Detects and differentiates influenza A, influenza B and RSV

The young and old are particularly vulnerable to respiratory infections. Influenza has been known to kill up to 650,000 people every year,1while RSV is the leading cause of lower respiratory disease in children younger than 4 years of age; globally, nearly all children have been infected with RSV at least once, by age two.2On the other end of the age continuum, RSV is also common in adults older than 65 and their risk of serious infection increases with age.3Timely test results can help guide clinical decisions regarding treatment and patient isolation for infection control.

cobas®Influenza A/B & RSV delivers:

  • Three viruses, 20 minutes to diagnosis, for your patients at higher risk
  • Simple to use with minimal hands-on-time, and easy interpretation of results
  • When it is not COVID-19, and other respiratory viruses are suspected


The growing menu of molecular POC assays together with this innovative, connected analyzer, forms the Roche total point-of-care PCR solution. Now, emergency rooms, primary care and other novel POC settings can reliably standardize and mobilize molecular testing, enhancing patient safety and satisfaction.

Thecobas®Influenza A/B and RSV Nucleic acid test for use on thecobas®Liat®System (cobas®Influenza A/B & RSV) is an automated multiplex real-time RT-PCR assay for the rapidin vitroqualitative detection and discrimination of Influenza A virus, Influenza B virus and respiratory syncytial virus (RSV) RNA in nasopharyngeal swab specimens from patients with signs and symptoms of respiratory infection in conjunction with clinical and epidemiological risk factors. The test is intended for use as an aid in the differential diagnosis of Influenza A, Influenza B, and RSV in humans and is not intended to detect Influenza C.

CE-IVD, FDA 510(k) cleared, CLIA waived

Thecobas®Liat®System is commercially available in select markets. This product is not registered as anin vitro诊断(试管)countries; additional information may be available from your Roche sales representative.
