What is the purpose of this test?
Order this hCG (Pregnancy) Blood Test, QL, which provides a positive or negative result depending on the presence or absence of hCG in a blood sample to determine pregnancy. Human chorionic gonadotropin (HCG) is a hormone produced during pregnancy by the placenta and found in the bloodstream. HCG is typically detected in the urine or blood within 10 to 11 days of conception (when a sperm fertilizes an egg). HCG is often called the pregnancy hormone because of its special role in supporting a pregnancy.
Once the placenta starts producing HCG, it triggers the body to create more estrogen and progesterone. Jointly with HCG, these hormones help thicken the uterine lining and tell the body to stop releasing eggs (menstruating). The proper balance of these three hormones maintains and supports the pregnancy.
The qualitative HCG blood test results will be reported as negative or positive.
- A negative result indicates that a woman is not pregnant.
- A positive result indicates that a woman is pregnant.
- In some cases, a result may report a test as indeterminate. This usually happens due to a small amount of HCG being detected in the blood, for example, very early in pregnancy or when a pregnancy has miscarried. In these cases, a retest will need to be performed. Individuals should contact their healthcare provider for further information regarding their results.
