pregnancy test
A urine pregnancy test detects hCG, or human chorionic gonadotropin.
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.
Hello there. Yes you may very well be pregnant. A pregnancy test will only turn positive once HCG has been found in your urine. BUT there needs to be ENOUGH HCG in your urine to make a positive test result. Depending on the pregnancy test, they usually look for 5MIU - 50MIU. If you had 49MIU of HCG in your urine and did a test that looks for 50MIU it would be negative. The same thing applies to the Labatory urine pregnancy test. When they did the test you probably didn't have enough HCG in your urine to give you a positive. You need to have a blood test. Urine tests are NOT reliable and give negative results when women are indeed pregnant. See your doctor for a Quantitative Beta HCG pregnancy test. Good luck.

A pregnancy test, either blood or urine detects the hormone hCG.
That depends.. on certain hCG test. It is recommended to read the manual of your urine pregnancy test. Some test accept blood/serum, but some test do not.
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
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.
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.
Gravindex is a type of pregnancy test, which uses urine to detect HCG. Urine pregnancy tests are now around 97% precise.
