Detection of Herpes Simplex Virus and Varicella-Zoster Virus by Traditional and Multiplex Molecular Methods.
AMERICAN JOURNAL OF CLINICAL PATHOLOGY(2019)
摘要
Objectives To compare multiplex nucleic acid amplification tests (NAATs) that detect and differentiate herpes simplex virus (HSV) and varicella-zoster virus (VZV) with traditional virologic assays. Methods The HSV ELVIS Test System (Quidel, San Diego, CA) and/or Light Diagnostics VZV direct fluorescent antibody (DFA) kit (Millipore Sigma, Billerica, MA), as well as an ARIES HSV 1&2/VZV assay (Luminex, Austin, TX) and the Solana HSV1 + 2/VZV Assay (Quidel), were performed on non-cerebrospinal fluid specimens. Results The sensitivities/specificities for the ELVIS, Aries, and Solana assays for HSV were 71.1%/93.2%, 94.9%/93.2%, and 94.7%/100%, respectively. The sensitivities/specificities for the DFA, Aries, and Solana assays for VZV were 71.4%/100%, 100%/96.0%, and 95.3%/100%, respectively. HSV and VZV were detected but clinically unsuspected in 5.4% and 4.2% of the specimens, respectively. Conclusions Both NAAT assays were comparable and more sensitive than traditional methods. The recovery of unsuspected HSV and VZV from clinical specimens supports the implementation of a combined HSV/VZV assay.
