Multisite Comparison of Reproducibility and Recovery from the Standard and Ultrasensitive Roche AMPLICOR HIV-1 MONITOR Assays

Abstract
Reproducibility and recovery from the standard and ultrasensitive Roche AMPLICOR HIV-1 MONITOR kits were compared in 19 laboratories. The results were generally similar, but the consistently low level of recovery from the ultrasensitive assay in one laboratory points to the need to include external controls in order to track assay performance.
