Simplexa® Flu A/B & RSV Direct Kit

Simple direct detection and differentiation of influenza A virus, influenza B virus and RSV

KIT for Infectious Diseases



The CDC estimates that influenza has resulted in up to 35.6 million illnesses, 710,000 hospitalizations, and as many as 56,000 deaths annually since 2010.1

Respiratory syncytial virus (RSV) infection is more prevalent in infants and toddlers and is a leading cause of hospitalization in this age group, but RSV also causes disease in adults that can be severe in certain populations.2

2Mean values for these sites, but the three sites may not be statistically potable. Specificity at the three site ranged from 84.6% to 98.2%; Sensitivity ranged from 90.0% to 100%. See package insert for details. Sites used different culture methods for comparison, but the FDA-cleared NAAT used in the discrepancy analysis was the same at all three sites.
