Pregnancy test (hCG)

Also called: hCG test, Beta hCG, Quantitative hCG

Pregnancy tests detect hCG, a hormone made after a fertilized egg implants. Urine tests are done at home; blood tests can measure exact levels.

SampleUrine or blood
Fasting?Usually not needed
ResultsMinutes (urine); hours to a day (blood)
Good to knowOne result rarely tells the whole story. Your provider looks at your results together with your symptoms, exam, and other tests.

What the test is

Home tests are most accurate from the first day of a missed period.

In early pregnancy, hCG usually rises quickly; repeat blood tests can check how a pregnancy is progressing.

Why it's done

  • A missed period or possible pregnancy
  • Before some medicines, X-rays, or surgery
  • Following early pregnancy or possible miscarriage or ectopic pregnancy

Getting ready and what happens

  • For home tests, use first-morning urine for the strongest result.

How the test is done

  • Urine: pee on the stick or in a cup.
  • Blood: a sample is drawn from a vein.

What the results mean

ResultTypical range for adults
Not pregnanthCG below 5 mIU/mL
Likely pregnanthCG above 25 mIU/mL

Normal ranges vary from lab to lab and can differ by age, sex, and pregnancy. Your report lists your lab's own range next to each result. A result a little outside the range is often not a problem.

Positive

Means you're likely pregnant. Start prenatal care and a daily prenatal vitamin with folic acid.

Negative but no period

You may have tested too early. Test again in a few days, or see your provider.

When a result needs quick action

Call 911A positive test with severe one-sided belly pain, shoulder pain, fainting, or heavy bleeding (possible ectopic pregnancy)

Questions to ask your provider

  • What do my results mean for me?
  • Do I need to repeat this test or have other tests?
  • When should I schedule my first prenatal visit?
  • Are my medicines safe in pregnancy?

Risks

A blood draw is very safe. You may have slight pain or a small bruise where the needle went in.
