HIV RNA measurement in dried blood spots of HIV-infected patients in Thailand using Abbott m2000 system Khamduang, W. Kaewbundit, A. Duangmano, A. Hongjaisee, S. Klinbuayaem, V. Halue, G. Chutanunta, A. Sirirungsi, W. /Jourdain, Gonzague /Ngo-Giang-Huong, Nicole World Health Organization recommends using dried blood spots (DBS) for HIV RNA viral load (VL) measurement whenever plasma processing is not convenient or feasible. 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. 2020 text https://www.documentation.ird.fr/hor/fdi:010078131 fdi:010078131 Khamduang W., Kaewbundit A., Duangmano A., Hongjaisee S., Klinbuayaem V., Halue G., Chutanunta A., Sirirungsi W., Jourdain Gonzague, Ngo-Giang-Huong Nicole.
