Abstract

We have characterized the performance of a commercial two-site immunoradiometric assay for manual in vitro diagnostic measurement of plasma corticotropin from Scantibodies Laboratory. We compared the results with those of a similar commonly used assay from Nichols Institute Diagnostics that has recently been withdrawn from production. The lower detection limit, range of the standard curve, cross-reactivity, and intra-assay and inter-assay imprecision of the two assays are very similar. Measurement of clinical samples and a series of samples from an experimental subject demonstrate high correlations between the two assays. These factors, together with recent clearance by the United States Food and Drug Administration for manual in vitro diagnostic measurement, make the Scantibodies corticotropin immunoradiometric assay an appropriate replacement for the Nichols assay.
