Specimen Requirements

Specimen: Tissue

Collection Container: Preferred: 10% Formalin filled vial

Specimen Processing: Biopsy specimens should be placed in a 10% buffered formalin specimen container. All tissue submitted to the laboratory from the Operating Rooms should be received fresh (without fixative) between the hours of 7:00 am and 4:00 pm, Monday through Friday.  Outside these hours, tissue should be submitted in 10% formalin or refrigerated if the specimen size (i.e. limbs) does not allow fixation.

Specimen Transport: Within UWHC pneumatic tube station 832 or hand delivered to UWHC Surgical Pathology Specimen Receiving (C7/350) depending on specimen size.


Tissue specimens must arrive in UWHC Surgical Pathology Specimen Receiving Room (C7/350) by 3:30 pm, Monday through Thursday only, to be prepared for interpretation the following day. Some specimens, due to their size or special processing requirements, require longer turnaround times.


Tissue received on Friday will routinely be prepared for interpretation on the next working day (usually Monday).


Situations may exist that would require results prior to the routine turnaround time. The attending physician should consult with the on-duty Surgical Pathologist to evaluate the circumstances and make arrangements for non-routine processing.

Test Limitations:

Normal laboratory hours are Monday through Friday, 7:30 am - 4:00 pm. Outside normal hours, the Surgical Pathology resident-on-call should be contacted. The call list is available in the OR call schedule book, the UWHC message center (608)262-2122, or online at the UConnect Web Paging link.

Additional Information:

Specimens obtained on patients with life threatening infections or transplant patients whose organs may be undergoing rejection can be processed and interpreted the same day they are obtained. Specimens that require special processing must meet certain criteria and be hand delivered to UWHC Surgical Pathology Specimen Receiving (C7/350)by 12:00 noon to be processed and interpreted the same day. This processing is offered Sunday through Saturday. Specimens in this category should be rare and may require the approval of the assigned Surgical Pathologist. The Pathologist can be contacted via the UWHC message center (608)262-2122, or online at the UConnect Web Paging link.
