What's this test for?

This test is ideal if you're experiencing flu-like symptoms such as fever, chills, cough, sore throat, body aches, or fatigue and want to know if influenza is the cause. It can also help if you've been around someone who was diagnosed with the flu and want to confirm whether you've caught it. Knowing whether you have Influenza A or B can help you understand how long symptoms may last and how to manage them.

What happens after I get my results?

Your results will show up in your account as either positive or negative for Influenza A or B, with a plain-language explanation of what that means. If positive, next steps usually include resting, staying hydrated, and isolating from others until your fever is gone for at least 24 hours; if your symptoms are severe or you have trouble breathing, seek medical care right away. You can download a standard lab report from your account at any time, and if you get tested again during a future illness, you can track those results over time using the trends feature.

Who should consider this test?

Anyone with sudden flu-like symptoms — fever, cough, sore throat, muscle aches, fatigue — is a good candidate for this test. It's especially useful for people who are around young children, older adults, or anyone with a weaker immune system, since knowing the exact virus helps you take the right precautions to avoid spreading it. It's also helpful if you want to rule out other illnesses with similar symptoms, like a common cold or COVID-19.

What symptoms indicate I may need this test?
Common signs that point to needing this test include a sudden high fever, chills, dry cough, sore throat, runny or stuffy nose, muscle or body aches, headaches, and unusual tiredness. These symptoms often come on quickly, unlike a regular cold which tends to build up slowly. If you notice several of these symptoms together, especially during flu season, this test can confirm whether influenza is the cause.
When will I get my results?
Results for this test are typically ready within about 7 days from when your sample is received at the lab. You'll get a notification and can log into your account to view your results as soon as they're available. Because flu symptoms move fast, some people find it helpful to start supportive care right away while waiting on confirmation.
How can I naturally support recovery from the flu?
While there's no substitute for rest, there are simple things that can help your body fight off the flu virus. Drink plenty of fluids like water, herbal tea, and broth to stay hydrated, and get extra sleep so your immune system can focus on recovery. Eating light, nutritious foods and using a humidifier can also ease congestion and sore throat discomfort.
What is influenza and why does it matter?
Influenza, or the flu, is a contagious virus that infects your nose, throat, and lungs, causing symptoms like fever, cough, and body aches. It matters because it can range from mild to severe, and in some people — especially young children, older adults, or those with weaker immune systems — it can lead to serious complications like pneumonia. Knowing whether you have Influenza A or B also helps you understand how contagious you might be and how to protect people around you.
What does a positive result mean?
A positive result means the test found genetic material from the influenza virus in your sample, confirming you currently have the flu. This means you should rest, isolate from others as much as possible, and manage symptoms with fluids and over-the-counter remedies as needed. If your fever is very high, doesn't improve, or you develop trouble breathing or chest pain, seek medical care right away.
What causes a positive or negative result?
A positive result happens when you're actively infected with Influenza A or B and the virus is present in your nose or throat at the time of testing. A negative result usually means you don't currently have the flu, though testing very early or very late in an illness can sometimes affect accuracy. If your symptoms continue despite a negative result, retesting or checking for other illnesses may be worthwhile.
How often should I retest?
You generally don't need to retest unless new flu-like symptoms appear again, since a single infection typically doesn't need repeat confirmation once it runs its course. If you develop new symptoms weeks or months later, that may represent a new infection worth testing again. Retesting is also reasonable if your symptoms don't improve within the expected timeframe and you want to rule out a different illness.
