Human Chorionic Gonadotropin (HCG)
Why It Is Done
A test for human chorionic gonadotropin (hCG) is done to:
- See whether you are pregnant.
- Find an ectopic pregnancy.
- Find and check the treatment of a molar pregnancy.
- See whether there is an increased chance of birth defects such as Down syndrome. The test is used in combination with other screening tests.
- Find and check the treatment of a cancer that develops from an egg or sperm (germ cell cancer), such as cancer of the Reference ovaries Opens New Window or testicles. In such cases, a test for alpha-fetoprotein may be done along with a test for hCG.
