Table 2.
Samples with discordant results on confirmatory assays are depicted in a box.
ID, identification number of the sample; Ct, cycle threshold value; Ct1, cycle threshold (pol) HTLV-1; Ct2, cycle threshold (pol) HTLV-2; Ct3, cycle threshold of albumin (control); NEG, negative; IND, indeterminate; ND, not done; HTLV, human T lymphotropic virus; HTLV-1, human T lymphotropic virus type 1; HTLV-2, human T lymphotropic virus type 2.
a Results according to criteria described in Materials and Methods.
