How to read the results of blood test for early pregnancy

We all know through various media channels that we can check whether a woman is pregnant by taking a blood test, but many women still don't know whether they are pregnant after getting the test results. In fact, the test results of a blood test for pregnancy are very easy to read. Everyone can read them through learning. So how do you judge the results of a blood test for pregnancy?

How to judge the results of blood test for pregnancy

The key to blood test for pregnancy is to look at the blood hcg value. The hCG test is a way to determine whether a woman is pregnant by accurately measuring the hCG level in her blood. The test mainly uses the hCG value to determine whether you are pregnant and whether it is a normal pregnancy. It can be diagnosed whether the pregnancy is in the early stages 8-10 days after having sex. The test results can usually be obtained on the same day. If the blood is drawn in the morning, the result can be known at noon.

The standard value of blood hCG is lower than 10μg/L, and the standard value of β-hCG is lower than 3.1μg/L. β-hCG is a part of hCG. Generally, the β-hCG radioimmunoassay value of a normal woman is lower than 3.1. If it exceeds 5, the possibility of pregnancy can be considered, and if it exceeds 10, pregnancy can be basically confirmed.

The absolute values ​​of hCG in blood cells vary at different stages of pregnancy and among pregnant women. There is no comparability between them and they can only be compared with each other. During the first three months of pregnancy, hCG levels approximately double every 2.2±0.5 days.

Human chorionic gonadotropin enters the maternal blood after fertilization and multiplies rapidly until the 8th week of pregnancy, then slowly decreases in concentration until the 18th to 20th week, and then remains there for a long time. Generally, a level of at least 2.5 MoM of human chorionic gonadotropin is associated with Down syndrome.

How much hcg is considered pregnancy in a blood test

1. Confirmation of early pregnancy: hCG can rise to more than 2500IU/L 35 to 50 days after pregnancy. It reaches 80,000 IU/L in 60 to 70 days. The urine hCG of multiple pregnancies is often higher than that of single pregnancies.

2. Differentiation between abnormal pregnancy and placental function:

(1) Ectopic pregnancy: In the case of ectopic pregnancy, this test can only have a 60% positive rate. Three days after abnormal uterine bleeding, hCG can still be positive, so hCG testing can be used to distinguish it from other acute abdominal diseases. hCG is usually between 312 and 625 IU/L.
