cobas® SARS-CoV-2 &
Influenza A/B Assay

Rapid answers to manage the unknown

Reduce the risk of a misdiagnosis with an accurate test you can trust

Symptoms of COVID-19 and influenza may look the same. It can be difficult for clinicians to identify based on signs & symptoms alone and if left undiagnosed, may result in health complications or community spread.

The cobas® SARS-CoV-2 & Influenza A/B test for use on the cobas® Liat® System provides urgent, accurate answers to rule-in or rule-out influenza and COVID-19 in 20 minutes from a single test, enabling early and effective early patient care.

cobas® SARS-CoV-2 & Influenza A/B:

  • One sample, one test, 20 minutes, know if it’s COVID-19 or Flu
  • Take the workload out of testing with simple intuitive user handling
  • Minimize cross-contamination and risk of exposure during testing with the closed-system design

With the unique combination of a targeted menu of molecular POC assays, the cobas® Liat® System, and the cobas® infinity POC solution, Roche offers the total point-of-care PCR solution, empowering healthcare professionals to help their patients more efficiently.

Intended Use

Intended Use

The cobas® SARS-CoV-2 & Influenza A/B Nucleic acid test for use on the cobas® Liat® System (cobas® SARS-CoV-2 & Influenza A/B) is an automated multiplex real-time RT-PCR assay intended for the simultaneous rapid in vitro qualitative detection and differentiation of SARS-CoV-2, influenza A, and influenza B virus RNA in healthcare worker-collected nasopharyngeal and nasal swabs and self-collected nasal swabs (collected on site with instruction by a healthcare professional) from individuals suspected of respiratory viral infection consistent with COVID-19 by their healthcare provider. Clinical signs and symptoms of respiratory viral infection due to SARS-CoV-2 and influenza can be similar.

 

cobas® SARS-CoV-2 & Influenza A/B is intended for use in the detection and differentiation of SARS-CoV-2, influenza A, and influenza B in clinical specimens and is not intended to detect influenza C. SARS-CoV-2, influenza A and influenza B viral RNA is generally detectable in upper respiratory specimens during infection. Positive results are indicative of active infection but do not rule out bacterial infection or co-infection with other pathogens not detected by the test. Clinical correlation with patient history and other diagnostic information is necessary to determine patient infection status. The agent detected may not be the definite cause of disease. 

Negative results do not preclude infection from SARS-CoV-2, influenza A, and/or influenza B and should not be used as the sole basis for diagnosis, treatment or other patient management decisions. Negative results must be combined with clinical observations, patient history, and/or epidemiological information.

 

Negative results obtained from individuals who are not exhibiting clinical signs and symptoms associated with respiratory viral infection at the time of specimen collection should be interpreted with particular caution. Negative results in asymptomatic individuals cannot be used as definitive evidence that an individual has not been exposed to SARS-CoV-2 or influenza viruses and has not been infected with any of these viruses. 

 

cobas® SARS-CoV-2 & Influenza A/B is intended for use by health professionals or trained operators who are proficient in using the cobas® Liat® System at the point of care (POC) or in a clinical laboratory setting.

In the United States (US), testing with cobas® SARS-CoV-2 & Influenza A/B is authorized for laboratories certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA), 42 U.S.C. §263a, to perform moderate or high complexity tests. cobas® SARS-CoV-2 & Influenza A/B is also authorized for use at the Point of Care (POC), i.e., in patient care settings operating under a CLIA Certificate of Waiver, Certificate of Compliance, or Certificate of Accreditation. Testing facilities within the U.S. and its territories are required to report all SARS-CoV-2 results to the appropriate public health authorities. In the U.S., cobas® SARS-CoV-2 & Influenza A/B is only for use under the Food and Drug Administration’s Emergency Use Authorization.

In the United States:

 

• This test has not been FDA cleared or approved;

• This test has been authorized by FDA under an EUA for use by authorized laboratories;

• This test has been authorized only for the simultaneous qualitative detection and differentiation of nucleic acid from SARS-CoV-2, influenza A virus and influenza B virus; not for any other viruses or pathogens; and

• This test is only authorized for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of in vitro diagnostic tests for detection and/or diagnosis of COVID-19 under section 564(b)(1) of the Act, 21 U.S.C. § 360bbb- 3(b)(1), unless the authorization is terminated or revoked sooner
