^aSpecimens were air dried and stored at ambient temperature for 4 to 7 days prior to testing. TruGene HIV-1 genotyping kit-derived real-time first-pass sequences were used as the “gold standard” reference sequence for comparison to dried ST specimens. Stringency of scoring includes IUB base codes for mixture detection.
