What is the normal hcg value at 50 days of pregnancy?

Many female friends who have just become pregnant will find an item called hcg on the examination report when they go to the hospital for a check-up. The doctor will also focus on the value of this item to judge the condition of the pregnant woman. So what does hCG mean? What do its various values ​​represent? What is the normal hCG value found when checking at 50 days of pregnancy? Because many pregnant mothers do not understand these special values ​​in the early stages of pregnancy, about one and a half months, when they just find out, so with these questions, let's find the answers together today.

According to the hCG number used for reference by the American Pregnancy Association,

? 3 weeks postmenopause: 5 weeks - 50 mIU/ml ? 4 weeks postmenopause: 5 - 426 mIU/ml ? 5 weeks postmenopause: 18 - 7,340 mIU/ml

? 6 weeks postmenopause: 1,080 - 56,500 mIU/ml ? 7 - 8 weeks postmenopause: 7, 650 - 229,000 mIU/ml ? 9 - 12 weeks postmenopause: 25,700 - 288,000 mIU/ml

? 13 - 16 weeks postmenopause: 13,300 - 254,000 mIU/ml ? 17 - 24 weeks postmenopause: 4,060 - 165,400 mIU/ml ? 25 - 40 weeks postmenopause: 3,640 - 117,000 mIU/ml

? Postmenopausal women: <9.5 mIU/ml hCG Less than 5mIU/ml is a negative reaction, not pregnancy, any amount over 25mIU/ml is a positive reaction, pregnancy

The hcg value in a blood test at 50 days of pregnancy should be around 10,000 miu/ml. If it is not this number, there is no need to worry, because it will be lower if the pregnancy is late. As long as there is no abnormality, it is normal.

In fact, if pregnant, for 85% of pregnant women, the amount of hCG in their blood doubles every two or three days. If hCG does not increase at this rate, it means pregnancy has failed. The hCG number cannot be used to calculate gestational age. Because these numbers vary widely, women who are not pregnant generally have a mid-cycle level of 8 to 10, or even as high as 20 ng/ml. If pregnant, progesterone should be >10 to 12 ng/ml (preferably more than 16)

Now let us popularize the relevant knowledge of hcg.

1. What does hcg mean?

Human chorionic gonadotropin (hCG) is a glycoprotein secreted by trophoblast cells of the placenta, which is composed of α and β dimers of glycoprotein. The complete hCG is produced entirely by the syncytiotrophoblast of the placental chorion. Its main function is to stimulate the corpus luteum, which is beneficial to the continuous secretion of estrogen and progesterone, so as to promote the formation of uterine decidua and make the placenta grow and mature.

After the fertilized egg of a mature woman moves to the uterine cavity and implants, an embryo is formed. During the process of development and growth into a fetus, the placental syncytiotrophoblast cells produce a large amount of human chorionic gonadotropin (hCG), which can be excreted into the urine through the blood circulation of pregnant women. During the 1st to 2.5th week of pregnancy, the hCG level in serum and urine will increase rapidly, reaching a peak in the 8th week of pregnancy, and then drop to a moderate level in the 4th month of pregnancy, and remain until the end of pregnancy.

2. What is the normal range of hcg?

The normal value of blood hcg is <10μg/L, and the normal value of β-HCG is <3.1Iμg/L, which are within the normal range. Generally, the β-hcg radioimmunoassay value of a normal person is less than 3.1Iμg/L. If it exceeds 5μg/L, the possibility of conception can be considered. If it exceeds 10μg/L, pregnancy can be basically confirmed. 35-50 days after pregnancy, hcg can rise to greater than 2500μg/L.

3. Clinical significance of hcg examination:

The examination of hcg is of great significance for the diagnosis of early pregnancy, and has certain value in the diagnosis, differentiation and course observation of pregnancy-related diseases, trophoblastic tumors and other diseases.

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

2. Determination of abnormal pregnancy and placental function:

① Ectopic pregnancy: In the case of ectopic pregnancy, this test has only a 60% positive rate. HCG may still be positive 3 days after uterine bleeding, so HCG examination can be used to differentiate it from other acute abdomen. HCG is usually 312-625 IU/L.

② Diagnosis and treatment of miscarriage: In case of incomplete miscarriage, if there is still placental tissue remaining in the uterus, the hCG test may still be positive; in case of complete miscarriage or stillbirth, the hCG test will turn from positive to negative, so it can be used as a reference for fetal preservation or aspiration treatment.

③Threatened abortion: If the hCG level in urine remains high, inevitable abortion will not occur. If hcg is below 2500IU/L and gradually decreases, there is a possibility of miscarriage or stillbirth. When it drops to 600IU/L, miscarriage is inevitable. During the treatment to preserve pregnancy, if hcg continues to decrease, it means that the pregnancy preservation is ineffective. If hcg continues to rise, it means that the pregnancy preservation is successful.

④ 4 days after delivery or 13 days after artificial abortion, serum hcg should be lower than 1000IU/L, and 9 days after delivery or 25 days after artificial abortion, serum hcg should return to normal. If this situation is not met, the possibility of abnormality should be considered.

Finally, I think these prenatal test values ​​are very important for a female friend who has just become pregnant. In fact, not only pregnant friends, but also their husbands and relatives and parents should know more or less about this knowledge about pregnancy. This is the only way to better ensure the health of pregnant mothers and fetuses, because these values ​​can well reflect the changes in the body, so as to understand one's own health status. I hope all pregnant mothers and fetuses can be healthy and safe.
