  1. Eight cases (A-I) represent a subset of complex case studies for which the initial classifications, based on the Two of Three rule, and final resolutions differed. Final
  2. resolutions were based on repeat rapid test results and/or HIV-RNA detection (HIV-RNA viral load). Clearly positive result (+); clearly negative result (-); indeterminate result (D); absent result (A).
