As part of a research project (ethics approval 469/2013), she had a drug resistance test (DRT) with a validated in-house Sanger-based sequencing method before the initiation of ART, which showed no HIVDR mutations, and again after 12 months, which revealed six nucleoside/nucleotide reverse transcriptase inhibitor (NRTI) and three non-nucleoside reverse transcriptase inhibitor (NNRTI) mutations (Tables 1 and 2). A search of the NHLS database for evidence of prior HIV-related testing revealed two VL results (2012 and 2013), which precede her ART-initiation date (Figure 1).
