[The indirect solid-phase method of immunoenzyme analysis, its accuracy and sources of error].

The study of the accuracy of the enzyme-linked immunosorbent assay has revealed that the accuracy of this assay is low. The influence of instruments (dispensers, photometers, plates) on the accuracy of the assay has been studied. As shown in this study, the main sources are titration procedures and differences in the adsorption and optical properties of available plates, those manufactured in the USSR giving greater errors.
