Our Tissue Archive Service in the Department of Pathology

The Tissue Archive Service (TAS) was established within the Department of Pathology at The Ohio State University Wexner Medical Center in June 1998 to serve as the custodian of diagnostic archival formalin fixed paraffin embedded tissues and corresponding hematoxylin and eosin stained slides. Since its creation, specimens have been organized and policies have been instituted for the use of diagnostic archival tissues in research, clinical trials, case studies and teaching primarily by Ohio State investigators, physicians, residents and fellows, as well as routine requests for copies of the diagnostic slides by attorneys.

In September of 2007, the Tissue Archive Service became the point of contact for investigators at Ohio State's Wexner Medical Center to drop off research specimens. TAS is also the point of contact within Ohio State's Wexner Medical Center, Department of Pathology for requests for medical devices and foreign objects from surgery received by Ohio State's Pathology Gross Room.


Requests for use of diagnostic slides or block tissue for research, clinical trials, case studies, teaching and legal purposes are received by TAS and are processed based on the type of request. Requests for diagnostic slides or blocks relating to patient care are placed with the relevant clinical groups within pathology (Pathology Information Office, OSU East Pathology Office, Renal Pathology Office, Neuropath Office and Cytology Office). TAS staff work directly with these areas in pulling and providing specimens for patient care purposes. Research requests require IRB approval. For assistance in placing orders contact:



Due to the variety of tissue archive services available, price quotes are developed on a case-by-case basis.

Checks are accepted, but TAS currently does not accept credit card payments.

External clients are asked to provide checks as the means of payment. Clinical trial orders relating to patient treatment and legal orders related to court orders are processed and material is released prior to receipt of payment (an invoice is provided). For all other external requests, an invoice is created and payment is received before processing the request.

Diagnostic Slides

Diagnostic slides are not released from pathology by Tissue Archive Service. Tissue blocks may be released for patient consented clinical trials and research studies if tissue use guidelines are met and there is patient consent. Tissue blocks are forwarded to the Pathology Core Facility (PCF) lab within the Human Tissue Resource Network for processing.

Typically, review and use of diagnostic slide specimens for research purposes involve a collaboration with an Ohio State pathologist. Original diagnostic slides are reviewed by Ohio State pathologists or pathology residents and remain physically within the Department of Pathology.

Digital images of slides can be provided by request. Contact Pathology.TAS@osumc.edu for fees and processing instructions.
