Each different lab has it's own specific turn around time for test results. Typically, it is 24hrs for the blood test that you had done. Then it is a matter of how long it takes for your doctor to call you after receiving the results. Unfortunately, this is what usually takes the longest. I would wait 24 to 48 hrs after having the test done, then call your doctor. The squeaky wheel gets the oil first. Pester them a bit.
