  • a Includes any DBS that was prepared from plasma specimen in stratum with detectable VL, including those at lower than the lower limit of detection (LOD), which is 400 copies/ml in DBS using the CAP/CTM.

  • b All confidence intervals (CIs) are reported at the 95% confidence level.

  • c Includes any DPS that was prepared from plasma specimen in stratum with detectable VL, including those at lower than the LOD, which is 400 copies/ml in DPS using the CAP/CTM.

  • d LOD of the CAP/CTM in plasma is 20 copies/ml.
