Table 1.
Assay | Result | No. of samples in agreement with INT-O viral load assay result of: |
||
---|---|---|---|---|
Undetectable | Detected | Quantifiable | ||
LTR-O viral load | Undetectable | 88 | 4 | 10 |
Detected | 5 | 5 | ||
Quantifiable | 86 | |||
HIV RealTime | Undetectable | 76 | 2 | |
Detected | 7 | 1 | 6 | |
Quantifiable | 1 | 56 |
Quantifiable indicates a positive result (>40 copies/ml for the INT-O and HIV RealTime methods and >200 copies/ml for the LTR-O assay), and detected indicates results of between 0 and 40 copies/ml (Abbott and INT-O methods) and between 0 and 200 copies/ml (LTR-O method); these values indicate RNA detection but are not linear.
