Home tests for determining pregnancy quickly gained popularity in the market, as they have a lot of advantages. Now, women do not need to be queued to the gynecologist for every slightest suspicion of pregnancy, undergo examination, while spending material resources and time. Modern girls can simply go to the nearest pharmacy, purchase a home pregnancy test and within a few minutes find out the result, reliable in 98% of cases. The jet pregnancy test has won the favor of consumers, as it has a number of advantages compared to other types of express diagnostic methods. How and which test to choose, we will describe in our article.
How a jet test determines pregnancy
After the embryo is attached to the wall of the uterus, and this happens 5 to 7 days after conception, the woman’s body begins to produce chorionic gonadotropin for the proper development of the future baby. Starting from the second week of pregnancy, the hormone levels double every 2 days, reaching a maximum level of 12 weeks. Then indicators gradually decrease. Accordingly, identifying this hormone in the body of a woman, we can talk about the onset of conception. All rapid tests, including the jet pregnancy test, are based on the occurrence of a chemical reaction between the reagent applied to the test and the reagent - the hCG hormone. If there is a hormone in the body, a chemical reaction will occur and the reagent will change color, which will be reflected on the test in the form of a strip, plus or electronic inscription.
Benefits of Jet Testing
In fact, the inkjet test does not differ from the strips for determining pregnancy. But there are a number of undoubted advantages:
- Higher sensitivity pregnancy jet test 20 - 15 mIU / ml. This means that he can determine a lower quantitative content of hCG in the urine. And, accordingly, a reliable result will be obtained at an earlier date, when the hormone levels are still low. The test is carried out from the first day of the delay of menstruation, and some show the result several days before the alleged female discharge.
- Manufacturers claim that the reliability of the results reaches 98%.
- In addition, for the diagnosis of pregnancy using a jet test, there is no need to collect urine in a glass, which causes a lot of inconvenience to a woman and is an unhygienic process. You can even analyze at work - you only need a test and a few free minutes.
Pregnancy Inkjet Test Instructions
Pregnancy jet tests work on the same principle. But before use, you must carefully read the instructions. Since in case of non-compliance with any details specified by the manufacturers, the diagnostic results may be unreliable. Before use, make sure that you have purchased an unspoiled, expired jet pregnancy test. Instructions for use for most systems of this type are as follows:
- Remove the cap from the test, most often highlighted in a different color from the case.
- Substitute under the stream of urine. Hold for 5 seconds.
- Close the cap.
- Put a test on a horizontal surface.
- After 2 minutes, the result appears.
- In most inkjet tests, the result is valid 10 minutes after contact with the reagent.
Rules for using inkjet tests
For the reliability of the result when conducting an analysis using inkjet rapid tests to determine pregnancy, you need to familiarize yourself and follow some recommendations:
- pregnancy jet test is one-time, it cannot be reused;
- analysis should be carried out at room temperature;
- It is recommended to do an express diagnosis in the morning, since it is in the first urine that the highest concentration of human chorionic gonadotropin accumulates during the day;
- proper storage of the dough plays an important role in the reliability of the result: store unopened dough in packaging at room temperature, avoiding places in direct sunlight;
- do not take medicines on the eve of the analysis;
- drinking a large volume of fluid before diagnosis can show a false negative result by diluting the concentration of the hormone in the urine;
- if there is a negative result, but no menstruation or other indirect signs of pregnancy, repeat the test after 2 days or later. Previously, it makes no sense to test, since hCG increases after 2 days.
To obtain reliable results, use the pregnancy jet test strictly according to the instructions. The photo below shows a positive analysis result.
Interpretation of Results
Everything is very simple! 2 minutes after the test, a test strip should appear. It only means that the test is suitable and not spoiled. Now we observe the result in the control window. If there is even a slightly noticeable strip or “plus sign”, the inscription pregnant or a smiling emoticon - congratulations, you are pregnant! The absence of a strip, minus, the inscription no pregnant or a sad face in the control window means a negative result.
Causes of False Results
Sometimes false positive or false negative results. In the first case, the analysis procedure may have been violated according to the instructions, the test was damaged or its expiration date was expired. Also, the bar in the control window will not appear if the concentration of the hCG hormone is too low - repeat the test after a few days.
A false-positive test most often occurs in certain diseases during which hCG is produced:
- the residual phenomenon of the hormone is observed after recent abortions, miscarriages, ectopic pregnancy;
- various tumors, including cysts and malignant tumors can increase the concentration of hCG;
- various diseases of the hormonal system.
