What's this test for?

This test is ideal if you're experiencing reactions like itching, hives, swelling, stomach upset, or breathing trouble after eating hazelnuts or foods that may contain them. It's also useful if you suspect a hazelnut allergy but haven't had it confirmed, or if you want to check for sensitization before introducing hazelnuts into your diet. This test looks for a specific antibody your immune system makes when it reacts to hazelnut proteins.

What happens after I get my results?

Your results will be available in your account, with the normal range explained next to your value so you know what it means. If your result is positive, a practical next step is to avoid hazelnuts and hazelnut-containing products and watch for symptoms during accidental exposure; if it's negative but you still have symptoms, consider testing for other common allergens. You can download the standard lab report directly from your account, and if you retest in the future, the trends feature lets you track changes in your antibody level over time.

Who should consider this test?

Anyone who has had a reaction after eating hazelnuts or hazelnut-containing foods like chocolate spreads or baked goods should consider this test. It's also helpful for people with other known nut or tree pollen allergies, since cross-reactivity is common. Parents wondering whether a child's symptoms are linked to hazelnut exposure may also find this test useful.

What symptoms indicate I may need this test?

Common signs include itching or tingling in the mouth, hives or skin rash, swelling of the lips or face, stomach cramps, nausea, or vomiting after eating hazelnuts. Some people also experience nasal congestion, coughing, or wheezing. If symptoms are severe, such as difficulty breathing or swelling of the throat, seek emergency medical care right away rather than waiting on test results.

How can I naturally support my immune system around food sensitivities?

While there's no natural remedy that reverses a nut allergy, you can support your body by keeping a food and symptom diary to spot patterns, eating a varied whole-food diet, and reducing overall inflammation through good sleep and stress management. Reading ingredient labels carefully helps you avoid hidden hazelnut sources like praline, nougat, or certain oils. If you have a confirmed allergy, always carry any prescribed emergency medication with you.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification when your report is ready to view in your secure online account. No need to call or wait on hold — everything is posted digitally as soon as it's available.

What does a high result mean?

A high or positive result means your immune system has made antibodies that react to hazelnut proteins, which shows sensitization. This doesn't automatically mean you'll have a severe reaction every time, but it does mean exposure could trigger symptoms ranging from mild to serious. The higher the antibody level, the more likely a reaction is if you eat hazelnuts.

What causes a positive hazelnut IgE result?

A positive result happens when your immune system mistakenly identifies hazelnut proteins as harmful and produces antibodies against them. This can develop at any age and sometimes runs in families with other allergies, asthma, or eczema. Cross-reactivity with birch pollen or other tree nuts can also contribute to a positive result.

How often should I retest?

If you've had a positive result and are avoiding hazelnuts, retesting once a year or every couple of years can help track whether your sensitization is changing, since some allergies lessen over time. If your symptoms change or you're planning to reintroduce hazelnuts into your diet, retesting beforehand is a good idea. There's no need to retest frequently if your symptoms and avoidance plan are stable.

What should I do if my results are abnormal?

If your result is positive, avoid hazelnuts and products that may contain them, and check labels carefully since hazelnut can hide in chocolate, sauces, and baked goods. Keep track of any symptoms after accidental exposure and consider testing for related allergens like other tree nuts. If you ever experience severe symptoms like trouble breathing or swelling of the throat, treat it as an emergency and seek immediate medical care.
