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

Alternative NamesBeta-HCG - urine; Human chorionic gonadotropin - urine
How the test is performedAs 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 testNo special preparation is needed.
How the test will feelThe test involves normal urination into a cup or onto a stick.
Why the test is performedUrine 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 areThere are essentially no risks (except for "false positive" or "false negative" results).
Special considerationsDrugs that can decrease HCG measurements include diuretics and promethazine.
Drugs that can increase HCG measurements include anticonvulsants, anti-parkinsonian drugs, phenothiazine, and promethazine.

Human chorionic gonadotropin (HCG) in urine is a hormone produced during pregnancy. It is used in home pregnancy tests as a marker for confirming pregnancy. Elevated levels of HCG in urine can also indicate other conditions such as testicular cancer or ovarian cancer.

How it is possible for some one to test negative on a simple urine test and positive on the standard test?
It is possible if a person has recently used a drug that is detected by the standard test but not the simple urine test. The standard test is more sensitive and can detect lower levels of drugs or metabolites in the urine. Timing of drug use, metabolism rates, and the detection thresholds of the two tests can all contribute to this discrepancy.

The lab urine tests looks for the presence of HCG (a pregnancy hormone) in your urine. if you get a positive- the only way it's wrong is if you've taken HCG containing medications (for infertility treatments) or if you have a tumor that is producing HCG-very rare. if you get a negative- the test could be wrong if it was done too early after ovulation, you could be pregnant, but not producing enough HCG to show up in a test. ~pawsalmighty
