Specimen Reception

Specimens for histopathological diagnosis are sent to histology laboratories either during or soon after a surgical operation. The specimens come from hospital operating theatres and also from the surgeries of general practitioners (GPs) in the community. GPs usually only send small biopsies, such as skin or colposcopy biopsies of the cervix. Specimens received from hospital theatres may be from any part of the body and may be tiny biopsy samples or whole limbs or organs.

All specimens should be accompanied by appropriate paper-work which names the patient and gives their age and date of birth as absolute minimum identity checks. Preferably the patient's postal address and some kind of unique registration number (such as a hospital number or, in the UK, an NHS number) should also be included. Immediately upon receipt of a specimen, this paper-work is checked by a member of the laboratory staff. All details should match those written on the specimen container.

After the patient details have been checked, the specimen may be accepted for examination and the details are usually transferred to a computer database. In some laboratories a 'day-book' or ledger is still used. In either case, a unique specimen number will be assigned to the case at this stage as it often happens that different patients of the same name are having their cases processed at the same time. Along with the patient details, details of the specimen itself are also recorded. These specimen details should also have been included in the paper-work and should include the nature of the material (eg. skin, bone, liver) as well as the site of it's location in-vivo (eg. left flank) and also the reason for the investigation (eg. suspected carcinoma).

Once the specimen and paper-work have been matched and "booked-in" to the system they are labelled with the unique case number assigned earlier. The case is now ready for "cut-up".
