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,1 while 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.2 On 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.3 Timely 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
Choosing speed and accuracy, anywhere and anytime is the Roche Total Solution for all that you value. The total point-of-care solution that is simply quick, gives you the confidence of PCR accuracy, and puts you in control, now with conveniently remote results, automatic reporting and one-click updates.

The cobas® liat system vs. conventional methods
Influenza A/B rapid antigen test
(Test 1 of 2)
Patient suspected of influenza
Specimen collected to perform a rapid influenza diagnostic test (RITD)
Negative result needs confirmation. Risk of delayed treatment decisions.
Samples sent to the lab for PCR testing (4-24 hours)
Patient less likely to benefit from antiviral treatment started >48 hours after symptom onset5
RSV rapid antigen test
(Test 2 of 2)
Patient suspected of RSV
Specimen collected to perform an RSV rapid antigen diagnostic test (RADT)
Negative result still leave unanswered questions. Risk of delayed treatment decisions.
cobas® Influenza A/B & RSV
(3 targets in 1 test)
Patient suspected of influenza or RSV
Specimen collected
Perform cobas® Influenza A/B & RSV test (Definitive results in 20 minutes)
Intended use
The cobas® Influenza A/B and RSV Nucleic acid test for use on the cobas® Liat® System (cobas® Influenza A/B & RSV) is an automated multiplex real-time RT-PCR assay for the rapid in vitro qualitative 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.
