ABSTRACT
The national standard of laboratory quality control is based on a assumption about normal distribution of random error. The data of procedure of quality control get from analyzer Flexor XL during three months period were examined. The distributions of random error were non-Gauss ones in almost half of all examined tests by reason of both abnormal asymmetry and excess. To prevent possible clinical mistakes the actual level of quality is to be evaluated using dynamic values of bias, variation coefficient and o-metrics based on simple consecutive means. The most appropriate time of averaging consisted about 10 days and had no dependencies of type of test. The actual standard cab y easily improved taking into account the discovered advantages and simplicity of proposed approach.
