Abstract
This study compared the Altona RealStar™ VZV Kit 1.0 real time quantitative VZV PCR with in-house qualitative conventional VZV PCR on cerebrospinal fluid, mucocutaneous, and other uncommon clinical specimens. Overall, positive and negative agreement percentages were respectively 97.9% (95%CI: 93.8-99.6), 100.0% (95%CI: 93.1-100.0), and 96.3% (95%CI: 89.4-99.2) while Cohen's kappa statistic value was 0.96 (95%CI: 0.91-1.00). RealStar™ VZV quantitative PCR assay reported average quantitative viral loads of 4.4 × 105 and 1.1 × 107 copies/mL in cerebrospinal fluid and cutaneous specimens, respectively (P < 0.01). RealStar™ VZV PCR assay showed excellent agreement with in house conventional assay for various clinical specimens.
