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 ValuesA 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.

A urine pregnancy test detects hCG, or human chorionic gonadotropin.
Pregnancy tests measure the level of hcg in your body. When you are pregnant, and as your pregnancy progresses, your hcg level rises. When you take a urine pregnancy test and it comes back negative, the level of hcg is not high enough to register on the test. When the quantitative serum pregnancy test is positive, it is a more acurate reading of how far along in your pregnancy you actually are.
A serum pregnancy test is a blood test performed in a physician's office or laboratory to get quantitative hCG. A "triple screen" is a blood test for hCG, AFP, and uE3. The other type of pregnancy test is an over-the-counter test which examines urine for the presence of hCG.
Ethanol is another word used to describe alcohol and quant would be a shorthand word for quantity. Hcg's formal word is Human Chorionic Gonadotropin, and qual is another shorthand term meaning qualitative. Those are test results expressed in terms of the presence or absence of a property or condition. Both of these tests require urine.
Nothing. It comes as pregnancy negative. Pregnancy test relies on the presence of Beta HCG in the urine for the detection of pregnancy. It is absent in normal healthy male.
There is a hormone that can be traced in your urine when you are pregnant, and that is called the HCG hormone. Advanced pregnancy tests can detect this hormone & what percentage of the HCG hormone that is in your urine.
hcg
When a human female is pregnant, she starts to generate a hormone called hCG (human choriogonadotropin). It is specific to a pregnant female as it is made in the placenta, and it is excreted in the urine. Most labs will run an hCG test on all urine samples as part of the standard urinalysis.

hcg
Get pregnant. Or extract it from a pregnant woman's urine.
hCG in urine is often indicative of pregnancy. They would have circled it because of the possible issues with certain medications/treatments during pregnancy.
'Hcg' means hormone produced early in pregnancy by the placenta; detection in the urine and serum is the basis for one kind of pregnancy test
pregnancy test
A urine pregnancy test detects hCG, or human chorionic gonadotropin.
The presence or absecne of HCG (human chorionic gonadotropin) can be measured in both the urine and in blood. Quantitative analysis (showing the rising levels of HCG as pregnancy progresses) can only be done in blood.
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
