Limitations

The detection of hCG in urine or blood within 3-4 weeks of the last menstrual period is the most reliable indicator for the confirmation of pregnancy. hCG is initially secreted by the trophoblast, and later by the chorion and placenta. Levels rise exponentially to a peak during the first trimester, declining to a plateau during the second and third trimesters. Measurement of hCG has also been applied in the diagnosis of ectopic pregnancy, threatened abortion, and multiple gestation.

Reference Range

Negative

Clinical Significance

Human chorionic gonadotropin (hCG) concentrations of 25 mIU/mL andgreater can be detected by this method. In normal pregnancy, hCG levelscan reach this as early as 7 to 10 days post conception. Elevatedlevels of hCG may be found in trophoblastic disease, some carcinomas,ectopic pregnancies and hydatidiform moles.
