Normal hcg value at 53 days of pregnancy

The normal value of hcg at 53 days of pregnancy should be between 3697-149571 mIU/mL. To detect whether a woman is pregnant, you only need to see whether the hcg value is normal. The hcg value changes every week after a woman becomes pregnant. The hcg value in the later stages of pregnancy is definitely much higher than that in the early stages of pregnancy. Therefore, it is best to pay attention to the changes in this value during each prenatal check-up after a woman becomes pregnant. In addition, pay attention to eating nutritious foods and get more rest.

HCG is human chorionic gonadotropin, a glycoprotein secreted by the trophoblast cells of the placenta and composed of two subunits, α- and β-. Common detection methods include blood hCG detection and urine hCG detection. This test determines whether a woman is pregnant by checking the presence of β-subunits in the blood and urine.

Normally, hCG enters the maternal blood after fertilization and proliferates rapidly until the 8th week of pregnancy, then slowly decreases in concentration until the 18th to 20th week, and then remains stable. Generally, the β-HCG radioimmunoassay value of a normal person is less than 3.1 (mIU/ml). If it exceeds 5, the possibility of conception can be considered. If it exceeds 10, pregnancy can be basically confirmed. The urine -HCG of women with multiple pregnancies is often higher than that of women with single pregnancies. In addition, serum HCG should return to normal 9 days after delivery or 25 days after artificial abortion. If this is not the case, abnormality should be considered.

What is the normal hcg value at 53 days of pregnancy?

Depending on the unit of the hcg value, the value will also change (the gestational age is calculated from the last menstrual period).

If the reference value on the test report you received is in ng/ml, you should convert it by multiplying it by 3.18 to get the unit of nmol/L.

The following are the hcg reference values ​​in nmol/L:

7 weeks of pregnancy: 52.7-100.1 nmol/L

8 weeks of pregnancy: 64.6-113.8 nmol/L

9-12 weeks of pregnancy: 78-159.2 nmol/L

13-16 weeks of pregnancy: 98.3-185.7 nmol/L

17-20 weeks of pregnancy: 153.8-241.2 nmol/L

21-24 weeks of pregnancy: 234.6-457.4 nmol/L

25-34 weeks of pregnancy: 403.4-626.2 nmol/L

After 35 weeks of pregnancy: 483.6-776.8 nmol/L

Below are the hcg reference values ​​in mIU/ml:

Normal people: 0-3mIU/ml

3 weeks of pregnancy: 5.8-71.2mIU/ml

4 weeks of pregnancy: 9.5-750 mIU/ml

5 weeks of pregnancy: 217-7138 mIU/ml

6 weeks of pregnancy: 158-31795 mIU/ml

7 weeks: 3697-163563 mIU/mL

8 weeks: 32065-149571 mIU/mL

9 weeks of pregnancy: 63803-151410 mIU/ml

10 weeks of pregnancy: 46509-186977 mIU/ml

11-12 weeks of pregnancy: 27832-210612 mIU/ml

13-14 weeks of pregnancy: 13950-62530 mIU/ml

15 weeks of pregnancy: 12039-70971 mIU/ml

16 weeks of pregnancy: 9040-56451 mIU/ml

17 weeks of pregnancy: 8175-55868 mIU/ml

18 weeks of pregnancy: 8099-58176 mIU/ml

What is the normal value of hcg to indicate pregnancy:

Because the normal reference value of hcg for normal people is: the normal value of blood HCG is <10μg/L, and the normal value of β-HCG is <3.1μg/L. Therefore, when the normal value of blood HCG is greater than 10μg/L and the normal value of β-HCG is greater than 5μg/L, it can be preliminarily determined that the woman is pregnant.

Characteristics of pregnancy based on hcg values:

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. Normally developed villi secrete a large amount of HCG, and the daily titer continues to rise rapidly, increasing by more than 66% every 48 hours. That is, if the amount of β-HCG increases by more than 66% every two days, it can be diagnosed as intrauterine pregnancy. If the increase is less than 66%, there is a high possibility of ectopic pregnancy or intrauterine pregnancy hypoplasia.

After a woman becomes pregnant, an increase in β-HCG can be detected in her blood from the 9th to 11th day, and the amount of β-HCG can double every two days thereafter (even if there is threatened miscarriage, the rate of increase in HCG will not change). For example, if today's value is 234, if the test result the day after tomorrow is around 450, it can be considered as normal intrauterine pregnancy.

If the rate of increase is slow for two consecutive times, it indicates an ectopic pregnancy or abnormal development of the embryo. For example, if the HCG value is 10 today, 15 the day after tomorrow, and 17 two days later, such an HCG value is definitely abnormal, and the success rate of preserving the pregnancy is extremely low. If the HCG value continues to drop significantly, it is best to perform a uterine curettage even if the fetal heart rate is detected by B-ultrasound, as this indicates that the fetus is actually brain dead.

However, if the HCG increases very quickly, it indicates the possibility of hydatidiform mole, which must be closely monitored. Of course, it may also be twins.
