What's this test for?

This test is ideal if you're experiencing sudden fever, chills, headache, muscle aches, or a dry cough during flu season. It helps determine whether you have influenza and, if so, which type — A or B — you're dealing with. Knowing this quickly can help you decide on the right next steps for treatment and for protecting people around you.

What happens after I get my results?

Your results will show up in your account as Positive or Negative for both influenza A and B, with a plain-language explanation of what each result means. If you test positive, next steps typically include resting, staying hydrated, and monitoring your symptoms, while seeking urgent medical care if you develop trouble breathing, chest pain, or a high fever that won't come down. You can download a standard lab report from your account at any time, and if you get tested again this season, you can track results over time using the trends feature.

What symptoms indicate I may need this test?

Sudden onset of fever, chills, body aches, headache, fatigue, and a dry cough are the classic signs that point to influenza. Sore throat and congestion can also show up, especially if symptoms hit hard and fast rather than building up slowly like a common cold. If these symptoms appear during flu season, this test can help confirm the cause.

When will I get my results?
Results are typically available within about 7 days of your sample being processed at the lab. Because influenza symptoms move fast, it's a good idea to check your account regularly during this window so you can act on your results as soon as they're ready.
Who should consider this test?
Anyone with sudden flu-like symptoms during cold and flu season is a good candidate for this test, especially people who are around vulnerable individuals like young kids, older adults, or those with weakened immune systems. It's also useful for people who want to confirm whether their illness is influenza versus another respiratory infection so they can respond appropriately.
How can I naturally support recovery from the flu?
Rest as much as possible, drink plenty of fluids like water and warm broths, and eat light, nutritious foods to support your immune system. A humidifier or warm shower can ease congestion and cough, and honey (for adults and older kids) can help soothe a sore throat. Avoid pushing through activity — your body needs energy to fight the virus.
What is influenza and why does it matter?
Influenza is a contagious virus that causes sudden fever, body aches, and respiratory symptoms, and it tends to spread widely during colder months. It matters because flu can range from mild to severe, and knowing whether you have influenza A or B helps guide the right care and helps you avoid spreading it to others. Distinguishing the type also matters because certain treatments work better against specific strains.
What does a positive result mean?
A positive result means the test detected influenza A or B virus in your sample, confirming you currently have the flu. This means you should rest, isolate from others when possible, and monitor your symptoms closely for any signs of worsening, such as difficulty breathing or a persistent high fever, in which case you should seek medical care right away.
What should I do if my results are abnormal?
If you test positive for influenza A or B, focus on rest, hydration, and symptom management like fever reducers as needed. Limit contact with others to avoid spreading the virus, especially around young children, older adults, or anyone with a weakened immune system. If symptoms worsen or you develop trouble breathing, chest pain, or confusion, seek medical care immediately.
How often should I retest?
You generally don't need to retest for the same flu illness once you've confirmed a diagnosis, but if new flu-like symptoms appear later in the season, a fresh test can help identify whether it's a new infection. Testing again is especially useful if symptoms return after you thought you'd recovered.

A negative result means no influenza A or B antigen was detected in your sample, suggesting your symptoms are likely due to another cause, such as a cold virus. If symptoms are severe or persist, another illness may be responsible and further evaluation may be needed.
