Urine pregnancy latex agglutination inhibition test

In addition to the functions of nutrition, respiration and excretion of the fetus, the placenta during pregnancy also has the function of synthesizing and secreting various endocrine hormones. Among them, chorionic gonadotropin (HCG) can be used as an important indicator for the diagnosis of early pregnancy and trophoblastic tumors. HCG mainly exists in the blood, urine, colostrum and fetal body of pregnant women. The placenta begins to secrete HCG from 0 to 14 days after conception, and reaches a peak at 10 weeks, and then gradually decreases. HCG has a strong antigenicity and can be used to immunize rabbits to produce high-valent antibodies for the detection of pregnancy immunology. Commonly used methods are latex agglutination inhibition test and early pregnancy test and pregnancy dilution test.
