RT Journal Article SR Electronic T1 Comparison of Three Commercial Kits for Determination of Triiodothyronine (T3) by Radioassay JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 38 OP 41 VO 4 IS 1 A1 Pick, Robert O. A1 Daniels, Douglas A1 Waliszewski, Jerome A. A1 Nusynowitz, Martin L. YR 1976 UL http://tech.snmjournals.org/content/4/1/38.abstract AB Three T3 radioassay kits were evaluated from the standpoint of accuracy, specificity, precision, reproducibility, sensitivity, technical performance factors, and cost. Whereas each has advantages and disadvantages in regard to each of these factors, all three kits provided acceptable results and were deemed satisfactory for use in the clinical nuclear medicine laboratory.
