Method for the Evaluation of Uncertainty in Biological Sample Analysis Laboratory and Its Applications in Laboratory Quality Control / 中国药房

ABSTRACT

OBJECTIVE:To provide a way to evaluate test capability for biological sample analysis laboratory,so as to im-prove this test quality. METHODS:By analyzing the use of measurement uncertainty in China and detailing the steps of biological sample analysis laboratory measurement uncertainty,the effects of measurement uncertainty on biological sample analysis laborato-ry are illustrated from two aspects of inner and outer quality control. RESULTS & CONCLUSIONS:National laboratories mainly examine the source of uncertainty through establishing mathematical model,and then uncertainty is evaluated. Uncertainty evalua-tion is a continuous process. Uncertainty assessment and assurance is the overall situation in a biological sample analysis laboratory quality control. Thus,biological sample analysis laboratory can find a method of self-testing capabilities by uncertainty evaluation, find the maximum uncertainty and eliminate or reduce it gradually,ultimately improve laboratory testing quality.
