Quidel QuickVue Influenza Test Offers 10-Minute Test Results to Evaluate Respiratory Symptoms

SAN DIEGO, Calif.--(BUSINESS WIRE)--April 2, 2003--Quidel Corporation (Nasdaq:QDEL), a leading provider of rapid point-of-care (POC) diagnostic tests, provides physicians the CLIA-waived, QuickVue(R) Influenza test to distinguish the symptoms of flu from those of other respiratory illnesses that mimic flu-like symptoms. The QuickVue(R) Influenza test provides fast and accurate test results at the point-of-care, to assist the physician in determining the correct diagnosis and begin appropriate treatment. Given the recent anxiety about acute respiratory illness, some patients may actually take solace in knowing they have the flu.

Access to rapid flu test results may be most important in those areas of the country where the Centers for Disease Control and Prevention (CDC) report higher prevalence of influenza this month. The CDC also indicates that personal hygiene and hand washing is the most important measure in preventing the spread of the infection.

Influenza, commonly referred to as the flu, is a serious disease and can lead to serious complications such as pneumonia and heart failure, as well as making an existing chronic disease worse. If left undetected and untreated, influenza can lead to avoidable prolonged illness and possibly even result in unnecessary death. According to the CDC, in the United States, epidemics of influenza are responsible for an average of approximately 36,000 deaths per year and 114,000 hospitalizations per year as a result of influenza.(1) Rates of infection are highest among children. Persons aged 65+ years, as well as persons of any age with chronic medical conditions, and very young children are most likely to get complications from influenza.

"Early diagnosis is critical to the proper treatment of potentially serious respiratory infections, including influenza. The sooner a physician can determine the cause of symptoms, the sooner the patient can receive targeted treatment or continue down the appropriate diagnostic path," said Michael Gerber, MD, Children's Hospital Medical Center of Cincinnati, Division of Infectious Disease. According to S. Wayne Kay, president and chief executive officer of Quidel, "The healthcare industry -- and specifically, hospitals nationwide -- are incorporating a new standard of care to test and treat patients for common but critical everyday medical conditions, such as influenza, in order to prevent potential complications, hospitalizations, and deaths from the virus."

Quidel's QuickVue Influenza test takes approximately 30 seconds of hands-on time, with results in 10 minutes or less. Depending on the type of test and sample taken (nasal swab or nasal wash), the tests are 96-99% accurate. Quidel provides additional information at www.quidel.com. By clicking on the map entitled "Flu Surveillance," information can be obtained on influenza, influenza testing and pathogens ranging from the more common to the very rare, which can cause flu-like symptoms. It provides good information in an easy to read "Frequently Asked Questions" format. The site also contains informational links to federal public health agencies like the CDC and FDA as well as a link to the AMA's "disaster preparedness" site.
