Allergy Test - Nuts

About this test

Key Benefits

• Identify potential allergy to peanuts and hazelnuts.

• Simple At-Home Testing: Collect your sample using a finger-prick blood test.

• Targeted Food Insight: Focus on two of the most common food allergens.

• Cross-Reactivity Awareness: Understand potential reactions linked to pollen and legumes.

• Support Better Decisions: Helps guide dietary choices and symptom management.

What This Test Measures

This test measures your body’s IgE antibody response to:

Peanuts
Hazelnuts

An elevated IgE response may indicate a true allergic reaction, where the immune system reacts to proteins in these foods.

Symptoms & Cross-Reactivity

Symptoms of peanut or hazelnut allergy may include:

• Swollen eyes and lips

• Itching around the mouth

• Runny nose, nasal congestion, or sneezing

• Breathing difficulties

• Hives (skin reactions)

Cross-reactivity is common in allergies.
Peanuts may cross-react with legumes such as soy, peas, beans, and lentils, while hazelnuts may cross-react with birch pollen.

A broader test covering multiple allergens can help provide a more complete overview of potential triggers.

How It Works & Important to Know

Order Your Kit: Purchase your test online.
Collect Your Sample: Take a finger-prick blood sample at home and place a few drops on the collection card.
Send It Back: Mail your sample to the laboratory.
Receive Results: Access your digital results once analysis is complete.

This method is quick, minimally invasive, and easy to perform.

Peanuts and hazelnuts can be found in many foods, including baked goods, confectionery, cereals, and prepared dishes, so awareness is important when interpreting your results.

For the most accurate results, it is recommended that you have had recent exposure to these foods, as this ensures your immune response is detectable.

ISO-Certified Lab and Analysis

Your sample is analyzed at an ISO-certified laboratory using ELISA (Enzyme-Linked Immunosorbent Assay), ensuring accurate and reliable results.

Biomarkers included

• Hazelnut: Hazelnut allergy is a type of tree nut allergy that reflects an immune response to proteins found in hazelnuts. It is a common food allergy that can cause reactions ranging from mild symptoms to severe anaphylaxis. Both raw and cooked hazelnuts can trigger this allergic reaction.
• Peanut: Peanut allergy is a common food allergy that occurs when the immune system overreacts to proteins found in peanuts, which are legumes rather than true nuts. It often begins in childhood and can cause a range of symptoms, from mild irritation to severe, life-threatening reactions such as anaphylaxis.

How to prepare

For the most accurate results, it is recommended that you have been exposed to the allergens within the last 3 months, as this ensures your immune response is detectable. 2-4 weeks before: Eat/be in contact with the items you want to GetTested for. 24 hours before: Avoid alcohol, caffeine, intense exercise and smoking.

Frequently asked questions

How does it work? / When do I get my results?

1. Order and receive your kit. 2. Perform the test. 3. Send a sample at the beginning of the week (to avoid delays). 4. Results digitally in 10–15 business days.

What is the difference between a nut allergy and a nut intolerance?

This test measures IgE antibodies, which are indicative of a true food allergy. This is different from a food intolerance test (which measures IgG antibodies) that typically relates to digestive difficulties rather than an immune system reaction.
