Fig. 1From: HIV-1 drug resistance genotyping success rates and correlates of Dried-blood spots and plasma specimen genotyping failure in a resource-limited settingTrends in the median VLs of the specimen genotyped over the years. Median VLs were determined for all specimens analysed in each year. Overall median VLs for DBS and plasma, and General median VLs represent values obtained for specimens over the 4Â yearsBack to article page
