RT Journal Article SR Electronic T1 Comparison of Certain Aspects of 24 Thyroxine I-125 Kits JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 174 OP 177 VO 7 IS 3 A1 Richard Ravel A1 Arturo Espinola YR 1979 UL http://tech.snmjournals.org/content/7/3/174.abstract 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.
