Influenza Type A and B Culture, Rapid Method (INFLUC)

LAB2127

INFLUC

Respiratory tract specimens in Quest Diagnostics supplied V-C-M medium (green-cap) tube or equivalent

1 mL

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.

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.
