar to the sensations of pharyngitis. But pain, I repeat, may be completely absent.
Tip 2: Don’t rush to take antiviral medications.
I am generally opposed to all kinds of “bullshit” drugs. But here the doctors who treat patients with COVID-19 themselves say: the coronavirus didn’t care about all kinds of drugs with the prefix “flu”. So don't overload your body with useless medications. And at the same time, don’t unload your wallet. No self-medication!
Tip 3: Control the temperature.
The dynamics I observed are broadly similar to those described by patients and doctors around the world, from China to Italy to the United States. The coronavirus starts with low-grade numbers, 37 – 37.3. At this stage, the ambulance will not go to you, even if you sob into the phone. At the most, they will advise you to drink motherwort. So make a strong friendship with a thermometer and measure your temperature several times a day. If the temperature does not subside for several days, call 103 and insist on a team leaving.
Tip 4: Call a doctor at home, even if you don’t have a runny nose or a sore throat, but there are unusual symptoms: severe headache, diarrhea, muscle aches
This has been heard from everyone for a month now: at the first symptoms of ARVI, stay home and call a doctor. The problem is that “corona” likes to disguise itself as anything, just not the seasonal ARVI that is familiar to us all. What, for example, we didn’t have: sore throat, runny nose, stinging eyes and watery eyes. Simply put, nothing that people associate with respiratory diseases. Here’s what happened: a severe headache (I was afraid it was a stroke), severe muscle pain (not relieved by painkillers and ointments), upset stomach.
Tip 5: Most likely, at first you will be given any other diagnosis, but not COVID-19. It's too early to relax.
At first, coronavirus (until pneumonia sets in) is very difficult to distinguish from other viral diseases. Hence the leapfrog with diagnoses. We were initially diagnosed with an enterovirus infection because one of the first symptoms was digestive problems and abdominal pain. Only the treatment prescribed for the “enterovirus” did not help at all. If the prescribed therapy does not bring relief, call the doctor again.
Tip 6: Don't count on the tests being accurate. If you have symptoms, act as if you have coronavirus: self-isolate.
Actually, don’t count on tests at all. Dry statistics: we had smears done three times on an outpatient basis. Of these, three tests were lost. The diagnosis was confirmed only in the hospital based on the clinical picture. Doctors themselves talk about the high percentage of errors and false negative tests. So if you have a fever, a feeling of a stuffy throat or chest, and other unpleasant symptoms, and the tests are not ready yet or have been lost, this is not a reason to walk down the street. For at least two weeks from the moment symptoms appear, live by the rule: “if you haven’t been arrested, this does not mean that you are not a criminal.”
Tip 7: The disappearance of odors is a sure sign of Covid, but not a reason to panic.
When you realize that everything smells the same - no way - a big shiver begins to strike. Chinese doctors say this is a clear symptom of coronavirus. By the way, it may not come at the very beginning of the disease. Our smells disappeared on the fifth day. They also return differently for everyone. First, base notes appear: for example, perfume begins to smell of alcohol, and coffee begins to smell of bitterness. Then gradually the aromas acquire additional accents and are revealed to their fullest. The process is frightening and fascinating at the same time. But this is just a reason to wait it out calmly. You shouldn’t spray all the drops you can get your hands on in your nose. This is useless and harmful to the nasal mucosa.
Tip 8: If you get sick at the dacha, run to Moscow.
Many Muscovites fled to their dachas. However, this is also not a panacea. Doctors themselves say that you can catch coronavirus anywhere. You can also go to a rural grocery store. Unfortunately, outside the capital, as I myself have seen from personal experience, there are different approaches to diagnosis. Tests are only taken if you have been in contact with people who have returned from abroad or with a person confirmed to have COVID-19. Just on the way you don’t need to contact anyone, stop at shops and even, if possible, gas stations. If you need to fill the tank full, get out of the car only wearing a mask. No mask - scarf over half the face and away you go.
