Risk-Based Intermediate Precision Studies for Analytical Procedure Validation
Validation of analytical procedures require assessment of the impact of variations within laboratories; however, guidance to study intermediate precision has been lacking. Science and risk-based principles should be used in the design of intermediate precision studies.
Validation of analytical procedures requires study of intermediate precision for within-laboratories variations; however, there is no global guidance on how to develop such designs. By applying science- and risk-based principles-aligned with quality by design (QbD)-to analytical procedures, studies can be designed to ensure the factors selected present the highest risk of impacting the performance of the analytical procedure. In addition, the number of independent analytical runs to include in these designs should be linked to the overall risk/complexity associated with the analytical procedure.
Useful pre-QbD guidance (provided by the Japanese National Institute of Health Sciences) proposed the use of a generic design which utilizes six independent analytical runs. Examples are provided which instead link the design structure and the number of independent analytical runs to the risk.
