Fresh Tissue Collection and Submission

All specimens sent to the laboratory as "fresh" samples must be submitted according to the specifications below.

Renal Biopsy

We will also accept muscle biopsies previously frozen by trained personnel for additional testing or consultation. Please contact the lab for further instructions.

All Other Tissue for Immunofluorescence (IF)

The laboratory prefers to receive tissue for IF testing fresh, according to the directions below. Submission in Michel's medium will cause staining artifact and slows processing turnaround time.

All fresh samples can be processed for paraffin, immunofluorescence, and electron microscopy, or any combination of the aforementioned options.
