Influenza Testing Update: April 2022

West Michigan influenza infections peaked mid-March 2022 and have been declining in the weeks that followed. Now with a low prevalence of circulating influenza, using the most sensitive diagnostic test is recommended in order to obtain accurate and actionable results. Influenza antigen testing (e.g. Sofia instrument) is no longer appropriate at this time and Influenza PCR testing should be ordered when clinically indicated.
