Evaluation of the Abbott LCx quantitative assay for measurement of human immunodeficiency virus RNA in plasma

J Clin Microbiol. 2002 Apr;40(4):1518-21. doi: 10.1128/jcm.40.4.1518-1521.2002.


Plasma human immunodeficiency virus RNA in 491 clinical specimens was measured by LCx. There was a strong correlation with the results provided by other methods (r(2) values of 0.93 with Cobas-Monitor version 1.5 and of 0.95 with Quantiplex version 3.0). However, values were uniformly higher with LCx than with Quantiplex when non-B subtypes were tested.
