HCG in urine - Overview

Alternative Names

Beta-HCG - urine; Human chorionic gonadotropin - urine

Definition of HCG in urine:

This type of human chorionic gonadotropin (HCG) test measures the specific level of HCG in the urine. HCG is a hormone produced during pregnancy.

How the test is performed:

As you urinate, collect a urine sample in a special (sterile) cup. Home pregnancy tests require the test strip to be dipped into the urine sample or passed through the urine stream while urinating. Carefully follow package directions.

Usually a first-morning sample (the first time you urinate in the morning) is preferred, because it is the most concentrated.

How to prepare for the test:

No special preparation is needed.

How the test will feel:

The test involves normal urination into a cup or onto a stick.

Why the test is performed:

Urine HCG tests are a common method of determining if a woman is pregnant. The best time to test for pregnancy at home is after you miss your period.
