What's this test for?

This test is ideal if you're experiencing reactions after eating walnuts or foods that may contain walnut, such as hives, itching, swelling, stomach upset, or breathing trouble. It's also useful if a whole-food walnut allergy screen came back positive but you want to know how likely a true allergy actually is. This helps you understand your risk more precisely instead of just guessing based on a broad screen.

What's included in this test?

This test measures specific walnut protein components rather than just whole walnut extract, which helps show whether your immune system is reacting to proteins linked to severe reactions or to ones more often tied to mild, cross-reactive symptoms. Breaking the allergy down by component gives a clearer picture of real-world risk than a single whole-food result can.

What happens after I get my results?

Your results will show up in your account with each value's normal range explained in plain language, so you can see exactly where you stand. If a component comes back elevated, practical next steps include avoiding walnuts and cross-reactive foods, carrying appropriate emergency medication if you've reacted before, and retesting if your symptoms change over time. You can download a standard lab report straight from your account whenever you need it. The trends feature also lets you track this result alongside future tests to see how things change.

How can I naturally support a healthy immune response to food allergens?

While you can't train your immune system to stop reacting to a true allergen, you can support your body by eating a varied, anti-inflammatory diet rich in fruits, vegetables, and omega-3 fats. Managing gut health with fiber and fermented foods may also help support overall immune balance. Avoiding known trigger foods remains the most reliable way to prevent reactions while your body's response is being evaluated.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. You'll get a notification once they're posted to your account, so there's no need to call or check in manually.

Who should consider this test?

This test is a good fit for anyone with a history of reactions after eating walnuts or foods that may contain walnut traces. It's also worth considering if you've had a positive whole-food walnut allergy screen and want more detail before making major dietary changes. People managing tree nut allergies in general may also find it useful for narrowing down which specific nuts pose real risk.

What symptoms indicate I may need this test?

Common signs include hives, itchy skin, swelling of the lips or face, stomach cramps, nausea, or trouble breathing after eating walnuts or walnut-containing foods. Milder symptoms like an itchy mouth or throat right after eating can also point to a reaction worth investigating. If you've ever had a severe reaction like difficulty breathing or swelling of the throat, seek medical care right away rather than waiting on test results.

What does a high result mean?

A high result on a walnut component means your immune system has produced antibodies against specific walnut proteins, which raises the likelihood that a real allergy is present. Certain components are more strongly linked to severe reactions, while others are more often associated with milder, cross-reactive symptoms. Either way, a high result is a signal to avoid walnuts and discuss an action plan with an allergy specialist if you haven't already.

What causes a high walnut component result?

A high result happens when your immune system mistakenly identifies walnut proteins as harmful and creates antibodies against them, a process that can develop at any age. Genetics, early food exposure, and having other allergies (like other tree nuts or pollen) can all increase the chance of this happening. Repeated exposure to walnut proteins, even in small amounts, can also reinforce the immune response over time.

How often should I retest?

If you're currently avoiding walnuts and managing symptoms well, retesting once a year or if your symptoms change is generally reasonable. If you've recently changed your diet or want to confirm whether a childhood allergy has changed over time, retesting sooner can provide useful updated information. Always retest before intentionally reintroducing walnut into your diet.
