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.
