HCG (human chorionic gonadotropin) testing is commonly used in medical laboratories to diagnose pregnancy and monitor its progression. An immunoassay analyzer is a standard instrument used in these labs to detect HCG levels in a pregnant woman’s blood or urine sample. Immunoassay analyzers use techniques such as ELISA, CLIA, and FPIA to measure HCG levels during pregnancy.

ELISA, a commonly used technique during pregnancy diagnosis, involves mixing a pregnant woman’s sample with an HCG-specific antibody linked to an enzyme. The formation of an antigen-antibody complex causes a color change that indicates the presence of HCG in the sample, confirming the pregnancy. CLIA is another technique used during pregnancy diagnosis that involves mixing the sample with HCG-specific antibodies linked to a chemical that emits light when it comes into contact with the antigen-antibody complex. The amount of light emitted is proportional to the HCG concentration and confirms the pregnancy.

FPIA is a technique used to measure HCG levels during pregnancy diagnosis. It uses HCG-specific antibodies labeled with a fluorescent molecule. When HCG is present in the pregnant woman’s sample, the polarization of the fluorescent molecule changes, which can be measured to determine the HCG concentration and confirm pregnancy.
