Bio-Rad Laboratories has published the third workbook in its quality control (QC) focused series that offers PACE credits. The series is digitally interactive, enabling lab professionals to learn and pursue a higher standard in laboratory QC. The third installment, “Quality Control Process Optimization with Cost of Quality Application,” focuses on a practical approach to applying cost-of-quality initiatives to regular laboratory QC workflow. Users will be taught to identify and differentiate among prevention, appraisal, and failure costs in the laboratory and explain the difference between internal and external failure costs. Upon successful completion of a short exam at the end of the workbook, a certificate for 2.5 contact hours can be earned.
