The hormone human chorionic gonadotropin (hCG) is produced during pregnancy. This hormone is formed in placenta and it tends to nourish the egg after fertilization.
HCG tests are of two types:
Qualitative HCG test – This test detects presence of hCG in blood.
Quantitative HCG test (or beta hCG) – This test measures the amount of hCG actually present in the blood.

- Ectopic pregnancy
- Testicular cancer (in men)
