How soon can a blood test detect pregnancy?

Soon. You can get a blood test with same day results and they can be reliable 1 to 2 days before your missed menses. I do not like to do pregnancy tests too early. Several women have biochemical pregnancies that do not grow and get a normal period 1 to 2 days later. So, my suggestion is that you do your blood test when you miss your period.
