HCG in urine

Definition:

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

Other HCG tests include:



Alternative Names:

Beta-HCG - urine; Human chorionic gonadotropin - urine



How the test is performed:

To collect a urine sample, you urinate into 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 best. This is because urine is the most concentrated and has enough HCG to be detected.



How to prepare for the test:

No special preparation is needed.



How the test will feel:

The test involves urinating into a cup or onto a test strip.



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.



Normal Values:
  • The test is negative if you are not pregnant.
  • The test is positive if you are pregnant.

A pregnancy test, including a properly performed home pregnancy test, is considered to be about 98% accurate. Positive results are more likely to be accurate than negative results. When the test is negative but pregnancy is still suspected, the test should be repeated in 1 week.



What the risks are:

There are no risks, except for false positive or false negative results.
