The Histocompatibility/Identity Testing Committee would like to remind all laboratory directors that they must request that qualified expert inspectors in specific specialty areas be appointed to inspection teams that will be doing the biennial on-site inspections. Lists of qualified inspectors for histocompatibility, cytogenetics, and molecular pathology are included in the Inspector’s Inspection Packets, and are available from the Laboratory Accreditation Program at the CAP office in Northfield, Illinois.
