A quantitative human chorionic gonadotropin (HCG) test measures the specific level of HCG in the blood. HCG is a hormone produced during pregnancy. See also: Qualitative HCG test Alternative Names
Serial beta HCG; Repeat quantitative beta HCG; Human chorionic gonadotrophin blood test - quantitative; Beta-HCG blood test - quantitative; Pregnancy test - blood - quantitative How the test is performed Blood is drawn from a vein, usually on the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic, and an elastic band is placed around the upper arm to apply pressure and restrict blood flow through the vein. This causes veins below the band to swell with blood. ![]() A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the band is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding. How to prepare for the test No special preparation is necessary. How the test will feel When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing. Why the test is performed HCG appears in the blood and urine of pregnant women as early as 10 days after conception. Quantitative HCG measurements can precisely predict the age of the fetus. This test is also done to diagnose abnormal conditions that can raise HCG levels.
