ImmunoCAP™ Specific IgE tests

Improve patient outcomes with trusted allergen diagnostics

One blood test can help improve symptom management for patients with allergies.

For laboratorians interested in adding ImmunoCAP to your test portfolio, explore the ImmunoCAP product catalog.

What is ImmunoCAP Specific IgE blood testing?

A convenient blood test for all

The gold standard in in-vitro allergy diagnostics, ImmunoCAP tests are trusted across specialties to optimize outcomes in patients with allergies.1

Learn more about ImmunoCAP Specific IgE testing.

The sum of 50+ years of allergy diagnostic research

Backed by years of research and analyzed on reliable and automated Phadia Laboratory Systems, ImmunoCAP Specific IgE assays deliver trusted results by using quality allergen preparations, fluoroenzyme immunoassay technology, and methods that detect even low levels of sensitization.4

Endorsed by the scientific community.

Documented in more than 6,000 peer-reviewed publications and referenced in health guidelines across the world.4

“The ImmunoCAP system considered as the ‘gold standard’ for the in vitro diagnosis of allergic conditions.”1

- European Journal of Allergy and Clinical Immunology

“Accurate. Precise. Sensitive.2

- Journal of Allergy and Clinical Immunology

“ImmunoCAP is the only test accurate and reliable enough… for advanced investigations of patients with IgE-mediated allergy… [as well as being] well suited for use in primary care ”3

- Expert Review of Molecular Diagnostics

Why use ImmunoCAP blood testing?


For atopic patients, correct diagnoses increase from as low as 30% up to 97% when using specific IgE testing alongside clinical history and physical examination.5

Broadly accessible

Irrespective of age, skin condition, antihistamine use, or pregnancy, ImmunoCAP Specific IgE tests can be used for a variety of patient types.6,7

Zero risk

Unlike skin-prick testing, blood testing offers no risk of anaphylaxis to the patient.6,7

Specialized testing, not just for specialists

ImmunoCAP Allergen Component testing aids in patient management by helping to identify which molecules a patient may be reacting to in whole allergens, such as peanuts, tree nuts, milk, eggs, pets, and more.8

Interpretation guides

Whether you’re a primary care provider or a specialist, ImmunoCAP Specific IgE test interpretation guides provide in-depth and clear information that helps to guide patient management decisions.

*Specific IgE blood test results should be interpreted in conjunction with the patient’s clinical history and physical examination.10,11  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.12

ImmunoCAP Specific IgE FAQ

Can I order this test in a primary care setting?

Access to testing may vary by location; however, most primary care providers can order ImmunoCAP testing. In fact, primary care providers are at the forefront of many allergic disease states. As such, they have the ability to help patients quickly by ordering ImmunoCAP testing during an initial visit.

In addition to primary care, any health care provider who normally orders laboratory testing can order ImmunoCAP testing.

Find your preferred laboratory’s codes.

How much blood is needed to run an ImmunoCAP Specific IgE test?

The amount of blood required is dependent upon the number of allergens ordered. Speak to a representative at your laboratory to determine the amount of serum needed.

What is the difference between ImmunoCAP Specific IgE tests and other allergy diagnostics?

ImmunoCAP assays contain technology specifically made for allergy diagnostics. Inside every ImmunoCAP test is a three-dimensional cellulose structure that provides more surface area for binding, leading to high assay sensitivity as well as accurate, precise, and sensitive results.2

What’s the difference between whole allergens and allergen components?

Allergen components are just that; components of a whole allergen. Like a puzzle piece, they are a part of a bigger picture and allow for a deeper understanding of what a patient may specifically be sensitized to in a whole allergen.

Varying by location, some laboratories offer reflex testing for a number of whole allergens. Therefore, if a patient tests positive for a sensitization to a whole allergen, the test will reflex and test for its available allergen components. This additional information may help to determine patients at risk of systemic reactions or in other cases tolerability of versions of a given allergen.8 Together with patient history this provides insights when developing an optimized management plan.8

Is the ImmunoCAP test a radioallergosorbent test (RAST)?

While RASTs rely on radioactive tagging, ImmunoCAP tests use fluorescently labeled detection antibodies to measure levels of specific IgEs. The intensity of light emitted when binding to specific IgEs is then measured by a Phadia Laboratory System, which translates the data into results.
