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 helps you find out quickly whether you have Influenza A or B so you can take the right next steps for treatment and to avoid spreading it to others. It's especially useful when symptoms come on suddenly during flu season.

What's included in this test?

This is a single, targeted test that checks specifically for genetic material from Influenza A and Influenza B viruses using a highly sensitive PCR method. Because it looks directly for the virus's genetic code, it can catch an infection earlier and more accurately than older methods like rapid antigen tests, which matters when you need a fast, reliable answer.

What happens after I get my results?

Your results will show up in your account, with a clear explanation of what a positive or negative result means. If you test positive, simple next steps include resting, staying hydrated, isolating from others, and watching for warning signs like trouble breathing that would call for urgent medical care. You can download a standard lab report from your account at any time, and if you get tested again later in the season, you can track your results over time using the trends feature.

How can I naturally support recovery from the flu?
Rest as much as possible so your body can focus its energy on fighting the virus. Drink plenty of fluids like water, broth, and herbal tea to stay hydrated and loosen congestion. Eating light, nutrient-rich foods and getting extra sleep can also help your immune system work more effectively, while a cool-mist humidifier may ease coughing and sore throat.
When will I get my results?
Results are typically ready within about 7 days of your sample being processed at the lab. Because PCR testing is more involved than a rapid test, it takes a bit longer, but it also tends to be more accurate. You'll be notified as soon as your results are available in your account.
Who should consider this test?
Anyone with sudden flu-like symptoms, especially during flu season, is a good candidate for this test. It's also useful for people who live or work around others at higher risk, like older adults or those with weakened immune systems, since knowing your status helps prevent spreading the virus. People who want a more accurate answer than a rapid antigen test can provide should also consider this option.
What symptoms indicate I may need this test?
Common signs include sudden fever, chills, dry cough, sore throat, runny or stuffy nose, muscle or body aches, headaches, and fatigue. Some people also experience vomiting or diarrhea, though this is more common in children. If these symptoms appear suddenly and feel more intense than a typical cold, it may be worth checking for influenza.
What is influenza and why does it matter?
Influenza is a contagious respiratory virus that spreads easily from person to person, especially in fall and winter months. It matters because it can range from mild to severe, and in some people it can lead to serious complications like pneumonia. Knowing whether you have Influenza A or B helps you manage your symptoms appropriately and take steps to protect the people around you.
What causes a positive or negative result to change over a flu season?
A positive result means the virus's genetic material was found in your sample, meaning you're currently infected. A negative result means no viral genetic material was detected at the time of testing, but if your symptoms started very recently, there's a small chance the virus level was too low to detect yet. Retesting a couple of days later can help clarify unclear situations if symptoms persist or worsen.
What should I do if my results are positive?
If you test positive, focus on resting, staying hydrated, and isolating yourself from others to prevent spreading the virus. Over-the-counter medications can help manage fever and aches, but if you experience difficulty breathing, chest pain, confusion, or symptoms that suddenly worsen, seek medical care right away. Most healthy people recover within one to two weeks with rest and supportive care at home.

What this means

A negative result means no genetic material from Influenza A or B was found in your sample, so you likely do not have an active flu infection. If your symptoms are severe or just started, a repeat test may be worth considering since very early infections can sometimes be missed.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
