What is an antibody to hcg?

An antibody to human chorionic gonadotropin (hCG) is a type of protein produced by the immune system that specifically binds to hCG, a hormone primarily produced during pregnancy. These antibodies can be used in various medical applications, including pregnancy tests and monitoring certain medical conditions, such as tumors that produce hCG. The presence of hCG antibodies can also be utilized in research to study pregnancy-related processes or to develop immunoassays.
