After pregnancy, a female patient should have a blood HCG value of 5 μg/L or more, and a value greater than this is considered a possibility of pregnancy. If the result of the blood HCG test is greater than 10 μg/L, the diagnosis of pregnancy is basically clear. In the early stages of pregnancy, the blood HCG level will show a doubling. After the diagnosis of pregnancy, a pelvic ultrasound is also required to clarify whether the pregnancy is intrauterine or ectopic, in order to avoid bleeding disorders. In some cases, the HCG level may be abnormally high, such as staph, malignant staph, choriocarcinoma, etc. Therefore, patients with significantly higher blood HCG should go to a public hospital for pelvic ultrasound examination to make a clear diagnosis and choose the appropriate treatment according to the cause.
