To determine pregnancy at home, there are special tests. And if before they were limited to simple stripes, now there is a wide selection of them. The simplest are still strips, the most accurate are electronic pregnancy tests. There are also inkjet and tablet tests. The first type is more convenient to use, in the second it is necessary to fill the urine with a special reservoir, after which the results are obtained.
A pregnancy test works according to the following principle. From the first
days of the conception of a child, the amount of chorionic gonadotropin sharply increases in a woman’s urine. The devices are processed with a special substance that reacts sharply to the presence of hCG, as a result of which it shows a positive result.
The most effective, modern and convenient today are electronic pregnancy tests. They have several advantages compared to other methods for determining the conception of a child. The first is the accuracy of the results. When using this device, the reliability of the result is 99%.
If urine enters the test cartridge, the device displays “pregnant” if the result is positive, or “not pregnant” if the result is negative.
Electronic pregnancy tests do not change data over time, as happens with many other types of devices. In this case, the result is stored for 24 hours.
Electronic pregnancy tests are reusable devices, and this is another advantage of the new invention. Included are 20 disposable cartridges that are inserted into a special drive. In the future, you can purchase new strips, thereby reusing the purchased device.
The results are processed digitally, after which the data is displayed on a computer monitor. Electronic pregnancy tests are connected to a PC via a USB connector. And this gives another advantage to using these devices. The manufacturers developed them in such a way that when the device is connected to a computer, the latter processes the data from the cartridge and can additionally calculate the estimated date of birth of the child (if the results are positive) or the optimal day of conception of the child with negative results. This is done by analyzing the level of chorionic gonadotropin and luteinizing hormone.
It is worth noting that, no matter what reliable data electronic tests for pregnancy show, in the early stages it is recommended to re-analyze 5-6 days after the first determination.
Thus, the electronic test is the most convenient device to use, the definition of pregnancy on it is the most accurate. Its only drawback is the high cost, several times higher than the cheapest and simplest disposable test strips. And precisely because of this, electronic pregnancy tests are still not widely used among the female population.
