These combination tests work by testing a single sample from a patient for multiple respiratory diseases, such as COVID-19 and the seasonal flu which can show similar symptoms

The US Food and Drug Administration further assisted healthcare providers to prepare for the upcoming flu season during the COVID-19 pandemic by issuing an emergency use authorisation (EUA) for the third diagnostic test for detection and differentiation of the viruses that cause flu and COVID-19 in individuals suspected of COVID-19 by their healthcare provider. The FDA has previously issued EUAs to BioFire Diagnostics LLC and QIAGEN GmbH for their tests in the US, which include many other respiratory organisms in addition to the viruses that cause flu and COVID-19.

With the authorisation of these tests, the FDA is helping address concerns in anticipation of this upcoming flu season during the COVID-19 pandemic, which might be especially worrying for some Americans. This is another example of the FDA working with test developers to bring important diagnostics to Americans,” said FDA Commissioner Stephen M Hahn, MD “With just one swab or sample, combination tests can be used to get answers to Americans faster. This efficiency can go a long way to providing timely information for those sick with an unknown respiratory ailment.”

These combination tests work by testing a single sample from a patient for multiple respiratory diseases, such as COVID-19 and the seasonal flu which can show similar symptoms. There are several important advantages to this combination testing. Taking just one sample from a patient may help alleviate the need for multiple samplings, which means less discomfort for the patient with faster and more comprehensive results. In addition, combination tests require fewer supplies, such as swabs and personal protective equipment, and reduce pressure on the supply chain for reagents.

The FDA encourages additional developers to work with the FDA on combination tests that may be useful in preserving critical testing resources in the upcoming flu season during the COVID-19 pandemic. The FDA has updated the Molecular Diagnostic EUA templates to add information about these types of tests to help facilitate the preparation, submission, and authorisation of EUAs of combination tests that address the COVID-19 public health emergency.
