If the result is 110.23IU/L after 16 days of blastocyst transfer, it is considered that the embryo has been successfully implanted. Because the normal range of HCG in the infertile state is usually <5IU/L. There is hope in this case. Human chorionic gonadotropin (HCG) is a substance produced by the placenta when a woman is pregnant, and can therefore be used to determine whether she is pregnant. The current test results indicate that the embryo has successfully implanted and is currently pregnant. It is important to check the HCG regularly to see how it is doubling to determine how the embryo is developing. If the HCG value is unsatisfactory or decreases instead of increasing, the possibility of fetal arrest cannot be ruled out. After 4 weeks of embryo transfer, you need to go to the hospital for an ultrasound examination to clarify the specific location of the gestational sac and whether there is fetal heart buds. During pregnancy, you should take pregnancy test on time.
