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.
How long does it take for a testosterone blood test results to come in and is it a specialty test? The answer to this question depends almost entirely on the laboratory that is performing the test, so I recommend that you speak with your doctor. The testosterone test itself is not all that long, it probably only takes a few hours at most. However, the question is how often does the lab run the test. For some of the specialty tests, they only get run once a day and sometimes less.
