Human Chorionic Gonadotropin (hCG) is a hormone produced by the placenta during pregnancy that supports the development of the fetus. This test measures hCG levels in the blood and is primarily used for early pregnancy detection, typically within one week after conception. hCG levels rise rapidly in early pregnancy and can help confirm pregnancy, estimate gestational age, and monitor pregnancy health. Abnormal hCG levels can indicate various pregnancy complications including ectopic pregnancy, threatened miscarriage, or multiple pregnancies. Elevated hCG levels in non-pregnant individuals may suggest certain types of cancer, particularly germ cell tumors, trophoblastic tumors, or other malignancies. This test is commonly ordered when confirming pregnancy, evaluating pregnancy complications, or when certain cancers are suspected. Regular monitoring of hCG levels during early pregnancy is crucial for ensuring healthy fetal development.
Patient Prep
Avoid biotin supplementation for 72 hours prior to testing.
