Applicability of flow cytometry in detecting patients with active ATL. The assay was performed using sera (diluted at 1/256) from patients BT, 1, 2 and 5 years PT. The results were expressed as percentage of positive fluorescent parasites (PPFP). The dotted line represents the cut-off point between negative and positive results (cut-off = 20%) (a). IgG reactivity in sera from patients BT, 1, 2 and 5 years PT submitted to the ELISA test. The dotted line represents the cut-off point between negative and positive results (cut-off = 1:40) (b). Comparison between the ROC curves of ELISA and Flow Cytometry (c)
