How long is the pregnancy?

Pregnant women will undergo various prenatal examinations during pregnancy. The specific purpose of each examination is different, but they are all to check whether the condition of the pregnant woman and the fetus is normal. hCG test can accurately judge whether the pregnancy status is normal. If it is in the early stage of pregnancy, is hCG140 normal? How long is the pregnancy period when hCG140 is normal?

How long is the pregnancy?

If you are pregnant, you can use the hcg value to determine the time of pregnancy, and the test results are usually more accurate. If a blood test shows that the hcg gonadotropin value is 140, it means that the pregnancy time is very short, at most less than a week. This hcg gonadotropin value cannot accurately determine the actual length of pregnancy and needs to be determined based on the size of the gestational sac in the early stage, which is more accurate. Generally, the gestational sac can be seen 40 days after menstruation.

Is hcg140 normal in early pregnancy?

Because each hospital calculates the unit differently, if the unit of the blood hcg test result you get is ng/ml, you should calculate it by X3.18 to get the unit of nmol/L. Everyone should pay attention to the unit. The following is the standard value of the unit in nmol/L:

Progesterone reference value: 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

hcg standard value: pregnancy: 3--4 weeks: 9--130 (mIU/ml) pregnancy 4--5 weeks: 75--2600 pregnancy 5--6 weeks: 850--208003 pregnancy 6--7 weeks: 4000--100200 pregnancy 7--12 weeks: 11500--289000 pregnancy 12--16 weeks: 18300--137000 pregnancy 16--29 weeks: 1400--53000 pregnancy 29--41 weeks: 940--60000<

HCG and progesterone levels are not the same. Progesterone levels continue to rise, while HCG increases very quickly in blood cells in the early stages of pregnancy, doubling in about 1.7-2 days. The blood cell concentration reaches its highest point at 8-10 weeks of pregnancy, and continues until 12 weeks later, when it rapidly decreases and then maintains a certain level.

What does hcg mean

HCG is a glycoprotein metabolized by the trophoblast cells of the embryo. Generally, after a woman becomes pregnant, the embryo transforms into trophoblast cells and produces a large amount of human chorionic gonadotropin. It is composed of α and β dimers of glycoprotein. The α subunit is basically similar to the follicle-stimulating hormone, luteinizing hormone and thyroid-stimulating hormone metabolized by the pituitary gland, so they can cross-react with each other, while the structures of the β subunits are different. What does βhcg mean? βhcg is a component of hcg.

After a woman becomes pregnant, an increase in βhcg in the blood can be detected from the 9th to 11th day after fertilization, and the amount of βhcg can double every two days thereafter. Appreciate rapidly during the first 8 weeks of pregnancy to maintain the pregnancy. After about 8 weeks of pregnancy, hcg levels gradually decrease until they are relatively stable at about 20 weeks.

Generally, the β-HCG radioimmunoassay value of an average person 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.

Because hcg is a specific estrogen that needs to be metabolized during pregnancy, βhcg can be used to help diagnose early unruptured ectopic pregnancies. The amount of hcg secreted by normally growing hair is very large, and the daily titer continues to increase rapidly, increasing by more than 66% every 48 hours. If the amount of βhcg increase every two days exceeds 66%, it can be diagnosed as intrauterine pregnancy; if the increase is less than 66%, the possibility of ectopic pregnancy or incomplete intrauterine pregnancy is very high.
