HIV drug resistance mutation Profiles of DBS specimens collected on W-903, A-226, and M-TFN filter papers.

<p>HIV-1 drug resistance genotyping analyses of the <i>pol</i> region were performed for all the DBS specimens with a viral load ≥1,000 copies/mL and with all three types of the filter papers using a broadly sensitive genotyping assay (N = 26). Drug resistance mutations against nucleoside reverse transcriptase inhibitors (NRTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs) were identified using the HIVdb program, and HIV-1 drug resistance profiles were determined by the HIValg program at the Stanford HIV Drug Resistance Database website. Discordant mutations that were identified in only one type of filter paper are shown in boldface type. Specimens that had a difference in drug susceptibility ratings with one of the filter paper types are indicated by asterisk (*). Eight specimens with no mutations detected in any of the filter paper types were excluded from the table.</p><p>HIV drug resistance mutation Profiles of DBS specimens collected on W-903, A-226, and M-TFN filter papers.
