The home pregnancy testworks by measuring human chorionic gonadotropin (hCG) hormone in urine. This hormone was initially studied in NICHD intramural laboratories as a reliable marker of certain tumors. Refinement of the assay for hCG detection to enhance specificity enabled its ready application to pregnancy detection.
