Storage, Retention, and Use of Leftover Pathology Specimens: The Underestimated Treasures.

ABSTRACT

The proper regulations for storage, retention, and use of archived specimens in pathology laboratories and academic institutions are yet to be established. These specimens could be used appropriately for research purposes. Ideal storage and retention in a controlled environment is necessary, and there is a lack of established rules regarding the ownership of the tissue specimens, paraffin blocks, and slides. Though there are numerous uses of formalin-fixed tissue specimens, blocks, and slides, there are also problems in archiving them that hinder their use. This review article addresses the above issues and proposes simple guidelines for the effective use of archived specimens.
