Accuracy testing of HTLV-1 diagnostic serological assay kits available in Japan on samples verified as positive or negative for HTLV-1. To evaluate the performances of the HTLV-1 diagnostic assay kits commercially available in Japan for HTLV-1 antibodies, 50 samples definitively positive for HTLV-1 antibodies and 50 samples definitively negative for HTLV-1 antibodies were tested with the 10 assay kits (kit A: PA, BF: CLEIA, G: CLIA, H: ECLIA, I: WB, and J: LIA) listed in Table 1, according to the manufacturers' instructions. The number of HTLV-1-reactive, -positive, -negative or -indeterminate results determined by each kit is shown. Based on these results, the performance accuracy of each kit used was assessed. R: reactive, P: positive, N: negative, and I: indeterminate
