What's this test for?

This test is ideal if you're experiencing fever, headache, body aches, joint pain, or a skin rash after a mosquito bite, especially during summer or fall months. It's also useful if you've had unexplained flu-like symptoms and live in or traveled to an area with reported West Nile Virus activity. The test checks for antibodies your body makes when fighting this infection, helping explain symptoms that other tests haven't.

What happens after I get my results?

Your results will appear in your online account, with each antibody level explained alongside its normal range. If your results suggest a recent or past infection, the report will explain what that means and whether retesting in a couple of weeks might help confirm the timeline of infection. You can download a standard lab report from your account at any time, and if you get tested again in the future, you'll be able to track changes over time using the trends feature. If your symptoms are severe, such as confusion, stiff neck, or muscle weakness, seek medical care right away.

What symptoms indicate I may need this test?

Common signs include sudden fever, headache, body aches, joint pain, vomiting, diarrhea, or a rash on the chest, stomach, or back. Most people with West Nile Virus have mild or no symptoms, but some develop more noticeable flu-like illness about 2 to 14 days after a mosquito bite. If you've had these symptoms along with recent outdoor exposure in mosquito season, this test can help identify the cause.

How can I naturally support recovery from a viral infection like this?

Rest, hydration, and good nutrition are the main ways your body fights off a viral infection like West Nile Virus. Drinking plenty of fluids helps your body flush out toxins while you recover, and eating foods rich in vitamin C and zinc, like citrus fruits, leafy greens, and nuts, can support your immune system. Over-the-counter pain relievers may help with fever and body aches, but always follow the label instructions. If symptoms worsen or you develop severe headache, stiff neck, or confusion, seek medical care immediately.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. You'll receive a notification as soon as your report is available in your secure online account. Because antibody levels can take time to develop after infection, timing your test appropriately (based on when symptoms started) helps ensure the most accurate results.

Who should consider this test?

Anyone who has had flu-like symptoms after a mosquito bite, especially during peak mosquito season, should consider this test. It's also a good option for people who live in or have recently traveled to areas with known West Nile Virus activity and want to understand the cause of ongoing symptoms. People who've had unexplained neurological symptoms like confusion or muscle weakness after outdoor exposure may also want to check with this test as part of figuring out next steps.

What is West Nile Virus and why does it matter?

West Nile Virus is a virus spread mainly through mosquito bites that can cause flu-like illness in some people, while most infected people have no symptoms at all. In rare cases, it can lead to more serious neurological problems, so identifying an infection matters for understanding your symptoms and recovery timeline. Testing for antibodies (IgG and IgM) helps determine whether you have a current, recent, or past infection.

What does a positive (high) antibody result mean?

A positive IgM result usually means you have a recent or current infection, since this antibody type appears early and fades over weeks to months. A positive IgG result often means you were infected at some point in the past and your body built long-term immunity. Having both positive can suggest a more recent infection that's still resolving, and retesting a few weeks later can help clarify the picture.

What does a negative (low) antibody result mean?

A negative result generally means no antibodies were detected, which usually suggests you haven't been infected with West Nile Virus, or it's too early for your body to have produced detectable antibodies. If your symptoms started very recently, within the last few days, it may be worth retesting later since antibodies take time to develop. A negative result along with ongoing symptoms is still worth monitoring closely.

How often should I retest?

If your first test is negative but you still have symptoms, retesting about 1 to 2 weeks later can help since antibody levels rise over time after infection. If your IgM is positive, a follow-up test weeks later can help confirm whether your infection is resolving as IgG levels rise and IgM levels decline. Otherwise, this isn't a test most people need to repeat regularly unless symptoms return or new mosquito exposure occurs.
