title: Design and demonstration of a quality assurance program for labor-intensive analytical systems.
abstract: An interlaboratory quality assurance program was designed and implemented for the analysis of serum for polychlorinated biphenyls (PCBs) and polybrominated biphenyls (PBBs). The two primary means of quality control were analysis of known and blind quality control samples and analysis of blind duplicate serum samples.
