What a biopsy kit contains:

• 3 vials containing formaldehyde, 2.5% glutaraldehyde fixative and Michel's transport medium
• Renal Pathology Requisition
• Renal Clinical History Form
• Biohazard Bag
• Prefilled, prepaid Fed Ex Airbills, for First Overnight Delivery
• Fed Ex shipping bags
• Fed Ex transport boxes
• Instructions for core distribution

Distribution of Specimen for Light Microscopy (LM), Electron Microscopy (EM) and Immunofluorescence (IF):
                                        Two cores of tissue

Electron Microscopy (EM) Specimen

• Place the 2, 1-2 mm cut pieces of kidney biopsy (cut from each end of a core) in the vial containing 2.5% glutaraldehyde fixative.
• Label with patient name, unique patient id# or date of birth and collection date.
• Be sure to wash off any excess fixative on the end of the blade with saline before touching the blade to another biopsy core.

Immunofluorescence (IF)

• Place the remaining the cut core in Michel's Transport Media or Immunoflourescence.
• Label with patient name, unique patient id# or date of birth and collection date.

Light Microscopy (LM)

• Place one remaining core in the vial of 10% buffered formalin. For a two-croe protocol, place the larger core in formalin.
• Label with patient name, unique patient id# or date of birht and collection date.
• Be sure to wash off any excess fixative on the end of the blade with saline before touching the blade to another biopsy core.

NOTE: If cores are of greatly differing lengths, take two 1 mm segments from each end of larger core for EM. Place smallest core (of the two after EM tissue removed) in Michel’s fixative and place largest core in formalin.

How to maximize your success in identifying glomeruli:
Place the tissue core on a glass slide and view with an ordinary microscope with 4X (occasionally 10X objective can be helpful but not really necessary). I find this much better than a dissecting microscope. Glomeruli will be seen as in figure below. One can also easily identify connective tissue and medulla.

Specimen Packaging

Fed Ex packaging guidelines for UN3373 shipments apply to the transport of a renal biopsy to the UIDL.  Anyone shipping a renal biopsy should be aware of all applicable guidelines and regulations. Senders are solely responsible for compliance.  See www.fedex.com and SEARCH 3373 for details. 

• Label containers with "Formaldehyde precaution".
• Use the 95kPa Specimen Transport Bag for the specimen containers with the requisition in the outside pocket of the bag.
• Place the double-bagged specimen into a box with adequate absorbent material in case of leakage.
• Securely seal the shipping container.
• Indicate on the exterior of the box "Formaldehyde Caution" and/or "Glutaraldehyde Precaution".
• Ship at ambient temperature. DO NOT FREEZE.
• Complimentary FIRST OVERNIGHT shipping via Fed Ex should ensure receipt in the UIDL by 8 am CST M-F and same day results.  Specimens are also received on the weekend with STAT services available.

NOTE:  SATURDAY DELIVERIES
Mark airbill for Saturday Delivery and Priority Overnight and affix “SDR” label on the outside of FedEx ClinPak to ensure proper delivery.  Saturday deliveries not properly marked will NOT be delivered until Monday or later.
