Influenza A Detected
Influenza B Detected
Invalid
Influenza Not Detected
Influenza AH3 Detected
Influenza A 2009 H1N1pdm Detected
Influenza A(H3N2)v Presumptively Detected, specimen being forwarded to CDC for confirmation
Influenza A Virus Detected, Subtyping Not Performed
Inconclusive
Unsatisfactory (Specimen is inadequate for testing, a new specimen may need to be collected)
* Effective October 1, 2021, all specimens submitted for Influenza Real-Time PCR analysis will also receive testing for SARS-CoV-2 by Real-Time PCR analysis.
The sample collected with improper collection device—cotton-tipped or calcium-alginate swab, wooden-shaft swab, transport media not intended for viruses.
Specimen received outside of acceptable temperature requirements
Patient identifiers on specimen do not match the requisition form.
Specimen container missing patient identifiers.
Specimen quantity not sufficient for testing
Influenza typing results are typically reported the same day the specimen is received. Influenza subtyping and lineage characterization may take up to 2 business days.
