[Standardization of laboratory data: verification of inter-laboratory data variations].
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 in clinical laboratory testing and recommendation methods for laboratory test and/or standard materials are proposed. The Japan Society for Clinical Chemistry established guidelines to determine the activity of serum enzymes and other materials. JCCLS established a new project, the Committee for Investigation of Standardization of Laboratory Testing. It has three columns and column two is the verification of inter-laboratory variations. Sixteen institutions in 2004 and 40 in 2005 were enrolled in this program. The current inter-laboratory variations are discussed.
