There are special tests to determine pregnancy at home. And if earlier they were limited to simple stripes, now there is a wide choice of them. The simplest are still strips, while the most accurate are electronic pregnancy tests. There are also inkjet and tablet tests. The first type is more convenient to use, the second requires filling a special reservoir with urine, after which the results are obtained.
Pregnancy test works according to the following principle. From the first days of the conception of a child in the urine of a woman, the amount of chorionic gonadotropin sharply increases. Devices are treated with a special substance that reacts sharply to the presence of hCG, resulting in a positive result.
The most effective, modern and convenient today are electronic pregnancy tests. They have a number of advantages over other methods of determining the conception of a child. The first is the accuracy of the results. When using this device, the reliability of the result is guaranteed in 99%.
When urine gets on the test cartridge, the device displaysinscription: "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. The result is saved for 24 hours.
Electronic pregnancy tests are reusable devices, and this is another advantage of the new invention. The kit comes with 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 of using these devices. Manufacturers have developed them in such a way that when the device is connected to a computer, the latter processes data from the cartridge and can additionally calculate the expected date of birth of the child (if the results are positive) or the optimal day for conceiving a child if the results are negative. This is done by analyzing the level of chorionic gonadotropin and luteinizing hormone.
It is worth noting that, no matter how reliable data is shown by electronic pregnancy tests, in the early stages it is recommended to re-analyze 5-6 days after the first determination.
Thus, the electronic test isthe 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 have not yet become widespread among the female population.
