What makes ImmunoCAP food allergen testing special?

Years of research and trust in the scientific community

Found in over 6,000 scientific publications1 and countless health guidelines, ImmunoCAP testing is the gold standard in in-vitro allergy diagnostics2 with over 50 years of research and development.

Why use ImmunoCAP testing for patients with food allergies?

A diversity of testing options suited for a diversity of food allergies

From the most to the least common food allergens, ImmunoCAP tests offer a multitude of testing options. Browse our Lab Ordering Guide to find ImmunoCAP test codes for the laboratories you use. 


ImmunoCAP testing also offers cutting-edge allergen component test options, which measure allergic sensitization to specific proteins or carbohydrates found in whole allergens and gives you a deeper understanding of cross-reactivity, severity, and potential tolerance.

Narrow your differential diagnosis.

Food allergies can cause a wide variety of symptoms, sometimes making diagnosis difficult.4

Out of the 35% of patients who self-report having a food allergy, only 3.5% have a true clinical allergy.4

ImmunoCAP testing can help narrow your differential diagnosis and determine whether a patient's gastrointestinal symptoms may be due to allergies. 

How can ImmunoCAP testing help patients with food allergies?

Food allergy testing may help in managing other disease states.



80% of infants with severe atopic dermatitis suffer from food allergies such as milk, egg white, and sesame.5 ImmunoCAP Specific IgE testing can help provide insight on whether these symptoms are due to food allergies, non-allergic triggers, or something else. 



Patients with asthma face an increased risk of severe exacerbations if they also have food allergies,6 and testing can help you prepare patients to avoid certain triggers and construct an asthma management plan.


Nonallergic food-related diseases

ImmunoCAP Specific IgE testing aids in the diagnosis of allergic diseases.7 This is especially helpful to differentiate allergies from non-allergic conditions, such as IBS.4

How do you interpret food allergen component test results?

Let us help you with interpretation

Whether you’re a primary care provider or a specialist, interpretation guides for allergen component test results provide clear guidance on how sensitization to different types of food allergen components may influence the patient management plan.

Specific IgE blood test results should be interpreted in conjunction with the patient’s clinical history and physical examination.8-10  ImmunoCAP blood test results will indicate whether the patient is sensitized (i.e., has IgE antibodies) to specific allergens. However, sensitization to specific allergens does not always indicate a clinical allergy, as sensitization does not always result in symptoms.8,11

What are the benefits of ImmunoCAP blood testing?

Trusted across specialties, ImmunoCAP Specific IgE tests are the gold standard in in-vitro allergy diagnostics,7 which can help optimize outcomes for allergy patients.
