Powering affordable care through clinically reliable allergy testing solutions
Similar symptoms make it difficult to differentiate between allergies, asthma, and respiratory infections. Accurately determining whether allergies are the cause of patients’ symptoms can inform appropriate treatment. Allergy testing can help your patients know what exposures to avoid, and just as important, which ones are safe. From objective results to avoiding potential skin discomfort from a scratch test, a simple blood test can improve patient management and outcomes.

Deliver a diagnosis—Objective numerical results bring clarity to over 400 individual allergens including nuts and foods, as well as regional respiratory allergens.

Get timely answers—Rather than dedicating office resources to scratch tests, allergy blood testing allows providers to assess allergen sensitivities, often without waiting to refer patients to a specialist.

Prioritize patient comfort—Patients don’t have to wait for a skin rash to clear before or after sampling, and a single blood draw can be conducted more quickly and comfortably than a skin allergy test.

Reduce risk of a reaction—Allergy blood testing carries no severe risk of allergic reaction, and patients can continue use of allergy medications while the sample is collected and tested.

Simplify allergy testing and patient management with ImmunoCAP™, an easy, reliable IgE blood test

It quantitatively measures specific IgE antibody levels and identifies allergic sensitization.
Blood testing for response to specific allergens can determine a patient’s tolerance level to allergy triggers. When used to create an individualized management plan, patients can enjoy peace of mind without fear of a systemic reaction. 

Upper respiratory disorders, including rhinitis, sinusitis, and allergic rhinitis, affect tens of millions of Americans.1 Because the cause of URD symptoms may be viral, bacterial, or allergic, a definitive diagnosis is essential to determine appropriate treatment.

Nearly two-thirds of patients prescribed antihistamines for their reported allergic rhinitis have symptoms that are not due to allergy2

Asthma and allergy go hand in hand, as multiple allergic triggers can add up to asthma symptoms. This is 1 reason why the CDC recommends allergy testing for patients with asthma, to help close gaps in care.3 ImmunoCAP™ can help you identify specific triggers, reduce care gaps, and help you and your patients better control their asthma symptoms. Testing for allergy sensitivities in patients with asthma can help reduce referrals and improve patient engagement and outcomes.

Costs for patients with uncontrolled asthma are double those for patients whose asthma is well controlled4

Up to 90% of children and 60% of adults with asthma have allergic sensitivities5,6

Blood testing for response to whole allergens and allergen components can help you diagnose food allergies, allowing you to prepare a more comprehensive management plan. Determine to which proteins your patients are sensitized through ImmunoCAP allergen component testing, and use this to help assess likelihood of allergic reaction.

Peanut: 77.6% of patients sensitive to peanut may not be at risk for a systemic reaction7

Egg: 70% of children with egg allergy do not react to baked egg8

Milk: 75% of children with milk allergy do not react to baked milk9

Tree nut: walnut and cashew allergies are potentially life-threatening, increasing in prevalence and rarely outgrown10-12

From animal dander to pollens, allergens often add up as each patient has a different level at which they show symptoms. When that level is crossed, the combination of allergens turns into symptoms.13,14 Blood testing for response to whole allergens helps you diagnose pet allergies, as well as other indoor and outdoor allergies, and to prepare a more comprehensive management plan. ImmunoCAP offers a full range of allergen testing.

Over 49 million Americans are sensitive to dog and/or cat allergens15,16

Quest Diagnostics also offers a full range of indoor and seasonal allergy testing, including house dust mites, molds (indoor and outdoor), and pollens, among others

Quest Diagnostics is working to provide you with the insights you need to help your patients better manage allergy triggers.
