Serum beta hCG
Informed by recognized medical guidance
Overview
Serum beta hCG is a blood test that measures the level of a hormone called human chorionic gonadotropin. This hormone is made by cells in the placenta during pregnancy and can also be produced by some types of tumours. The test is often used to confirm pregnancy, monitor a pregnancy that might be at risk, or help diagnose certain cancers.
Key facts
- Serum beta hCG levels rise quickly in early pregnancy and can be detected about 10 days after conception.
- The test is also used as a tumour marker for some cancers, such as testicular, ovarian, or germ cell tumours.
- Low or falling levels of beta hCG in pregnancy may suggest a miscarriage or ectopic pregnancy (pregnancy outside the womb).
Yes, this is a very common blood test. It is routinely used to confirm pregnancy and is also used in cancer care, though less frequently.
It primarily affects women of childbearing age who may be pregnant, but it is also used in men and women of any age to help detect certain types of cancer.
