What does a molecular flu test detect
Molecular tests can detect influenza viral RNA (positive results) for a longer duration than other influenza testing (e.g., antigen testing-immunofluorescence or rapid influenza diagnostic tests).his guidance focuses upon molecular assays for influenza as they are increasingly being used in clinical settings (1). Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and other molecular assays can identify the presence of influenza viral RNA in respiratory specimens.
