A home-based assay designed to detect the presence of human chorionic gonadotropin (hCG) in urine, a hormone produced during pregnancy. These tests employ either blue or pink dye to indicate a positive or negative result, with the color change signifying the presence or absence of sufficient hCG levels. A single line often indicates a negative result, while two lines generally indicate a positive result. The intensity of the lines can vary depending on the concentration of hCG.
The availability of rapid, accessible pregnancy tests has significantly impacted reproductive healthcare. This technology offers individuals the convenience of early detection, allowing for prompt initiation of prenatal care if desired. Historically, confirmation of pregnancy relied on clinical examinations, which were often delayed. The advent of readily available urine-based tests has empowered individuals to make informed decisions about their reproductive health earlier in the pregnancy timeline.
