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.
