Serum human chorionic gonadotropin (HCG) is a common indicator of early
pregnancy diagnosis and can also be used for early detection and differential
diagnosis of abnormal pregnancy diseases.

0 to 25 mu g/L (0 ~ 10 u/L)
1. Serum HCG was increased, and was most common in women of child-bearing
age. After conception, the HCG content in the blood of normal people increased
rapidly, reaching the peak at 60-80 days of pregnancy, with a peak value of
10,000-12,000 g/L. Then, it gradually decreased, and fell to the lowest at
160-180 days of pregnancy, but was still significantly higher than normal.
During twin pregnancy, serum HCG more than doubled compared with single
pregnancy. During ectopic pregnancy, serum HCG was lower than normal pregnancy
value at the same time.
2. If the serum HCG of women with early pregnancy is significantly lower or
continuous monitoring shows a downward trend, it indicates threatened
abortion.
3. If the serum HCG value is still significantly higher than normal or on
an upward trend after the abortion operation, it indicates that the operation is
incomplete.
4. For patients who have been excluded from pregnancy, the measurement of
serum HCG is conducive to early detection of abnormal pregnancy diseases, such
as hydatidiform mole and chorionic epithelial cell carcinoma.
Fasting venous blood is usually collected in the morning or morning.
