    Laboratory Influenza Page

    Flu banner 

    For this Influenza Season, the MDCH Bureau of Laboratories will be performing testing for all flu strains which include 2009 A H1, seasonal flu A types and Flu B. In addition, MDCH continues to highly encourage confirmatory influenza testing for cases of public health interest (ICU hospitalizations, severely ill pregnant women, patients with unusual and severe presentations, deaths) and for congregate setting outbreak/cluster investigations.  The Michigan Department of Community Health (MDCH) is reminding laboratories to please submit all rapid positive flu for confirmation.

    Please note the approved specimen types for Flu PCR analysis have been expanded to include all of the following: 

    • Upper respiratory tract specimens such as nasopharyngeal swabs (NP), nasal swabs (NS), throat swabs (TS), dual NP/TS swabs, nasal washes (NW), and nasal aspirates (NA)
    • Lower respiratory tract specimens such as bronchoalveolar lavage (BAL), bronchial washes (BW), tracheal aspirates (TA), sputum, lung tissue, and viral culture 

    For the most current updates, see the latest  MIFluFocus report   For the latest information on the current influenza season, see the MDCH Influenza Page .  


     2013-2014 Influenza Season Report  

    MDCH Laboratory Data  

    The data shown here are the results obtained by the MDCH Virology Laboratory from specimens for targeted public health testing plus surveillance testing through the Michigan Sentinel Physician and Sentinel Laboratory Programs.  The Sentinel Physician Program consists of medical provider sites from a variety of geographic locations throughout Michigan enrolled in the sentinel surveillance program. These providers represent private practice for adult and pediatric patients, as well as urgent and emergency care facilities, nursing homes and university health services. Michigan is now conducting routine influenza surveillance year round.  Thus, MDCH requests submission of two to three specimens for influenza A and B viral culture four times during the year: early influenza season, when influenza virus is beginning to circulate; middle season, during the peak of influenza activity; late season, as influenza activity diminishes; and in the summer months. Participation in this program is voluntary.  

    The influenza season runs from October through the end of September each year.

    • Laboratory Biosafety Guidelines - These biosafety guidelines have been developed for Michigan laboratories handling and processing specimens associated with influenza.  
    • To expedite receipt of laboratory results, we urge all submitters to register for fax transmittal of reports. Fax agencies receive their reports the day testing is completed. This is especially important for those submitting specimens for H5 PCR testing. Non-fax agencies receive reports via the U.S. Post Office. This method will delay your report by several days.  Registration information.
