Regular ArticlesEvaluation of the Abbott Investigational Use Only RealTime HIV-1 Assay and Comparison to the Roche Amplicor HIV-1 Monitor Test, Version 1.5
چکیده انگلیسی

Abbott Molecular's m2000 system and RealTime HIV-1 assay (RealTime) were evaluated for sensitivity, reproducibility, linearity, ability to detect diverse HIV-1 subtypes/groups, and correlation to the Roche AMPLICOR HIV-1 MONITOR Test, Version 1.5 (Amplicor). The limit of detection was determined using the second International World Health Organization Standard and Viral Quality Assurance standard material. Serial dilutions of four patient samples were used to determine inter- and intra-assay reproducibility and linearity. Samples representing HIV-1 groups M, N, and O were evaluated in the RealTime, Amplicor, and Siemens Versant HIV-1 branched chain DNA 3.0 (Versant) assays. Archived Amplicor-tested samples were tested with the 1 ml, 0.5 ml, and 0.6 ml versions of the RealTime assay. Probit analysis predicts a limit of detection of 21.94 IU/ml using the World Health Organization Standard and 26.54 copies/ml using Viral Quality Assurance material with the 1 ml assay. Linearity and reproducibility were very good between ∼1.60 to 6.0 log10 copies/ml. All three assays produced similar measurements for all Group M subtypes tested; the RealTime assay was the only assay that detected all three Group O samples tested. Correlation with the Amplicor assay was good, although the RealTime assay measured between 0.342 and 0.716 log10 copies/ml lower on average, depending on the input volume. The automated RealTime assay exhibits excellent sensitivity, dynamic range, reproducibility, and group/subtype detection, albeit with consistently lower values than Amplicor.
