How much time does it take for a testosterone blood test results to come in and is it a specialty test?

Depends . . .: Some local labs are large enough that they have the equipment to measure Testosterone in their own facility w/o sending out your blood sample to an outside specialty facility. In this case, turn around time might be just a few days. If your lab is too small to run its own T measurement equipment, then it might take a week or more to get your results back. Ask your doc & local lab for details.
