Pregnancy test facts medically edited by: Charles Patrick Davis, MD, PhD Pregnancy tests work by detecting a hormone in a woman's blood or urine: hCG (human chorionic gonadotropin) is produced when an egg implanted in the uterus.
A pregnancy test attempts to determine whether a woman is pregnant. Markers that indicate pregnancy are found in urine and blood, and pregnancy tests require sampling one of these substances. The first of these markers to be discovered, human chorionic gonadotropin (hCG), was discovered in 1930 to be produced by the syncytiotrophoblast cells of the fertilised ova (eggs).
Home Pregnancy Test Overview If you think you are pregnant, you may want to test yourself at home with a home pregnancy test. You can buy test kits at a drug store without a prescription. Home use kits measure a hormone called human chorionic gonadotropin (hCG) in your urine.
Home pregnancy tests can find the presence of a pregnancy hormone (called human chorionic gonadotropin, or hCG) in a sample of urine. High levels of hCG are made during pregnancy. The home tests have similar results to the pregnancy tests done on urine in most doctors' offices if they are used exactly as instructed.
