title: [Standardization and Quality Assurance in Laboratory Medicine].
abstract: The standardization of clinical laboratory and compatible clinical data is needed for accurate diagnosis in routine medical practice or medical care. An external quality survey program (EQSP) in clinical laboratory testing and recommendation methods for laboratory test and/or standard materials are proposed. Many megaEQSPs in Japan have problems, such as examination samples (matrix and spike materials in abnormal specimens) and valuation basis. Proposals for EQSP are being developed: EQSP with fresh blood, EQSP using internal quality control, and control serum using donated blood (MaCRM).
