Varies: As a general rule, 24-48 hrs, but if there are cultures pending or special stains needed it may take longer. Usually preliminary results are available within a day, but complete testing can be prolonged. Sometimes pathologists may send tissue to reference labs for confirmatory diagnoses or second opinions.

~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.
