1. A lab when specifically testing for anything usually knows within a few hours. The exception is if they have to grow a bacteria/virus/fungus in a dish and incubate it. Then it takes a few days. If they're testing specific of an enzyme, they usually know within a day or 2 of testing. Check with your doctor. By the way, if it's bad news, they usually contact you. The longer the wait from the time of your blood test to the time you get the results, the better the results are.
