Overview
Diagnostic tests available for influenza include viral culture, serology, rapid antigen testing, polymerase chain reaction (PCR), immunofluorescence assays, and other molecular assays. Sensitivity and specificity of any test for influenza might vary by the laboratory that performs the test, the type of test used, and the type of specimen tested. Among respiratory specimens for viral isolation or rapid detection, nasopharyngeal specimens are typically more effective than throat swab specimens. As with any diagnostic test, results should be evaluated in the context of other clinical and epidemiologic information available to healthcare providers.
Laboratory Findings
Leukocyte counts may be normal or low, with lymphopenia or thrombocytopenia in some cases. In severe disease, other laboratory abnormalities indicative of complications may be present.[1][2]
