How does HCG determine whether a pregnancy is intrauterine or ectopic?

HCG generally refers to human chorionic gonadotropin. Generally, it is not possible to judge whether the pregnancy is intrauterine or ectopic based on the level of human chorionic gonadotropin.

Human chorionic gonadotropin is a hormone secreted by placental trophoblast cells. Generally speaking, trophoblast cells begin to secrete trace amounts on the sixth day after pregnancy. It can be detected from the mother's serum around 10 days into pregnancy, which is the most sensitive method for diagnosing early pregnancy. However, intrauterine or ectopic pregnancy cannot be determined based on chorionic gonadotropin levels. To determine intrauterine or ectopic pregnancy, you need to wait for the menstruation to be delayed for 15 to 20 days and go to the hospital for vaginal B-ultrasound or abdominal color ultrasound diagnosis. Through vaginal B-ultrasound or abdominal color ultrasound, you can not only understand intrauterine or ectopic pregnancy, but also understand the development of the embryo.

If the examination shows that the pregnancy is intrauterine and the fetus is developing normally, a normal pregnancy can be carried out. If it is an ectopic pregnancy, a normal pregnancy is usually not possible and the pregnancy needs to be terminated in time under the guidance of a doctor.
