title: Validating the performance of QC procedures.
abstract: A methodology for computing the maximum expected number of unreliable patient results produced because of an out-of-control condition for a given quality control strategy is presented along with strategies for changing the expected number of unreliable results produced and reported. The expected number of unreliable patient results reported before and after the last accepted quality control evaluation before the detection of an out-of-control condition are discussed and used as design criteria for quality control strategies that meet a laboratory's risk criteria.
