COVID-19, Flu, and RSV test

There's more than just the flu to worry about this fall. If you're not feeling well, it could be SARS-CoV-2 (COVID-19), flu, or a sinus infection (respiratory syncytial virus or RSV). Symptoms of these respiratory infections are often similar, making it difficult to determine what might be making you feel sick.

With just 1 combination swab, the COVID-19, Flu, and RSV test helps you and your doctor determine if you have COVID-19, the flu, or RSV. It eliminates the need for multiple tests or doctor visits, and can help you get the right treatment plan as soon as possible. The combination testing approach helps increase testing capacity during the busy flu season and speeds up the time to a diagnosis.

Is it COVID-19, flu, or RSV?

Whether caused by COVID-19, influenza, or RSV, the symptoms can be very similara:

  • Fever or feeling feverish/chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Fatigue (tiredness)
  • Sore throat
  • Runny or stuffy nose
  • Muscle pain or body aches
  • Headache
  • Vomiting and diarrhea (more common in children than adults)

If you have symptoms

If you have symptoms that could be from the flu, RSV, or COVID-19, you should quarantine as a precaution. Call your healthcare provider and discuss your symptoms before any visit for testing.

Knowing if you have COVID-19 means you can take steps to avoid spreading the disease and alert those who you were in contact with who may have been exposed. If diagnosed early, there may be more treatment options available to you.

Regardless of your test result, you should continue to follow recommendations from the Centers for Disease Control and Prevention (CDC) and local guidelines regarding COVID-19 safety practices.
