Once a woman is pregnant, she can use an early pregnancy test strip to quickly test the level of human chorionic gonadotropin, a specific hormone in her urine, to determine whether she is pregnant. If the test result is negative, it means you are not pregnant; if it is positive, it means you are pregnant. So is it accurate to get a negative result 16 days after having sex? Generally, the test will be more accurate if the menstrual period is delayed by 7-10 days. Temporary observation for a few days. This type of test has the advantages of being rapid, convenient, flexible, and highly specific, but don't take chances, because when using an early pregnancy test strip, if you don't pay attention to some unexpected conditions, a false negative or positive result may occur. How to improve the success rate of early pregnancy test strips? Pay attention to the production time on the gift box and do not use expired early pregnancy test strips, because organic chemicals are ineffective if used for a long time or stored improperly. Please read the instructions carefully before testing the blood and follow the instructions carefully. Supplement: If you do an early pregnancy test at night, the success rate will be affected to some extent, while using morning urine will produce more accurate results. Many early pregnancy test strips indicate that women can do an early pregnancy test 1 to 2 days after missing their normal menstrual period. If the test result is negative and your period still occurs after 1 week, you should do another test. At the beginning of full-term pregnancy, or with ectopic pregnancy, the urine to be tested needs to be left for more than 3 minutes (usually only 1 minute is needed), and carefully identify whether there is a weak positive, that is, the color of the test area is lighter than the color of the comparison area or only appears vaguely. Pay attention to test positive results caused by non-pregnancy factors, such as blood in the urine, endometrial hyperplasia, uterine and ovarian tumors, recent pregnancy, missed abortion or incomplete abortion. It should be noted that using early pregnancy test strips for pregnancy testing is only a basic test and should not be used as the final test result. Going to the hospital for a comprehensive and special examination is the most reliable and reassuring thing. |
