HCG, called chorionic gonadotropin, is a hormone secreted by the trophoblast cells of the embryo after pregnancy. If the level of HCG is greater than 10,000 miu/mL, it means that the level of the hormone is relatively high in the body. In this case, an ultrasound can be done and the development of the embryo can be seen underneath the ultrasound. If the HCG is lower than 10,000miu/mL, you can’t see the embryo development by ultrasound. So HCG is more than 10000miu/mL, this situation is better, which means the concentration of HCG is higher in the body. It is recommended to go to the hospital for ultrasound examination in time to see if the embryo is developing normally, whether there is germinal bud pulsation, whether there is yolk sac and fetal heart, which are all very important.
