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.
This hormone is released after the fertilized egg attaches itself to the wall of your uterus, while its amounts increase as the pregnancy progresses. How soon a pregnancy test will be able to detect this hormone depends on its sensitivity because some are able to detect HCG only when released in large enough amounts. As a result, a pregnancy test that is not able to detect small amounts of HCG will give you a negative result if you take it too soon.
