Quality control goals for quantitative clinical chemistry assays are reviewed. Recommendations for clinically useful limits (CUL) criteria as minimally acceptable +/- 2 SD for run-to-run and/or day-to-day technical reliability are presented in terms of biologic variations for different levels and clinical applications. A review of the literature and the questionnaire response of a medical school staff presented in this study reveal striking agreement of acceptable analytic goals based on physicians' opinions, biologic variation, and practical analytic feasibility. The current state-of-the-art in clinical laboratories can approach excellence because actual within-laboratory 2-SD variability estimates are somewhere between acceptable CUL criteria and twice as good. Assessing the reliability of laboratory reports based on accuracy and precision or total analytic error is also discussed.
