Absence of evidence of infection with divergent primate T‐lymphotropic viruses in United States blood donors who have seroindeterminate HTLV test results

Abstract

Although the epidemiologic data suggest the possibility of undiagnosed HTLV-I, HTLV-II, or a cross-reactive virus such as PTLV among older, black, and Hispanic blood donors, the PCR data do not support the presence of divergent PTLV infection among US blood donors with HTLV-I-indeterminate results.
