  Answer     A blood test should be able to pick up the HCG in your blood at about 7 days after conception.     Some pregnancy tests say they can pick up â¦ HCG in your urine from about 7-10 days after conception, but most tests you have to wait to about 14 days-when your period is due.
At What Point Can a Blood Test Determine Whether or Not a Woman is Pregnant? Blood tests are able to detect pregnancy about 7 to 12 days after conception, making them a better option than most at home pregnancy tests. Unlike home pregnancy tests, they can also determine the level of hCG in your blood. This is particularly useful information for your doctor because it can help reveal information about specific problems commonly experienced during pregnancy.
