The Rapid flu tests (same day-nose swab test), are best used within the first 48 hours of symptoms to help diagnose influenza and determine whether or not anti-viral medications should be used, or they are ordered within the first week to help identify outbreaks.
Currently, the rapid influenza antigen test cannot distinguish seasonal influenza from the H1N1 influenza (“swine flu”). Influenza virus grown in culture could be sent to a public health laboratory to determine if the strain of influenza A is the antigenic type (H1N1) found in pigs.
“We are encouraging the public to use good, common sense, to talk to their health-care provider about getting a flu shot, to wash their hands frequently, cover their cough, avoid touching their face and to stay home if they are sick. However, as we enter the flu season, and aware of the new H1N1 virus, we want to ensure everyone has access to an affordable rapid test for influenza,” said Dr. Isaac Farrell, director of Lab Express.
