Nucl. Med. Technol.1979 Sep 01; 7 AB - We compiled data comparing certain aspects of 24 T4 kits: 18 RIA and 6 CPB. We found significant differences in reproducibility among kits, as well as variance in number of pipetting steps, incubation time, reagent preparation, and cost. This information may assist in selecting kits for user evaluation. Technologists may not depend solely on assurances by manufacturers’ representatives when choosing a kit.
