HCG - norm

HCG, or human chorionic gonadotropin - a hormone released during pregnancy. HCG is produced in the body of a pregnant woman trophoblast. The structure of this hormone is similar to the structure of follicle-stimulating, luteinizing hormone. In this case, hCG differs from the above hormones by one subunit, which was designated as beta. It is on this difference in the chemical structure of the hormone that a standard pregnancy test and tests conducted by doctors are based. The difference is that the standard pregnancy test determines the level of hCG in the urine, and the tests prescribed by the doctors are in the blood.

The effect of hCG on the body of a woman

Human chorionic gonadotropin is a hormone that promotes the development of pregnancy. Due to its biological effect, the body maintains the function of the yellow body at the initial stages of pregnancy. The yellow body synthesizes progesterone - the hormone of pregnancy. On the background of the synthesis of hCG, the placenta is formed, which subsequently also produces hCG.

Analysis of hCG - norm

HCG is normal in non-pregnant women and hCG is normal in men is 6.15 IU / L.

Free beta hCG - norm

For non-pregnant women, the free beta subunit of hCG in normal venous blood is up to 0.013 mIU / ml. For pregnant women, hCG free in norm for weeks is in mIU / ml:

The norms of HCG in DPO

The level of human chorionic gonadotropin on days after ovulation (DPO) in mIU / ml:

HCG - norms in IU / L and MoM

The level of hCG is measured in two units, such as ME / L and mMe / ml. The norm of hCG in Me / l for weeks is:

MOM is the ratio of the hCG level obtained as a result of the study to the median of the value. 0.5-2 MoM is the physiological norm of the indicator for pregnancy.

The norms of RAPP A and hCG

Rarre alpha is a plasma-associated protein. The level of this protein is an important marker of the presence of chromosomal abnormalities in the fetus, diagnosis of the course of pregnancy. The study of this marker is relevant until the 14th week of pregnancy, in later terms, the analysis is not informative.

Rates of RARP alfa by week of pregnancy in Honey / ml:

Antibodies to hCG - norm

In the blood of a pregnant woman can form cells - antibodies that destroy the hormone hCG. This process is the main reason for miscarriage, since in the absence of hCG, the hormonal background of pregnancy is disrupted. Normally, the blood can be up to 25 U / ml antibodies to HCG.

And if hCG is higher than normal?

If the level of human chorionic gonadotropin is higher, in non-pregnant women and men this may be a consequence of the presence of hormone-producing tumors:

An increase in the level of hCG in pregnant women can be the result of a multiple pregnancy, while the level of hCG increases in direct proportion to the number of fruits.

What does it mean if the HCG is lower than normal?

Lowering the level of HCG lower than normal in pregnant women can be a sign:
