Overview
Other Diagnostic Studies
Molecular Assays Adapted from CDC [1]
- Tests for influenza include molecular assays, rapid influenza diagnostic tests, viral culture or serology.
- Molecular assays for influenza are increasingly being used in clinical settings.
- Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and other molecular assays can identify the presence of influenza viral RNA in respiratory specimens.
- RT-PCR is particularly useful to identify influenza virus infection as a cause of respiratory outbreaks in institutions, such as nursing homes, chronic care facilities, and hospitals.
- Some molecular assays are able to detect and discriminate between infections with influenza A and B viruses; other tests can identify specific influenza A virus subtypes [A(H1N1)pdm09, seasonal A (H1N1), or seasonal A (H3N2)].
- These assays can yield results in 3-8 hours.
- Notably, the detection of influenza viral RNA by these assays does not always indicate detection of viable virus or on-going influenza viral replication.
- It is important to note that not all assays have been cleared by the FDA for diagnostic use.
