The HCG value is mainly used as a check indicator to determine early pregnancy. high HCG value is related to various factors such as early pregnancy, incomplete miscarriage and diseases, and the cause should be judged according to the patient’s specific situation. 1. early pregnancy: women of reproductive age with normal sexual life who have elevated HCG value should consider whether it is caused by pregnancy. After the fertilized egg moves to the uterine cavity and lays in the uterus, the embryo is formed, and during the development and growth of the fetus, the placental syncytial trophoblast cells produce a large amount of HCG, usually the blood HCG of women with intrauterine pregnancy is >10mIU/ml, and there is the phenomenon of doubling every other day; 2. The patient needs to go to the hospital for relevant examination in time to make a clear diagnosis. If the miscarriage is incomplete, the patient needs to undergo surgery to clear the uterus in time; 3. Disease factors: such as staphyloma, choriocarcinoma, teratoma, etc., generally the HCG value is higher than the normal early pregnancy value, and it is necessary to cooperate with ultrasound examination and pathological diagnosis for differential diagnosis before treatment. Patients with elevated HCG values are advised to go to the hospital for relevant examinations in a timely manner. If the disease is diagnosed, treatment should be provided as soon as possible.
