title: [Statistical quality control of clinical laboratory analyses using Chi squared criterion (use of computer modeling)].
abstract: Models of analytical series simulating good results and series with systematic errors were created on the basis of data bank of results of clinical biochemical analyses by computer simulation method. The quality of analyses was evaluated using chi 2 test. This parameter reacts to slight systematic errors and depends little on changes in the examined patient population; on the other hand, its sensitivity is the higher the longer is the analytical series. Statistical method for quality control by the chi 2 test is highly sensitive, absolutely objective, and requires no extra expenses for control studies.
