Quidel Corporation (NASDAQ: QDEL), a provider of rapid diagnostic testing solutions, cellular-based virology assays and molecular diagnostic systems, announced today it has received 510(k) clearance and Clinical Laboratory Improvements Amendments (CLIA) waiver from the United States Food and Drug Administration (FDA) for Quidel’s Sofia RSV Fluorescent Immunoassay (FIA) to be used with the Sofia 2 Fluorescent Immunoassay Analyzer for the rapid detection of respiratory syncytial virus (RSV) infections in nasopharyngeal swab and nasopharyngeal aspirate/wash specimens taken directly from symptomatic pediatric patients.

Sofia 2 is Quidel’s next-generation version of its best-selling Sofia instrumented system. Sofia 2 utilizes the original Sofia’s fluorescent chemistry design while improving upon the graphical user interface and optics system to provide an accurate, automated and objective result in as few as 3 minutes. Sofia 2 also integrates wireless connectivity and its barcode scanner within a smaller footprint than the legacy Sofia instrument.

The next-generation Sofia system also comes connected to Virena®, Quidel’s data management system, which provides aggregated, de-identified testing data in near real-time.

The Sofia RSV assay employs advanced lateral flow and immunofluorescence technologies to provide enhanced clinical sensitivity for RSV, one of the most serious respiratory diseases in children and seniors. These technologies help ensure a reliable, objective, rapid, and accurate diagnostic result. The Centers for Disease Control and Prevention (CDC) estimate that Respiratory Syncytial Virus, or RSV, leads to 2.1 million annual outpatient visits among children younger than 5 years old, and that 25% - 40% of young children infected with RSV for the first time will exhibit signs of pneumonia or bronchiolitis.1,2

In addition to the several thousand hospitals, medical centers and smaller clinics in the United States, the receipt of CLIA waiver markedly expands the available market for the Sofia 2 test system.

“With the clearance of Sofia Influenza A+B and Sofia RSV on the new Sofia 2 instrument, we are now able to diagnose two of the most common respiratory diseases more quickly, more easily and at a lower cost; a perfect fit for the specific needs of the point-of-care space,” said Douglas Bryant, president and chief executive officer of Quidel Corporation. “We see Sofia 2 building on the success of our original Sofia flagship product by expanding our instrument placements into the smaller, lower volume physician offices as well as the higher volume health systems, while also significantly growing our Virena wireless coverage throughout the country.”

Sofia 2 received CLIA waiver for the Sofia Influenza A+B assay from the FDA in May, and is now available for sale in the U.S.
