FDA Grants CLIA Waiver for Quidel Corporations QuickVue(R) RSV Test

SAN DIEGO--(BUSINESS WIRE)--Quidel Corporation (NASDAQ:QDEL - News), a leading provider of rapid point-of-care (POC) diagnostic tests, announced today that the U.S. Food and Drug Administration (FDA) granted CLIA waiver for the QuickVue® RSV test for the qualitative detection of respiratory syncytial virus (RSV). The waiver makes the QuickVue RSV test more widely available for use, especially in physician offices and clinics where waived tests are used most frequently. The QuickVue RSV test is simple and accurate, with high sensitivity and specificity.

Respiratory syncytial virus is recognized by the American Academy of Pediatrics as the leading cause of pneumonia and bronchiolitis among children two years of age and younger. RSV is a common virus with symptoms that often resemble the common cold.1 The QuickVue RSV test is intended for use as an aid in the diagnosis of acute RSV viral infections for symptomatic pediatric patients.

“We are pleased the QuickVue RSV test will now be more widely available for use by physicians, helping to aid clinical diagnosis and guide patient management decisions for some of the most fragile patients of all, infants and young children. With QuickVue tests for some of the most common respiratory ailments including influenza, Strep A, and RSV, Quidel is committed to providing physicians and caregivers with a family of rapid diagnostic tests that have a demonstrated clinical value, a prime example of how our Quidel Value Build (QVB™) strategy continues to help build our customer base,” said Caren Mason, president and CEO of Quidel Corporation.
