How long to find out about incision biopsy?

~48hrs. Most basic pathology results from a biopsy should be available in ~48hrs. The tissue needs to fix in formalin for a particular amount of time (6hrs-overnight) then be processed, slides made and stained, then interpreted. Each of these steps takes time. Additional staining or deeper cuts for furthe evaluation/markers may add another day before the full results are back.
