We offer influenza testing for $40. The results are available in 10 minutes, and if you test positive we can prescribe the antiviral Tamiflu (oseltamivir) for you. This medication reduces symptom severity and duration of influenza. Flu tests are available at our Larsen-Mayer (3825 39th Ave) and Racine (5220 Washington Ave) locations. Flu testing and treatment is for adults only.