Tip 9: If the temperature does not subside for several days, be sure to do a CT scan.
Even if your local therapist assures you that he doesn’t hear anything suspicious in your lungs. This is another mystery of the coronavirus: the pneumonia it causes is heard poorly or not heard at all. There is no need to self-soothe, it can be fatal. If you have a fever, if you feel unwell, run to a tomography scan.
Types of express tests
They choose a home test for HIV, taking into account which generation they belong to - the third or fourth. It is necessary to decide which biomaterial is more convenient to use for research – blood or saliva. They also take into account the cost of the set, because not everyone can pay 500 or 1000 rubles for it. The instructions for use, which are included with any rapid HIV test, will help you figure out how to use the device. In this case, the help of a qualified physician is not required, however, in a medical institution, doctors can use a similar kit to quickly check the patient.
Spelling
According to the rules of the Russian language, the correct spelling of this word depends on the context. Therefore, in some cases it is appropriate to write this word together, and in others - separately. Let's examine these cases in more detail.
Use of the word how much
To what extent is it written together when it is an adverb. This adverb is formed by using the prefix “on” added to another adverb how many. In this case, how much can be replaced without losing the original meaning with the words: how, to what extent, to what extent.
There is another construction in spelling, where the word must be written together: “as much as... as much...” This structure of lexemes compares comparable concepts. For example: The book was as expensive as it was interesting and useful in learning. Such variants of sentences occur in speech, but not very often.
Example sentences
- As far as I know my native language, it is customary to almost always write adverbs together.
- Anastasia stated that as far as she knows, Nikolai Sergeevich prefers to get up early in order to have time to do more things in a day.
- How much or how much - that is the question!
- Analyze a chemical compound obtained in our laboratory as accurately as possible!
- To what extent would such an act be justified?
Use of words how much
Now let's look at the spelling of the words "how much". It is customary to write such a combination separately when it is an interrogative construction that implies an answer in the form of a numeral. It is easy to see that in the form “by how much” the preposition “on” is used with a question word. And in the context of the sentence, a dependent word is used, to which the interrogative refers.
Let us explain this with an example. How many centimeters is Vasya taller than Petya? Here a question is asked in which the lexeme centimeters is present, depending on the question word how many. Therefore, here it is customary to write the phrase we are considering separately.
Example sentences
- How many more pages is the novel “War and Peace” than the novel “Dubrovsky”?
- How? Has Konstantin already left? How many days did he go to the sanatorium?
- How many meters can sea waves rise during a storm?
- My father always told me: “No matter how many parts you divide zero into, in the end there will still be zero!”
- How many rooms are you planning to build a house for?
When should I take the test after the delay? Is it possible to do it before the expected onset of menstruation?
Since there are many pregnancy tests available, keep in mind that sensitivity is key to successful use. Pay attention to what is written on the packaging. Most of them show results within a few days or a week after the delay, but some claim that you can find out about pregnancy five days before, although they cannot give guarantees in this case. Accuracy scores increase as you get closer to the day your period is due.
Waiting for a pregnancy test can be stressful. Many women begin to feel all the symptoms before their period begins, and if they track ovulation, they know that it may take several weeks to get a definitive answer. If you want to take a pregnancy test very early, you should choose a more expensive and more sensitive one, and also purchase additional samples, since the first ones may be negative.
I don't recognize you in makeup!
Why do the latest tests get it wrong so often?
“There are different tests - good and bad,” says Genotek CEO Valery Ilyinsky. — Testing accuracy and sensitivity is required to obtain registration in Russia. If a test gives 30% false positive results, it will not be able to obtain a registration certificate from Roszdravnadzor.”
Maybe the virus has mutated so much that tests can no longer recognize it?
