Purpose and Scope

In pathology the properly chosen and prepared tissue specimen furnishes diagnostic evidence, records and changes produced by a given disease, and preserves the relationship of the tissue elements as they existed in life. After choosing the best sections of tissues, it is equally important that proper fixation be completed. Embedding tissue in paraffin blocks, proper preparation of microslides, and furnishing complete information on the forms submitted by hospitals and laboratories are essential if a case history is to be of value to the patient and the medical profession. The methods described in this manual will assist personnel of contributing activities in the preparation, storage, or shipment of microslides, paraffin blocks and wet tissue to histopathology centers, references laboratories and/or the Armed Forces Institute of Pathology (AFIP). These methods should establish procedures to eliminate waste and prevent loss of valuable material through improper preparation, storage or shipment. This manual has been prepared for reference purposes and it includes supply lists to assist personnel in securing both standard and nonstandard items.
