A common and simple method to check for pregnancy is to have a urine test, which can only be detected around 40 days of pregnancy. To detect pregnancy earlier, blood HCG testing can be performed. This method requires going to the hospital for examination, and the accuracy of the examination is quite high. So, how long does HCG testing take for pregnancy?
The fertilized egg does not produce HCG during fertilization. Only when the fertilized egg implants into the endometrium, nourishing cells begin to gradually secrete HCG. At the beginning of pregnancy, HCG grows faster, doubling every 48 hours.
HCG secretion begins at the time of implantation of the fertilized egg, around seven days after intercourse. Therefore, blood HCG testing can be performed around seven to eight days after intercourse, when the concentration of HCG is also high. If you pass the urine test, it will be relatively late, about ten to fourteen days after sexual intercourse, and can be detected.
Generally speaking, a blood test HCG value of 3.1 is required for normal non pregnant women, while a blood test HCG value of 5 during normal pregnancy can be considered as pregnant, and a HCG value of 10 can basically confirm pregnancy. The HCG values of pregnant mothers vary in different months, and we need to take a dialectical approach.
