| Virus detected using Xpert VL | Virus not detected using Xpert VL | Total | |
|---|---|---|---|
| Virus detected using Cobas VL | 144 (94.7%) | 8 (5.3%)a | 152 |
| Virus not detected using Cobas VL | 2 (3.3%)b | 59 (96.7%) | 61 |
a
Two had virus detected that was not in the quantifiable range (Cobas VL <1.3 log10 copies/mL or 20 copies/mL) and six had Cobas VL between 1.37 and 1.62 log10 copies/mL.
b
Both had detectable but not quantifiable Xpert VL results (i.e., <1.6 log10 copies/mL or 40 copies/mL).
