title: A simple computer programme for standard curve tracing and calculations in RIA following sigmoid patterns.
abstract: A computer programme is described for the analysis of radioimmunoassays assuming a general sigmoid shape. The mathematical treatment uses the results obtained from a sigmoid equation to perform a limited operational search in order to optimize the fitness of the curve. The programme can be installed in most desk top microcomputers and has been tested for the calculation of Ig concentrations in biological fluids.
