## Indications for use
The ViraZyme® Influenza ID test is a direct specimen test indicated for use in the qualitative detection of both influenza types A and B virus from throat swab specimens. The ViraZyme® Influenza ID test may be used when a patient is suspected of having symptoms of an influenza-like illness. These symptoms can include, but are not limited to the following: fever of 38.5°C, sore throat, headache, myalgia, rhinitis, vomiting, chills, malaise, and cough. A positive ViraZyme® result would indicate the presence of influenza type A or B virus. A negative result is considered presumptive and should be confirmed by culture. The ViraZyme® Influenza ID test does not detect influenza C, and is indicated for in Vitro Diagnostic Use only.
