Pregnancy test

A pregnancy test is used to determine whether a female is pregnant or not. The two primary methods are testing for the female pregnancy hormone (human chorionic gonadotropin (hCG)) in blood or urine using a pregnancy test kit, and scanning with ultrasonography.^[1] Testing blood for hCG results in the earliest detection of pregnancy.^[2] Almost all pregnant women will have a positive urine pregnancy test one week after the first day of a missed menstrual period.^[3]
