Renal Biopsies

Cellular Pathology


Two types of renal biopsy can be sent for histopathology investigation: diagnostic/native biopsies and transplant biopsies.  In order for comprehensive investigations to be carried out, native biopsies should be sent in saline and transplant biopsies should be sent in neutral buffered formalin.

Renal biopsies must be pre-booked by contacting the histopathology laboratory ext. 2930.

If you require a result on the same day, the biopsy must be received within the laboratory by 12pm.

If you require a result on the following day, the biopsy must be received within the laboratory by 4pm.

Please note: 

  • Specimens must be sent immediately to the laboratory in saline and handed personally to a member of the histology department. They must not be left at specimen reception.
  • Biopsies received in formalin are not suitable for Immunofluorescence (IMF) studies.
  • Transplant biopsies should be sent in fixative, however if IMF or Electron Microscopy (EM) studies are required they should be treated as routine renal biopsies and sent immediately to the laboratory in saline.
  • Specimens suspected or known to have Covid-19, Hepatitis B or C, HIV/AIDS or nvCJD will not have IMF performed.  Please submit these specimens in formalin.
