Can PH test paper detect pregnancy? The PH test paper cannot detect pregnancy. This test paper mainly detects the pH level in urine, while a pregnancy test strip is required to detect pregnancy. The pregnancy test strip mainly detects human chorionic gonadotropin in urine. If the test shows two bars, it indicates pregnancy. If it shows one bar, it does not necessarily mean that you are not pregnant, for example, if the time since sexual intercourse is relatively short. Even if you are pregnant, the pregnancy test strip may not be sensitive enough to detect it, so it is more accurate to test about two weeks after sexual intercourse. Alternatively, you can go to the hospital for a blood test for HCG about ten days after sexual intercourse to check for pregnancy.
Generally speaking, a pregnancy test can detect whether a woman is pregnant three days after her menstrual cycle is delayed, and the result will be more accurate if the test is performed after a week's delay, as the HCG level will increase significantly at this time. Take the test strip out of the package for testing, and try to complete the test within one hour after tearing it open. If the usage of the pregnancy test strip is incorrect, the accuracy of the test result will be affected. To improve the accuracy of the pregnancy test strip, you should follow the correct usage instructions:
- Before testing, you must read the instructions completely and restore the reagent and urine sample to room temperature (20℃-30℃) before use.
- Remove the reagent strip from the original aluminum foil packaging and insert the reagent strip into the urine sample according to the arrow direction. Note: The urine level should not exceed the marked line on the reagent strip.
- Remove the reagent strip after at least 5 seconds and place it flat on a clean and flat surface to observe the result.
- Wait for the appearance of a purple-red band. The test result should be read within 3 minutes, and it will be invalid after 10 minutes.
