Both blood and urine pregnancy tests check for the presence of a chemical called human chorionic gonadotropin, which is produced during a pregnancy. Waiting two weeks post conception (one the first day of a missed period) is recommended, but positive results can be detected as early as one week after conception. After a pregnancy has been detected by a blood or urine test, your doctor will request an ultrasound to confirm that a live embryo is present. Ultrasounds can first be seen at five weeks pregnancy and an embryo and heart beat can be detected by six weeks.
How does a test tell if you are pregnant or not? A pregnancy test detects the presence of a hormone called human chorionic gonadotropin (hCG) in your blood or in your urine. hCG is produced in the placenta shortly after the embryo attaches to the uterine lining and builds up rapidly in your body in the first few days of pregnancy.
