- Abstract
Objective: Presentation an advanced method for deriving correct permissible precision limits which are required for the correct use of control charts, and for the effective internal quality control management (IQC) in a laboratory practice. Method: The 3-signal table application designed by Haeckel and Wosniok [1], which provides appropriate means to calculate the correct permissible precision limits (pCVA) from the empirical biological variability (CVE), based on reference intervals (RIs); the subsequent proper use of pCVA in the control charts. Discussion: Potential uses of the 3-signal table [1]. Conclusion: Warning against an improper use of the control charts; the correct method for deriving the permissible intermediate precision limits as the key ingredient for setting up effective control charts, which are a prerequisite for an objective classification of different laboratory methods according to their real quality.