“The likelihood of this exists, but tests are initially developed in such a way as to detect the most conservative (stable) regions in the virus genome,” explains Valery Ilyinsky. — Mutations in conservative regions occur extremely rarely or do not occur at all. However, in the case of coronavirus, hundreds of genomes are now known, analyzed in different countries around the world. The number of new mutations in the coronavirus is small, so I would rate the likelihood that some system is not working well due to a new mutation as zero.”
Is it possible to do without testing at all?
The head of the Ministry of Health, Mikhail Murashko , said that doctors can make a diagnosis of “coronavirus infection” based on the clinical picture, without waiting for laboratory confirmation.
“There is no point in mass testing for coronavirus infection,” says Corresponding Member of the Russian Academy of Sciences, Deputy Director of the Moscow State University Medical Center. Lomonosov Simon Matskeplishvili. — A PCR test shows whether the patient currently has the virus. After 5 minutes, the result may no longer be relevant - a person may become infected upon leaving the clinic. In addition, in medicine there is a principle - any study should be performed if its result leads to a change in treatment tactics. If the patient is treated the same way as before, there is no point in testing.
ImmunoChrome-antiHIV
This diagnostic kit is of the third generation, that is, the result is reliable no less than 12 weeks after questionable contact. The product is made in Russia, brand “Be Sure”. Anti HIV immunochrome is designed for taking blood samples for HIV 1 and 2, an express kit can be bought in an online pharmacy for 204 rubles. The package includes a diagnostic tablet with Stat-Pak series reagents, a lancet and a disinfectant wipe will have to be purchased separately. It is based on an immunochromic method of analysis, which is based on the reaction of an antibody contained in a biological material with an antigen.
Russian test systems for diagnosing coronavirus are 100 times weaker than European ones
Firstly, in mild cases, no particular treatment is really needed, taking into account the fact that having been ill once, you can easily catch a second one due to an already weakened immune system, this is not chickenpox, only a mentally retarded person can want to wallow in an infectious disease with a mild form. I saw here the TG channel of a woman who had gone, who was broadcasting to a very large audience about how she made her way to the hospital with a scandal, managed to get them admitted, is now lying there taking pictures of the fucking blankets and whining about how bad everything is. Anamnesis - she has had a low-grade fever for three (!) months, every (!) day - 37.5 and she did not care about this before the virus. At the hospital they looked at her, took her temperature, it turned out to be even lower and they said that she had, at most, untreated bronchitis, they wanted to send her home. The little fucker made her way to the infectious diseases department with a scandal, and is lying there. He says that killer doctors don’t want to take most patients to infectious diseases hospitals, not even knowing that we now have infectious diseases divided into those with corona and those with other diseases. 37.5 has nothing to do with either mild form, or severe form, or ordinary pneumonia, or viral pneumonia at all. A serious temperature is considered above 38 at least. Sensitivity has nothing to do with it at the moment - because no one has built curves, the results have not yet been analyzed anywhere, not only in the Russian Federation. There, in addition to the test, they also take a smear upon admission and the test is carried out more than once, until it is positive at the entrance and negative at the exit without treatment, but no one hides the fact that in such a situation it is necessary to say for sure that the tests correctly determine or what exactly No you can not.
When is the best time to take a pregnancy test?
At what time of day is the test most accurate?
At night, most women sleep soundly and do not wake up until the morning. All the urine produced overnight accumulates and becomes quite concentrated. Due to this, it has a higher level of various components and substances, including hCG. This is why the best time to take a pregnancy test is in the morning (after waking up).
How many days after conception can the test be done?
Remember that the test may not show a positive result until your period is expected, or even for several days after that. Although, thanks to very sensitive and more expensive tests, some women can find out that they are pregnant even before the delay, this is also not always possible.
Therefore, to save money, it is better to wait until at least one day has passed after the delay. Since expensive and sensitive tests are only about 60% accurate before the delay (depending on sensitivity and the number of days before the delay). And if the date of your period has already arrived, then a simpler and cheaper one will be enough.
