Pregnancy

Beta hCG test

Also called hCG, pregnancy blood test, b-hcg

The pregnancy hormone made by the placenta.

Typical range
Not pregnant: below 5 mIU/mL. In early pregnancy it roughly doubles every 2–3 days (Clarilab shows the doubling time).

Why it's done

Confirms pregnancy. Repeated 48 hours apart in early pregnancy to check it is rising as expected.

What a high result can mean

Normal in pregnancy; rises fast in the first weeks. Very high values can mean twins or, rarely, a molar pregnancy.

What a low result can mean

A slow rise or fall can mean an early loss or an ectopic pregnancy; your doctor will advise.
