Pregnancy is a very important thing for women who are preparing for pregnancy. Most women basically have pregnancy test sticks at home, but some women find that there are two lines after using the pregnancy test stick, but they go to the hospital for a check-up and find that they are not pregnant. The reason for this phenomenon may be that there is a problem with the pregnancy test stick itself, or it may be caused by improper operation, but it may also be a false pregnancy. Why are there two bars when you are not pregnant? When this happens, it is often attributed to quality problems with the pregnancy test stick itself or improper methods of the operator. Factors such as whether the pregnancy test stick is expired, damp, or of substandard quality, whether the operator inserts the correct end into the mid-stream urine, whether the test urine is non-morning urine for early pregnant women with low hormone secretion, and whether the test results are checked between 3 and 5 minutes, will affect the test results. When is it more accurate to use a pregnancy test stick? After pregnancy, human chorionic gonadotropin (HCG) is produced in the pregnant woman's body, which helps maintain the pregnancy. Pregnancy test sticks are determined by measuring HCG in urine. If human chorionic gonadotropin is detected in the urine, it is normally a sign of pregnancy. Generally speaking, after a woman is fertilized during her ovulation period, it takes at least 6 to 7 days for the fertilized egg to produce chorionic gonadotropin, but generally speaking the level is still relatively low and is easily undetectable. HCG actually starts to be secreted in large quantities after the fertilized egg implants, and the syncytial trophoblast begins to secrete large amounts of HCG. It takes at least 11 days for the fertilized egg to implant, so if you want to get a relatively accurate pregnancy test result, wait 11 days after having sex. What are the reasons for false positive pregnancy test? 1. Effect of ovulation drugs Why does a false positive occur in an early pregnancy test? What are the reasons for a false positive in an early pregnancy test? It is understood that one of the common reasons for a false positive in an early pregnancy test is that the woman has used HCG ovulation-inducing drugs during the luteal phase. HCG ovulation-inducing drugs will affect the accuracy of the test, so women with false positives in early pregnancy tests need to consider whether it is due to the influence of ovulation drugs. 2. Wrong pregnancy test method Another common reason for false positive pregnancy test sticks is due to incorrect pregnancy testing methods. It is understood that generally speaking, early pregnancy test strips must be used when women have amenorrhea for more than one week. The morning urine test is the most accurate, so a false positive pregnancy test strip is likely caused by an incorrect pregnancy testing method. 3. Hemolysis Another possible cause of a false positive pregnancy test result is hemolysis in the female body. There are many symptoms of hemolysis. If a woman suffers from hemolysis, it will inevitably affect the results of the pregnancy test. 4. Other reasons Since each woman's actual physical condition is different, we cannot make a general statement. A false positive pregnancy test also needs to be considered whether it is due to hydatidiform mole, HCG tumor cells, kidney cancer, and other diseases. |
