Kidney Biopsy

Specimen Collection Criteria

Collect: A minimum of 3 portions of tissue are required to complete all kidney biopsy procedures. One portion should be placed in each of the following solutions:

  1. Dubosq-Brazil Fixative (DB) for in-house biopsy or Zinc formalin for outside biopsy, for light microscopy studies.
  2. FA Buffer for immunofluorescence studies.
  3. Glutaraldehyde for Electron Microscopy studies.

Collection Notes

  • Specimen container must be labeled properly with the patient's full name (first and last), date of birth, hospital number including visit, and specimen source.
  • Each specimen must be accompanied by a Beaumont Laboratory Form #6624, Progress Notes Operative Form #5113 and/or Anatomic Pathology Form, including the patient's full name, date of birth, patient's social security number (only last 4 of SSN), hospital number including visit number, surgeon and/or clinician name, specimen source (including the size), pre-op diagnosis, and a brief pertinent clinical information.
  • The time specimen was placed into fixative must be written on container and requisition. The specimen must be delivered to Surgical Pathology immediately since the timing of fixation must be controlled.

Physician Office/Drawsite Specimen Preparation

  • Arrange for transportation to the Laboratory prior to specimen collection. Specimen must be sent to the Laboratory immediately after collection in appropriate containers, as described above.
  • Specimens can be picked up by a Beaumont Laboratory courier and may also be sent via a courier/transportation service chosen by the facility sending the specimen. Please contact Surgical Pathology prior to sending the kidney biopsy at (248) 898-9042.

Preparation for Courier Transport

Transport: Biopsy specimens prepared as described above, at room temperature (20-26°C or 68-78.8°F). Specimens are hand delivered to Surgical Pathology.

Rejection Criteria

  • Any missing information will delay processing and final diagnosis.
