Upper respiratory disorders Asthma management Food allergens ImmunoCAP testing

Powering better patient management through simplified allergy testing

Allergies, respiratory infections, and asthma often present with similar symptoms, making them difficult to differentiate. Being able to rule in or rule out allergies as the cause of your patients’ symptoms can help inform better treatment decisions. The Centers for Disease Control and Prevention (CDC) also recommends allergy testing for patients with asthma, to help close gaps in care.1

Simplify allergy testing and patient management with ImmunoCAP™, an easy, reliable IgE blood test. It quantitatively measures specific IgE antibody levels and identifies allergic sensitivities.

IgE blood testing during SARS-CoV-2 (COVID-19)

Patients with underlying conditions, including moderate to severe asthma, might be at an increased risk for severe illness from COVID-19.2 Identifying allergic triggers in order to control asthma is more important than ever.

Identifying upper respiratory disorder allergy triggers

Upper respiratory disorders (URDs), including rhinitis, sinusitis, and allergic rhinitis, affect tens of millions of Americans.3 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 allergy4
  • Results from specific IgE blood tests like ImmunoCAP play a key role in making the correct diagnosis5
  • Patients with the following should be tested: recurrent or chronic URD; unseasonal allergy-like symptoms; seasonal or perennial allergy-like symptoms; recurrent otitis media; exogenous asthma and other conditions in which IgE mediation is suspected
  • Most respiratory-specific IgE blood testing profiles are targeted to their geographic area, including regional panels

Better manage asthma by knowing the triggers

Asthma and allergy go hand in hand, as multiple allergic triggers can add up to asthma symptoms. ImmunoCAP can help you identify these triggers, reduce care gaps, and help you and your patients better control their asthma.

  • Costs for patients with uncontrolled asthma are double those for patients whose asthma is well controlled6
  • Up to 90% of children and 60% of adults with asthma have allergic sensitivities7,8
  • The CDC recommends allergy testing for children and adults with persistent asthma; allergy testing can also be considered for persons with intermittent asthma1
  • The National Institutes of Health also recommends allergy testing for successful long-term management of asthma9
  • Testing for allergy sensitivities in patients with asthma can help reduce inappropriate referrals and improve patient engagement and outcomes

Detect sensitivities with food allergen component testing

Whole allergens and allergen components can help you diagnose food allergies, allowing you to prepare a more comprehensive management plan. Determine which proteins your patients are sensitive to with ImmunoCAP allergen component testing.

  • Peanut: detecting sensitivities to the whole peanut can help you determine the likelihood of a systemic reaction; 77.6% of patients sensitive to peanut may not be at risk for a systemic reaction10
  • Egg: determining whether your patient is sensitive to egg white can help you predict the likelihood of reaction to products baked with egg, as well as allergy persistence; 70% of children with egg allergy do not react to baked egg11
  • Milk: determining how sensitive your patient is to cow’s milk can help you predict the likelihood of a reaction to baked goods, along with allergy persistence; 75% of children with milk allergy do not react to baked milk12
  • Tree nut: walnut and cashew allergies are potentially life-threatening, increasing in prevalence and rarely outgrown,13-15 and cashew nut-sensitive patients have a risk of experiencing severe allergic reactions16

Staying under-threshold for better patient management

From animal dander to pollens, allergens often add up, as every patient has a different level at which they show symptoms. When that level is crossed, the combination of allergens turns into symptoms.17,18 ImmunoCAP offers a full range of allergen testing.

  • Allergies to dogs and cats affect 10%–20% of the population worldwide19
  • Over 49 million Americans are sensitive to dog and/or cat allergens20,21
  • Whole allergens help you diagnose pet allergy, allowing you to prepare a more comprehensive management plan
  • Quest Diagnostics also offers a full range of indoor and seasonal allergen testing, including house dust mites, molds (indoor and outdoor), and pollens, among others
