DBS collected from 80 treatment-naive HIV-infected patients presenting in three hospitals of two different regions of Thailand were shipped to a central laboratory along with corresponding plasma specimens. Viral load was measured in both DBS and plasma using the Abbott m2000 system. HIV RNA levels were strongly correlated (r = 0.94) with a mean of differences of 0.23 log(10) copies/mL. Using the 1,000 copies/mL cut-off, the sensitivity of DBS was 97% (95%CI, 91-100%) and specificity was 75% (95%CI, 19-99%). DBS are useful to scale-up HIV RNA VL testing in settings with limited access to VL testing. 052 ; 020 Thaïlande
