ABSTRACT
Screening for HIV infection has improved since the first immunoassays. Today, diagnosis of HIV infection can be performed with fourth-generation tests that track both the patient's antibodies and HIV antigen. The objective of this study was to evaluate the clinical sensitivity and specificity of the new DiaSorin Liaison XL Murex HIV Ab/Ag assay compared to another fourth-generation assay, the Abbott Architect HIV Ag/Ab Combo kit. This work was performed on a large panel of 900 samples, including negative samples (n = 493) and HIV-positive (n = 407) representatives of HIV-1 group M subtypes and circulating recombinant forms (CRFs), HIV-1 group O, and HIV-2 variants. The results highlight the high specificity (98.9%) and sensitivity (100%) of this new fourth-generation assay, which are consistent with its use for the screening and diagnosis of HIV infections with the current circulating strains.
