MICHIGAN INNOVATIVE DIAGNOSTICS

Molecular assay that detects and differentiates SARS-CoV-2, influenza A, influenza B, and RSV from a single respiratory specimen using our laboratory-developed real-time RT-PCR method, used to identify the cause of acute respiratory illness when symptoms overlap.

​

LIS PANEL CODE: (MID) Respiratory Multiplex PCR (4PLEX) Panel

​

INDIVIDUAL LIS TEST CODES INCLUDED WITHIN PANEL: SARS-CoV-2, Influenza A, Influenza B, RSV
