Drug test. For other uses, see Drug testing (disambiguation). A drug test is a technical analysis of a biological specimen, for example urine, hair, blood, breath, sweat, or oral fluid/salivaâto determine the presence or absence of specified parent drugs or their metabolites.
All pregnancy tests work by detecting the presence of human chorionic gonadotropoin (hCG), the pregnancy hormone. In both urine and blood pregnancy tests, the presence of the hormone human chorionic gonadotropoin (hCG) is evaluated. The hCG hormone is usually only present in blood or urine if a woman is pregnant. When an egg fertilized with sperm is implanted in the uterus of the woman the hCG is then produced.
