title: [Effect of the conditions of isolation of free and bound ligands on the accuracy of the radioimmunoassay of steroids].
abstract: Testosterone radioimmunoassay (RIA) was used to analyse the factors which influenced the precision and accuracy of steroid RIA. Selection of optimal parameters (concentrations of activated charcoal and of the radioactive steroid) was necessary in order to reduce the influence of non-specific binding and error of fractionation on the RIA results. The scheme for estimation of the optimal values of these parameters is described.
