Laboratory-based survey of acquired HIV drug resistance using remnant viral load specimens

WHO’s laboratory-based acquired drug resistance survey method yields robust estimates of acquired HIV drug resistance in adults, children and adolescents taking both dolutegravir and non-dolutegravir based regimens by genotyping remnant specimens from routine viral load testing.

Results are used to inform programme decision making regarding optimal ART regimens and support evaluation of programme quality with respect to maximizing viral load suppression and minimizing emergence of resistance in people taking ART.
