- The Anatomic Pathology Laboratory must be notified at least 12 hours before the planned procedure 248-471-8247.
- The specimen must arrive in the Anatomic Pathology Laboratory by 12:00 p.m. to allow for clerical processing and shipment to the reference laboratory.
- Specimen(s) must be accompanied by a properly completed Pathology Requisition Form, Clinical Data Sheet and Patient Information Sheet provided by Nephropath (Arkana).
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:
- Dubosq-Brazil Fixative (DB) for in-house biopsy or Zinc formalin for outside biopsy, for light microscopy studies.
- FA Buffer for immunofluorescence studies.
- Glutaraldehyde for Electron Microscopy studies.
- 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.
Collect: Kidney biopsy tissue. The surgeon or pathologist will separate the specimen for processing. This is the surgeon’s choice:
- If the pathologist is performing the separation, the specimen is to be submitted fresh, in a properly labeled container, on a saline dampened Telfa.
- If the surgeon is performing the separation, bring a fresh specimen in a properly labeled container, on a saline dampened Telfa, to Histology where a pathologist or pathology assistant will assist the alloquation. OR, if preferred, obtain a renal kit from Histology before the procedure and complete the separation at bedside.
Specimens must be delivered fresh (without fixative), STAT, to the Anatomic Pathology Laboratory.
Physician Office/Draw 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.
- Any missing information will delay processing and final diagnosis.
- Specimens placed in fixative and/or an improper solution.
- Specimens not accompanied with required paperwork described in Instructions above.
Inpatient Specimen Preparation
- Farmington Hills: A Cytotechnologist or trained Laboratory Assistant is called to the procedure site with a microscope cart to assist a pathologist to view the specimen under microscopic examination to determine whether there is sufficient renal cortex in the specimen for further examination. The pathologist records his/her initial impression and guides the radiologists as to the necessity of additional core biopsies to ensure an adequate specimen is obtained. The pathologist divides up the core biopsies according to the instructions in the kit. A minimum of one piece is submitted into each zinc formalin, FA buffer, and Glutaraldehyde. The specimen must be delivered to Surgical Pathology immediately by the Cytotechnologist or trained Laboratory Assistant along with paperwork where arrangements for courier transport to Royal Oak are handled.
- Grosse Pointe: Pathologist's Assistant is called to Ultrasound to assist in placing specimens in correct containers/fixatives as instructed in the biopsy kit. A minimum of one piece is submitted into each zinc formalin, FA buffer, and Glutaraldehyde. The specimen must be delivered to Surgical Pathology immediately by the Pathologist's Assistant. Paperwork and the specimens are taken to Specimen Reception where arrangements for courier transport to Royal Oak are handled.
- Royal Oak: Electron Microscopy Laboratory technologists assist doctors during a kidney biopsy by dividing the biopsy into 3 sections according to instructions provided in the biopsy kit. A minimum of one piece is submitted into each DB fixative, FA buffer, and Glutaraldehyde. The specimen must be delivered to Surgical Pathology immediately.
- Troy: A Cytotechnologist is called to Ultrasound to assist in placing specimens in correct containers/fixatives as instructed in the biopsy kit. A minimum of one piece is submitted into each zinc formalin, FA buffer, and Glutaraldehyde. The specimen must be delivered to Specimen Reception immediately by the Cytotechnologist along with paperwork where arrangements for courier transport to Royal Oak are handled.
Specimens in Dubosq-Brazil Fixative (DB) must be transferred to 10% Neutral Buffered Formalin within 4 hours of collection. Outside biopsy specimens should be left in Zinc Formalin for 6 hours before processing.
Histology staff will prepare the kit for transport to Nephropath (Arkana) Laboratory.
Specimen Stability for Testing:
Specimens are processed immediately upon receipt in the Laboratory.
