Specimen for histological examination must be clearly labeled with the patient's name, date of birth or MRN and must be submitted with a completed histology requisition.
All specimens must be submitted in a properly labeled contained that, as a minimum, includes the patient's name, date of birth or MRN and type/source of specimen.
All slides and cassettes submitted must be properly labeled with the accession number and patient's name. Use a #2 lead pencil or solvent-resistant pen (Secureline Marker II/SuperFrost HistoPrep Pen, black) for labeling.
Use an appropriately sized container so as not to distort the specimen. Ideally, the volume of formalin should be at least 10 times the volume of the specimen; for larger specimens, the entire specimen should at least be covered.
Containers and fixatives such as formalin and Michel's solution are available from the Histopathology Laboratory. In the event that a specimen cannot be placed in formalin, place it in a refrigerator in a clean container; specimens should not be allowed to remain more than eight hours without fixation.
Disposal of Specimens
Unless the department is advised otherwise, all specimens are destroyed after approximately eight weeks. Tissue blocks and slides are kept indefinitely, unless the patient directs otherwise.
