Electronic test 3 shows. Why is an electronic test better than a regular one?

Content

Whether pregnancy has occurred or not - women often wait for the answer to this question with bated breath. An electronic pregnancy test is a reusable device that accurately provides an answer from the first week of pregnancy. The express device has become part of the home first aid kits of girls all over the world. The test allows you to carry out the analysis at home without waiting for a doctor's visit.

What is an electronic pregnancy test

Primary diagnosis of pregnancy at home is mainly carried out using disposable strips - rapid tests. The result is interpreted depending on the number of lines that appear: one line means pregnancy has not occurred, two indicate conception has taken place. There are difficulties: the second mark is blurred or disappears after some time. There is no exact answer, you have to guess, doubt, repeat the analysis, plan a visit to the doctor. A digital pregnancy test provides early diagnosis, with a correct and unambiguous result.

A highly sensitive electronic device designed to home use, starting from the first week of delay. Three minutes after the analysis, the result is displayed on the analyzer display. IN different models devices, the indicator of conception is the following: the “+” sign, a smiling emoticon, the inscription “Pregnant”. Separate analyzers determine the fact of pregnancy and the duration.

Advantages and disadvantages

Electronic tests have advantages, the main of which is the sensitivity of the device. When used four days before the expected date of menstruation, the accuracy reaches over 50% and increases with each subsequent day. When analyzed on the first day of the delay in the monthly cycle, the accuracy of the method will be 99%. The answer is clear, it is impossible to make a mistake in its interpretation.

The information content of digital devices will pleasantly please you. Express analyzers are produced that show the expected date of conception when pregnancy occurs. The period of embryo formation is displayed in weeks. For repeated use of the device, it is equipped with twenty replaceable cartridges. They change with each use.

The main disadvantage of electronic devices is the price. Customers note that they would like to be able to purchase additional sets of cartridges separately to continue using reusable tests, but this option is not offered. The manufacturer offers twenty replacement cassettes in the kit. The device is designed for twenty-one tests.

Principle of operation

After the fertilized egg attaches to the wall of the uterus, the body produces the hormone human chorionic gonadotropin (hCG). It is present in urine and blood. The principle of operation of devices for determining conception is analysis of the amount of hCG. Inside the electronic test there is an element that is sensitive to an increase in the level of the hCG hormone, detecting a concentration of 10 mIU/ml, which corresponds to 4 days after the embryo is fixed. The norm for non-pregnant women is 5 mIU/ml; conventional strips determine the level from 25 mIU/ml, which corresponds to a period of 2 weeks.

Can a digital pregnancy test be wrong?

The possibility of error is present in research. The accuracy of modern digital tests is above 99%, but they can also give a false positive or false negative result. In the first case, conception did not occur, but the test shows a positive answer. With a false negative, there is a pregnancy, but the test does not confirm it.

Possible causes of testing error:

• using the test after the expiration date;
• damage to the integrity of the packaging, violation of storage standards;
• early diagnosis(before delay);
• delayed ovulation;
• low concentration urine;
• pathology of pregnancy (ectopic, or frozen embryo);
• kidney disease, hormonal imbalances, taking medications with hCG.

Pharmacies now offer a huge selection of various rapid tests for determining pregnancy; they have high sensitivity and good reliability of the result. It is thanks to this variety of assortment that any woman can choose a product by price, type, version or manufacturer. However, the electronic pregnancy test is considered the most popular and accurate. Let’s figure out what its advantages are.

Kinds

If a woman has doubts about a possible pregnancy, her first desire is to dispel or confirm them. The simplest and quick way which will help in this situation is a rapid test for 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:

1. 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.
2. 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%.
3. 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.
4. 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.

Features of digital testing

Electronic pregnancy tests come in a small plastic case with a screen on it. Their price is an order of magnitude higher than conventional test strips, which simply answer “yes” or “no,” however, the advantages are much greater.

TO positive aspects Applications include:

• Good information content, since a pregnancy test before a missed period of 4-5 days is already capable of producing a result. If it is positive, it is possible to determine the approximate time of conception (with an accuracy of several days). This feature of the control test is great for women who have problems with their menstrual cycle, such as irregular start dates and length of periods.
• Testing will help determine optimal time for possible fertilization.
• Among the advantages is that the electronic pregnancy test can be used in any setting. It is compact, well protected and has a beautiful design.
• The accuracy of the results lasts from 5 minutes to 24 hours. This is very convenient compared to other diagnostic methods that are used at home (for example, strips that can change color as they dry).

The use of this express test allows women to make diagnostics at home with an accuracy that is not inferior to that of the laboratory. The most important thing is to correctly evaluate the result obtained. Sometimes women are confused by the too intense color of the test strip. The applied reagent is often mistaken for positive result.

The main disadvantage of digital testing is its high price. However, due to the accuracy and reliability of the results, it is quite popular among women.

