How the Test is Performed    Return to top

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    Return to top

No special preparation is needed.

How the Test Will Feel    Return to top

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

Why the Test is Performed    Return to top

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 Results    Return to top

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.

Risks    Return to top

There are essentially no risks (except for "false positive" or "false negative" results).

Considerations    Return to top

Drugs that can decrease HCG measurements include diuretics and promethazine.

Drugs that can increase HCG measurements include anticonvulsants, anti-parkinsonian drugs, phenothiazine, and promethazine.
