HCG reference range table

The HCG content in a woman's body will change after she becomes pregnant. In the early stages of pregnancy, the HCG content in the body will change with the development of the fetus. What is the HCG reference range table for early pregnancy? HCG is a sex hormone. HCG levels in pregnant women will double. If it is an ectopic pregnancy, HCG will also change. Therefore, women in early pregnancy need blood tests every time they have a check-up. Let's learn about the detailed introduction of HCG.

1. What is the hcg reference value

HCG is human chorionic gonadotropin, a glycoprotein secreted by trophoblast cells of the placenta. The amount of HCG secreted by normally developed villi is very large, and the titer continues to rise rapidly every day, increasing by more than 66% every 48 hours.

Ectopic pregnancy is a common disease in obstetrics and gynecology. The domestic incidence rate is reported to be 1:79. The statistical incidence rate in 11 months is 3.55%, 1.33% in the first 5 months, and 5.36% in the last 6 months, which is an exponential increase. The Department of Obstetrics and Gynecology has launched a blood HCG quantitative detection project, which is of great significance in the diagnosis, differential diagnosis, selection of treatment and treatment plans, and observation of efficacy of gynecological diseases that may exist in expectant mothers, especially mothers with acute abdomen.

2. What is the reference value of blood hcg?

Expectant mothers need to treat the issue of blood hcg reference values ​​correctly. Generally, the normal blood HCG radioimmunoassay value is less than 3.1. If it exceeds 5, the possibility of conception can be considered. If it exceeds 10, pregnancy can be basically confirmed. HCG can rise to greater than 2500IU/L 35-50 days after pregnancy. The urine HCG of women with multiple pregnancies is often higher than that of women with single pregnancies.

The absolute values ​​of serum HCG vary greatly at different stages of pregnancy and between pregnant women, that is, they are different from person to person and are not comparable, and can only be compared within themselves. Generally, non-pregnant women’s blood HCG is <100IU/L. During the first 3 months of pregnancy, HCG levels approximately double every 2.2±0.5 days.

3. What is the reference value of hcg during pregnancy?

One way to determine whether a woman is pregnant is a blood HCG test, which is to measure the HCG value in the blood. Compared with traditional urine HCG, blood HCG is more accurate, has smaller errors, and can be tested earlier. What is the reference value of HCG during pregnancy? The normal value of HCG during pregnancy is <3.1μg/L.

Usually on the 11th day after the menstrual period, a blood test for HCG will show a positive result if pregnancy is confirmed. If pregnant, 85% of pregnant women will have their blood HCG level double every two or three days. If HCG does not increase at this rate, it means you are not pregnant.

4. What is the reference value of hcg during pregnancy?

HCG increases very quickly in the serum during early pregnancy, doubling in about 1.7-2 days. The serum concentration reaches its peak at 8-10 weeks of pregnancy, and continues until 12 weeks, when it rapidly decreases and then maintains a certain level.

The HCG reference values ​​for the entire pregnancy are as follows:

3-4 weeks of pregnancy: 9-130 (mIU/ml)

4-5 weeks of pregnancy: 75-2600

5-6 weeks of pregnancy: 850-208003

6-7 weeks of pregnancy: 4000-100200

7-12 weeks of pregnancy: 11500-289000

12-16 weeks of pregnancy: 18300-137000

16-29 weeks of pregnancy: 1400-53000

29-41 weeks of pregnancy: 940-60,000
