The most accurate early pregnancy test
Tests are now commercially available to determine early pregnancy. A reliable result can be obtained already a week after the conception occurred, since the devices are highly sensitive to the hCG hormone. Tests for the diagnosis of early pregnancy make it possible to determine it even when the level of chorionic gonadotropin in the urine is 10 mIU / ml. As a rule, such a concentration of hCG is observed already seven days after conception.
To understand on which day the test can be performed for the first time, you need to remember the date when unprotected intercourse occurred. To this day, add another seven days and conduct testing. Thus, you can not wait for the first day of delayed menstruation, but find out about your position in advance.
When the egg has been fertilized in the middle of the cycle, the test can be performed for the first time after 7 days, rather than waiting until two weeks have passed (if the cycle is 28 days). If conception happened 1-3 days before the onset of menstruation, then the first time the test can be performed no earlier than 4 days after the delay in menstruation. These calculations are based on the fact that early pregnancy test systems are able to detect pregnancy 7 days after conception. In this case, the phase of the menstrual cycle or the duration of the delay of the next menstruation does not matter.
All tests, which have high sensitivity, are modern instruments that are very easy to use. They are part of the inkjet test group to make them easier to use. Manufacturers guarantee a reliable result 99% of the time.
Early pregnancy tests are available under brands such as ClearBlue, Evitest, Frautest, Sezam, Duet, Femitest jet ultra, Clear view and Ultra. They give a guaranteed reliable result, therefore, depending on her preferences, a woman can choose the device she likes best. The difference between them lies in their design, for example, you can find tablet or electronic tests, as well as in the display of the result and minor nuances of use.
All of these tests respond to human urine chorionic gonadotropin ranging from 10 mIU / ml. If the device has a reduced sensitivity, the manufacturer must indicate this on the packaging with the product, for example, 20 mIU / ml or 25 mIU / ml. It should be understood that only tests that are highly sensitive to hCG, that is, tests marked 10 mIU / ml, can diagnose pregnancy until the first day of missed period has come.
Test types:
-
Tablet tests are represented by a flat cassette with two windows. A few drops of urine are pipetted into one of them, and the result appears in the other window. If the test produces 1 strip, then there is no pregnancy, and if 2 strips, then the pregnancy has occurred.
- Inkjet tests are represented by an elongated plastic cassette. There is a plastic tip on one side of the device that needs to be placed in the urine. The test result appears in a window located directly on the device itself. The test can be placed under the stream of urine or the sensing tip can be immersed in it. The result will be in the form of stripes.
- Electronic pregnancy tests - these devices are always equipped with a digital display. At one end of the test is a tip that is placed in the urine, and at the other end of the instrument is a USB port. A stream of urine is applied to the tip, after which the result is displayed on a digital display. For additional information (for example, the date of conception of the child), the test must be connected to a personal computer.
Which pregnancy tests are most accurate?
The most accurate are pregnancy tests, the sensitivity of which is 10 mIU / ml. As a rule, these are digital inkjet tests that can show the result 4 days before the start of the next menstruation. Manufacturers point out that you can get a guaranteed reliable result (99% accuracy) if you test it 2 days before the expected monthly. When the test is performed earlier, the percentage of accuracy of the result is reduced.
The undoubted advantage of all such devices is that they can be used to determine early pregnancy. However, you will have to pay more for them than for regular tests.
The most affordable and reliable device is the ClearBlue digital test.
The most modern and advanced test is the Pteq diagnostic system. It is a digital instrument equipped with a USB connector. The test result can be seen after connecting the device to the computer. At the same time, you will have to pay about $ 18 for such a novelty.
