Viruses take lives. Early, accurate detection and differentiation is the first step to proper treatment.

The arrival of COVID-19 into the ecosystem changed the way we approach respiratory testing. Gone are the days of relying on a rapid test to diagnose an infection. PCR or molecular testing is now the gold standard. Its magnifying capacity allows laboratorians to detect the virus, even when there are minimal copies in the host.

Shared symptoms, different viruses

Proper treatment begins with proper diagnosis. Because influenza and COVID-19 share symptoms, accurate testing is needed to distinguish one from the other. An Emergency Use Authorized (EUA) multiplex PCR test like this one is specifically designed to detect and differentiate between multiple respiratory viruses as the ongoing COVID-19 pandemic overlaps with respiratory virus seasons. The test uses an assay design with two SARS-CoV-2 targets to compensate for emerging variants and mutations and to help provide confidence in results.

Single test to detect and differentiate between COVID-19 and influenza

The TaqPath COVID-19, Flu A, Flu B Combo Kit is a single test that can detect and differentiate between COVID-19 and influenza, which present with similar clinical symptoms, whether the sample contains one or both viruses, as in the case of a co-infection.

The TaqPath kit is a multiplex assay. This means that the user can test for more than one virus in the same run using one patient sample. This comes in handy when the COVID-19 pandemic overlaps with virus season.
