Calcitonin (CT) is one of the most recently discovered calcium-regulating hormones; the first brief allusion to its existence appeared in 1961.1 The first assays for CT were based on its hypocalcemic property upon injection into rats.2,3 Radioimmunoassays for animal calcitonins soon followed, but the availability of sensitive radioimmunoassays for human CT (hCT) awaited determination of the amino acid sequence synthesis of the hormone.4 There are now well over 20 published radioimmunoassays for human CT that vary in such basic elements as antisera, buffer constituents, incubation conditions, and tracer preparation; sensitivity and final results also vary.
