The accuracy of hcg blood test 8 days after sex

We all know that although hcg is currently the fastest and most accurate way to check female pregnancy, it is still necessary to wait 7 days after the embryo implants and the hcg value detected in the blood can determine whether a woman is pregnant. If you are too anxious and do a blood test before 7 days of embryo implantation, the hcg value tested at this time will definitely be 0 but less than 10.

If the hcg value is higher than 0 and lower than 10, no conclusion can be drawn immediately. It must be based on re-examination before a conclusion can be drawn. So how accurate is the hcg test 8 days after intercourse? If you are pregnant on the day of intercourse, then the embryo implantation process takes about 7 days. In other words, one day after the embryo implants, can the hcg value of the hcg blood test indicate whether you are pregnant or not? How accurate is it?

In fact, if it is less than 7 days after the embryo implants, the hcg value tested will definitely be greater than 0 and less than 10. Of course, if a blood test is done to check hCG one day after the embryo is implanted, the hCG value will definitely be small. However, if the hCG blood test is done less than 7 days after the embryo implants, the hCG values ​​detected are all above 0 and below 10. This standard value cannot draw a conclusion. It only indicates the possibility of pregnancy and needs to be re-examined. The results of the review can lead to conclusions. In other words, the accuracy of hcg blood test 8 days after intercourse is 50%.

Of course, having sex does not mean that you will definitely get pregnant. If you don't get pregnant after having sex, then the hcg value is definitely lower than 10. However, there are many factors that can cause the hcg value to exceed 0, so the hcg value may be greater than 0 but lower than 10. Therefore, the accuracy of hcg blood test 8 days after sexual intercourse is also 50%. Since a review is required, the results of the review are critical.

Therefore, we must understand that it does not mean that you will get pregnant if you have sex. Even if you can get pregnant, it is too hasty to do a blood test 8 days after having sex. The results of the blood test at this time may not show anything and need to be rechecked. Of course, no matter how much the hcg value tested is, if the hcg value is 0 but lower than 10, it needs to be rechecked, and the accuracy is 50%. In other words, the accuracy of hcg blood test 8 days after intercourse is 50%.
