Influenza Type A and B Culture, Rapid Method (INFLUC)
Test CodeLAB2127
Quest Code
35945
Alias/See Also
INFLUC
CPT Codes
87254 (x2)
Preferred Specimen
Respiratory tract specimens in Quest Diagnostics supplied V-C-M medium (green-cap) tube or equivalent
Minimum Volume
1 mL
Instructions
To maintain optimum viability, place swab or fluid into VCM tube (equal volumes of fluid and media) or FDA approved equivalent viral transport media and transport the specimen to the laboratory as soon as possible. Best recovery is obtained when the specimens are refrigerated at 2-8° C or kept on wet ice following collection and while in transit.
If there will be a long delay before processing, specimens in transport media should be frozen at -70° C or colder and transported on dry ice. Storage or transport at -20° C is not acceptable. Raw (unpreserved) specimens should only be refrigerated and not frozen.

Clinical Significance
Influenza viruses are common human respiratory pathogens and a major cause of widespread epidemics. Infection rates usually peak during the fall, winter and spring. Rapid detection of influenza provides a basis for treating individuals with antiviral drugs and for managing outbreaks in the general population by providing vaccinations.
