​Medical Renal Biopsy

Histology - Anatomic Pathology

Specimen Requirements​ ​

  • Leak-proof specimen container
​Collection Procedure
  • ​Renal biopsies must be booked in advance to ensure technologists are available to process the specimen.  Call 655-8569. You will need patient’s name, date and time of collection and hospital where the specimen will be procured.
  • If biopsy is cancelled, please call 655-8569
  • Label container with patient’s first and last name, personal health number (PHN)
  • The removed biopsy should be placed on saline soaked gauze (or Telfa™ pads soaked with Normal Saline) in leak-proof labelled specimen container. Fold the gauze or Telfa™ pad over the biopsy pieces to avoid drying of the specimen. Please avoid filling the container with liquid of any sort (saline, RPMI, etc.); this causes the biopsy pieces floating inside the container and may subsequently lead to loss of tissue and considerable processing artifacts.
  • Place specimen container in a plastic bag containing crushed ice
  • Complete a Surgical Pathology Requisition Form #4030 with the patient’s addressograph, site of biopsy, all relevant clinical history and physician’s signature
