hcg reference value in early pregnancy

There are many ways to test for early pregnancy in women. For women, they can check whether they are pregnant through urine tests or blood tests. After most people become pregnant, the hormones in their bodies continue to rise. Therefore, the hcg value will be high in the early stages of pregnancy. However, the hcg reference value is different at different stages of pregnancy, but it is always in an upward stage. So what is the hcg value in one week of pregnancy?

What is the hcg level in one week of pregnancy?

Normal value of urine hcg in one week of pregnancy

Urine-hcg (hcg semi-quantitative method): non-pregnant women <25μg/L, 40 days of pregnancy >5000μg/L, 60-70 days of pregnancy >(8-32)×104μg/L (urine hcg level is highest in the early morning, close to serum level).

HCG test paper is a urine test for hCG. Generally, it can only be tested when the hCG value in the urine reaches 10 or above. There are different models of hcg test strips. When testing, operate according to the model. When the result shows two red strips. One line is located in the control area C and the other is located in the test area T, indicating pregnancy. Although urine HCG test is simple and convenient, the error is relatively large, so pregnant women are advised to do blood HCG test.

In addition to determining whether a pregnant woman is pregnant, hcg has other functions.

1. Determine the physical condition of the pregnant woman.

The normal value of blood hcg is <10μg/L, and the normal value of β-hcg is <3.1μg/L. β-hcg is a part of hcg. Generally, the β-hcg radioimmunoassay value of a normal person 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. 35-50 days after pregnancy, hcg can rise to greater than 2500IU/L. The urine -hcg level in women with multiple pregnancies is often higher than that in women with single pregnancies. Serum hCG should return to normal 9 days after delivery or 25 days after artificial abortion. If this situation is not met, the possibility of abnormality should be considered.

2. Determine whether it is an ectopic pregnancy.

HCG is a specific hormone secreted during pregnancy, so early diagnosis of ectopic pregnancy can be determined by testing blood hCG. It is difficult to have an exact number for the normal hcg value for ectopic pregnancy, and we can only distinguish it based on the comparison of different data. HCG examination can be used to differentiate abdominal pain caused by ectopic pregnancy from other acute abdominal diseases. For example, in the case of ectopic pregnancy, the positive rate of hCG detection is only 60%, and hCG may still be positive 3 days after uterine bleeding.

Health Tips

The absolute value of blood hCG varies greatly at different stages of pregnancy and between pregnant women, but the hCG values ​​between different pregnant women in the same pregnancy period may be different. Therefore, the hCG value can only be used to distinguish the pregnancy time based on its own changes.