Reusable tests

All rapid tests are highly sensitive products high precision. But unfortunately, most of them can only be used once. Latest developments allowed women to be diagnosed using reusable tests.

Today, most women choose the Clearblue electronic pregnancy test, the operating principle of which is practically no different from the inkjet diagnostic option. It has a wide tip and a special handle, which will make the process of collecting material easier for you, as well as ensure sterility and hygiene.

Clearblue - reusable pregnancy tests. The device has 2 windows. One is a control one, where a strip appears if the study was carried out correctly, the other displays the result.

You must bring the receiving end of the electronic device under the stream of urine for literally 3–5 seconds. An hourglass will appear on the display, and it will count down the time. After 3 minutes, either “+” will appear on the screen, which will indicate that fertilization has occurred, or “-”, which will indicate its absence.

Electronic test for possible pregnancy, reusable - the latest digital development, equipped with a special storage device with a disposable removable cartridge. You need to place diagnostic material on it (in our case, urine). The kit contains 20 cartridges, i.e. 20 possible diagnostics.

This device (using a USB cable) can be connected to a computer or tablet to analyze the data in more detail and see the result. A reusable pregnancy test allows you to determine the expected date of birth of your baby. If the result is negative, it can be used to find out the most favorable day for conception and fertilization.

Factors influencing the result

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

There are a number of specific reasons influencing the interpretation, namely:

• Reception hormonal drugs, which include chorionic gonadotropic 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.

Nausea? Dizziness? Weakness and fatigue? - these may be the first symptoms that the body is ready to create new life. But not always! Still, in order to exclude diseases, it is worth checking whether a new addition is brewing in the family.

How do pregnancy tests work?

A pregnancy test is performed by detecting the hormone hCG (human chorionic gonadotropin) in the urine. This hormone is present in both men and women, but when pregnancy occurs, its level quickly increases in the cells that form the placenta and continues to grow throughout the first trimester. It usually takes two weeks after the egg is fertilized.

When to buy a pregnancy test?

The production of hCG begins approximately six days after the birth of life; at least two weeks must pass for a pregnancy test to detect increased hCG level. Therefore, immediately after sexual intercourse you should not run for a test, because it will not give a positive result. Although, for example, an electronic pregnancy test can be done in the early stages, already on the 5th day after sex. However, it is best to wait until your period is missed.

How to test at home?

First, you need to carefully read the instructions for use, because there are different variations of tests. In addition, it is worth paying attention to the expiration date. The details of how a pregnancy test is performed may vary depending on the type of test, but basically it's very simple:

• Before this, you should not drink a lot of liquid, so as not to dilute the hCG level.
• It is advisable, to obtain a more accurate result, to take the first portion of urine after waking up, since the pregnancy hormone will be more concentrated.
• Having collected urine in a glass, depending on the type of test, it is either applied to the test, or the test stick is immersed in the container to the desired level marked on it. Keep the test in your urine for a few seconds.
• It may take 10 minutes for results to appear.

Results: Depending on the test, results appear differently, some test lines have pink color, and some are blue, others display plus signs, but most of the tests are identical.

• One strip - negative
• Two stripes – positive (pregnancy has occurred)

Even if the result is clear. It’s still better to visit a doctor for a blood test for hCG, which will show with 100% accuracy what condition the female body is in.

Types of tests

Depending on the price and desire of the woman, today you can choose how the pregnancy test will be performed. Let's consider the following test options:

• Electronic (digital) pregnancy test. Created for those who do not want to suffer from guessing about their situation. The price of an electronic pregnancy test at pharmacies is higher than other tests, but reviews indicate that it is a worthwhile investment. How does an electronic pregnancy test work? The digital test can be dipped into urine or placed under the stream. The result is displayed on a digital screen after three minutes, where a “plus” or “minus” is displayed, and in some options you can read “pregnant”, not “pregnant”. There are electronic pregnancy tests that indicate your gestational age, such as Clearblue. The accuracy of electronic pregnancy tests is 98 - 99 percent. Manufacturers produce different types electronic pregnancy tests. It can be disposable or reusable. A one-time test is used only once. The clearblue reusable electronic pregnancy test can be used several times by changing the cartridge before each diagnosis. Women often wonder whether the electronic test will show ectopic pregnancy? Given the high sensitivity to the hCG hormone, the electronic test shows an ectopic pregnancy.

Alena: I like that you don’t have to try to make out the lines and wonder if I understood everything correctly. Already on the ninth day after sex, an electronic pregnancy test showed a positive result. Based on reviews, I used the clearblue electronic pregnancy test.

• Jet test. No need to collect urine in a container. The test device allows you to urinate directly on it by simply placing a plastic stick under the stream, making it easy to use. After three minutes, the test will show one pink line - if there is no pregnancy, and two lines - if fertilization has occurred. Known as the most sensitive test (backed scientific research), the creators of such a test claim that within five days after fertilization, you can find out the result.

Alena: With its help, I got a positive result yesterday morning, on the 11th day after ovulation.

Evgeniya: I found out that I was pregnant 10 days after ovulation. On the same day, doctors confirmed this result with a blood test.

• Stripes. A very affordable test option. They are more like litmus paper. Collect the urine in a container and immerse a paper strip in it. Wait up to twenty seconds, then, like other tests, one line will appear or not, depending on whether the pregnancy hormone is elevated. This is not a super sensitive test, but some mothers claim that they received a positive result already on the tenth day after ovulation.
• Tablet test. A plastic stick with two holes, into one of which a couple of drops of morning urine are applied using a special dispenser, and the result is displayed in the second window.
• Extended test. Unlike other tests, it not only shows a positive or negative result for pregnancy, but also actually assesses in what week it develops. Is 99 percent accurate.

Are the results accurate?

Over the past few decades, test kits have become extremely reliable, so that if the result is positive, it almost certainly means pregnancy.

If you have recently had a miscarriage, you need to be careful, since the level of the hCG hormone in the blood is still unstable and it takes some time to return to normal life. It is also possible to have a false positive result if you have taken any fertility drugs containing the hCG hormone or other medications:

• hypnotic;
• diuretics;
• anticonvulsants (used to treat epilepsy and sometimes anxiety);
• tranquilizers;
• promethazine (anti-allergy).

Negative results, however, are less reliable. For example, if the test was carried out at an early stage, before the hormone had risen to the desired level, the test will not give a positive result, even if pregnancy has occurred.

What if the test showed positive, but after some time - negative?

In some cases, a pregnancy test revealed a fertilized egg, which subsequently did not develop. This is the so-called early miscarriage, which is often not even noticed by women, and comes out along with menstrual blood. Such cases are quite common - up to 80% of all pregnancy losses.

The second stripe is very weak, what is the reason?

If a second line is detected on the test, but the color is not clear, then regardless of saturation, this indicates the presence of pregnancy. Weakness of staining may be due to the following reasons:

• insufficient hCG levels;
• the test was not done on morning urine;
• the test has low sensitivity;
• the woman drank a lot of fluids the day before the test;
• taking certain medications that contain or cause the formation of hCG;

But there may be exceptions and the result may be false positive in the following cases:

• a miscarriage occurred;
• the presence of neoplasms in the body;
• expired;
• Incorrect use of the test (holding the strip longer than the specified time contributes to the evaporation of the liquid and coloring of the second strip);
• the mental state of the woman (rare cases when a woman who strongly desires to become pregnant provokes an increase in the level of the pregnancy hormone)

For accuracy, you can repeat the procedure after a couple of days or take a blood test.

Homemade pregnancy tests

There is a category of women who are still unable to access even such basic things as a pregnancy test. This is often due to lack of access to pharmacies or clinics in their area. Also, those who live below the poverty line are not able to afford such a purchase. Alternative Methods tests can be used by highly suspicious people or women or those who love experiments, the options are listed below:

• Sugar is one of the used ingredients in the kitchen of every home. This pregnancy test was most commonly used in the old days, several decades ago, when there were no other options. It is important to use only morning urine (the first portion after waking up). Pour 2-3 teaspoons of sugar into a bowl, add urine to it, or urinate directly into the bowl. After a few minutes, pay attention to the reaction of sugar with urine. If the sugar has dissolved, the result is negative. Well, if it fell into sediment or formed lumps, it’s positive. The hCG hormone prevents glucose from dissolving.
• Toothpaste is another ingredient that is found in every home. This test is very convenient to carry out, since toothpaste Take it with you even on a trip. Again, you will need a portion of morning urine, which is absolutely undiluted. So, take a small amount of regular toothpaste in a bowl and mix it with urine using a brush. If the color of the mixture turns out to be bluish, this means that the subject is most likely in an interesting position. However, you should not rely entirely on this test as it may be inaccurate in rare cases. It is important to note that there are no exact proportions that need to be mixed, therefore the result can be quite confusing.
• Vinegar. Mix a small amount of vinegar with morning urine and observe the coloring to see the result. A change in color indicates pregnancy.
• Potassium permanganate. To begin, dilute potassium permanganate in warm water, then pour the first portion of urine into the solution a little at a time. If the color turns yellow or fades, the result is negative. Increasing pink or purple hue with the formation of flakes is positive.
• Iodine. Add a couple of drops of iodine to the urine; if the iodine dissolves, fertilization does not occur; if the drops remain on top of the urine, congratulations!

In case of delay menstrual cycle, regardless of the test results, it is recommended to visit a gynecologist for consultation on the causes of such a malfunction in the body.
