Résumé
We compared three commercially available group A Streptococcus (GAS) nucleic acid amplification tests, the Quidel Solana GAS assay, the Luminex Aries Group A Strep assay and the Focus Diagnostics Simplexa Group A Strep Direct assay, with GAS bacterial culture. A true positive result was defined as one positive by culture or positive by ≥2/3 molecular methods. Two hundred eighty-seven throat swabs (207 children, 80 adults) were collected. The sensitivity of culture was 84.8% (95% CI 77.7-90.3%) with a specificity of 100% (95% CI 97.5-100%). The Solana assay sensitivity was 94.2% (95% CI 88.9-97.5%) with a specificity of 98.7% (95% CI 95.2-99.8%). Simplexa assay sensitivity was 99.3% (95% CI 96.0-99.9%) with a specificity of 95.3% (95% CI 90.6-98.1%). Aries assay sensitivity was 96.4% (95% CI 91.8-98.8%) with a specificity of 98.0% (95% CI 94.2-99.6%). In summary, all the molecular methods evaluated showed high sensitivity and specificity and were more sensitive than culture.
