Pharmaceutical Statistics, Volume 24, Issue 5, September/October 2025.ABSTRACT For toxicology studies, the validation of the concurrent control group by historical control data (HCD) has become requirements. This validation is usually done by historical control limits (HCL), which should cover the observations of the concurrent control with a predefined level of confidence.

Journal of Clinical Laboratory Analysis, Volume 39, Issue 16, August 2025.The six sigma model can objectively assess the analytical performance of plasma proteins. Different control concentrations yield different sigma values, which are visually displayed through standardized sigma performance verification charts. The six sigma model enables the development of personalized quality control strategies for each assay.
