Can I detect pregnancy if I am in the same room as No. 1 or No. 11? What is the accuracy and time of the pregnancy test paper?

　　Pregnancy testing is a common yet questionable topic. Different detection times and methods will affect the accuracy of detection results. Next, we will discuss in detail whether roommate No. 1 and No. 11 can detect pregnancy and the accuracy and timing of the pregnancy test paper.

Can a pregnancy test be detected if room number 11 is in the same room as number 1?

　　Analysis of the process of conception: Generally speaking, female After having sex on the day of ovulation, sperm Combined with the egg to form a fertilized egg, this process usually takes 1-2 days. After the fertilized egg is formed, it will Uterus Move and implant. The implantation time is about 6-7 days after fertilization. After implantation, the placenta begins to secrete human chorionic gonadotropin (hCG), which is an important indicator of pregnancy. If intercourse on the 1st happens to be the day of ovulation, by the 11th, theoretically, the fertilized egg may have implanted in the uterus and begin to secrete hCG.

　　Possibility of test results: However, using an ordinary pregnancy test strip on the 11th may not accurately detect pregnancy. Because the level of hCG in the urine may still be relatively low at this time, the pregnancy test may not be able to detect it. However, if you use a highly sensitive pregnancy test strip, it is possible to detect a weak positive result, but there is also the possibility of false positive or false negative. In addition, individual differences will also affect the secretion speed of hCG. Some women may implant late and hCG secretion will be relatively late, so it is normal not to detect pregnancy on the 11th.

Pregnancy test accuracy and timing

　　Test accuracy at different times: In early pregnancy, the level of hCG in the urine is low, and the accuracy of pregnancy test strips will be affected. It is generally recommended to conduct the test 7-10 days after menstruation is delayed. At this time, the level of hCG in the urine is relatively high and the test results will be more accurate. If you test too early, such as a week or so after intercourse, you may not be able to detect pregnancy even if you are pregnant. The accuracy of detection will be greatly improved after menstruation is delayed for a long time.

　　Factors that affect accuracy: In addition to testing time, there are other factors that affect the accuracy of pregnancy tests. For example, if the test paper is expired or improperly stored, the test results may be inaccurate. In addition, the detection method is also critical. When using it, you must strictly follow the instructions to avoid operational errors that affect the results. At the same time, some disease Or medications may affect hCG levels, thereby interfering with test results.

　　Methods to improve accuracy: In order to improve the accuracy of pregnancy test strips, it is recommended to use morning urine for testing, because the concentration of hCG in morning urine is relatively high. Do not drink large amounts of water before the test to avoid diluting the hCG concentration in the urine. If the test result is positive, it is recommended to arrive in time Hospital Further examinations, such as blood hCG testing and B-ultrasound examination, are performed to confirm pregnancy and whether it is an intrauterine pregnancy.
