All specimens must be accompanied by a detailed clinical history of the patient. The specimen must be submitted in the proper fixative or buffer solution, depending on the sender:

  1. GMC Operating Rooms: Send ASAP to Surgical Pathology in a tube of saline. Store in refrigerator until processed.
  2. GLH, GCMC, and GWV Operating Rooms: Place renal biopsies in RPMI and transport on ice to GMC Surgical Pathology Lab.
  3. All other outside sites will collect renal biopsies using the renal biopsy kit for processing as follows:
    1. Two pieces about 1 mm in length taken from each end of the glomeruli containing core are placed in 3% glutaraldehyde for electron microscopy.
    2. A segment of glomeruli containing core measuring 3-6 mm in length is placed in Michel's solution for immunofluorescent microscopy.
    3. A segment of glomeruli containing core measuring 8-10 mm in length is placed in formalin for light microscopy.
    4. Any additional cores should be placed in formalin.
