The introduction of immunoassay to laboratories where environmental changes and limited equipment are likely to limit reliability and precision have emphasized the need for routine evaluation of assay performance. The aim has been to provide both an accurate calibration of the immunoassay response and an assessment of assay error which will allow the assayist to monitor and improve assay performance. As models of immunoassay error are used at all stages of processing they are described in some detail. Analysis of sources of error associated with counting, small perturbation “experimental” errors and assay “drift” is explicitly embraced by the program and is used to screen out untypical assay errors or “outliers”. This is a statistically more reliable estimate of precision than the observed replication for an individual result and when calculated for doses over the working range of the assay yields the precision profile as an important indicator of assay performance.
