Explanation and interpretation of blood tests on the beta-hCG
HCG content can be measured more precisely usingimmunological tests. A molecule of human chorionic gonadotropin has a complex structure and consists of two subunits (alpha and beta). b-hCG has a unique structure. Using antibodies specific thereto, carried quantification levels of beta-hCG in the patient's blood.
In clinical practice, this analysis is conducted atpregnancy (for screening and diagnosis of disease chromosomal trophoblastic disease). In oncology, the levels of b-hCG is used for the diagnosis of testicular cancer in men and women horionkartsinoma.
Units in the analysis - ng / mL.
The rate of b-hCG in healthy men and women - to 2 ng / ml.
The rate of b-hCG in pregnancy:
- Week 8 - 23-162 ng / ml;
- 11th week - 17-130 ng / ml;
- 18-week - 4-33 ng / mL.
Increase the value in men - oncomarker hormonally active tumors of the reproductive glands.
Increased values in women is pregnancy - oncomarker horionkartsinoma (an aggressive cancer of the chorionic villi).
Elevated levels of b-hCG pregnancy - a sign of the high risk of Down syndrome in the fetus. Significant growth indicators also serves as a diagnostic criterion for the molar pregnancy.
Keep in mind that the test results are not diagnosed and requires consultation gynecologist, oncologist and genetics.
