Every time the cycle calendar indicates a delay, millions of women anxiously go to the pharmacy and buy a pregnancy test. But it may be premature to be happy or sad about the result of the study. Oddly enough, tests are often wrong.
The most inexpensive pregnancy tests are strips impregnated with a special substance that responds to a hormone that begins to be produced in the body of a pregnant woman. There are some inconveniences here. It is imperative to conduct the test in the morning. In addition, after holding the strip in the urine for 20 to 40 seconds, you have to wait another ten minutes. Unfortunately, these strips very often give the wrong result. For example, if you immerse them in the liquid under investigation to an insufficient depth or inaccurately calculate the time. It often happens that the strip does not acquire the desired color.
Tablet tests are a little less likely to make mistakes. The liquid reaching the second window of this medical "blotting paper" starts a chemical reaction, and "hold-overexpose" here will not work. The cost of such tests is three times more expensive - approximately
100 rubles. But tablet tests are being replaced by more advanced tools.
Their more modern counterparts, jet tests, are fast and convenient. Using them, you do not need to wait in the morning, you do not need additional containers for the reagent. As part of these tests - a container with blue particles that catch the "pregnancy hormone" from one drop of urine that has got into the tester. The reliability of the indicators is almost 100%. The cost of such a tool is from 240 rubles.
Whichever choice you make, carefully study the packaging of the test - even the most reliable pharmacies sometimes offer low-quality products. The box must have the date of manufacture, batch number and expiration date. Check if the package contains detailed instructions in Russian. It is good if the phone numbers of the manufacturer's advisory line are indicated - so that you can ask questions that have arisen when using the test.
In addition, the reason for the test error may not be its poor quality at all, but the fact that you ran it too early. The onset of pregnancy introduces hormonal changes into the woman's body, sufficient for detection, no earlier than two weeks after conception. Therefore, it is useless to go to the pharmacy for a test the very next day after unprotected contact.
A mistake can also occur if a woman has some kind of tumor - the test will show a non-existent pregnancy. The use of hormonal drugs and ovarian dysfunction provoke a violation of the production of sex hormones, which affects the erroneous indications of a pregnancy test.
