• Allergy Trigger? Simplify KNOWING for Patients With Asthma

    Information provided by Quest Diagnostics

    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

    Identifying upper respiratory disorder allergy triggers
    Upper respiratory disorders (URDs), including rhinitis, sinusitis, and allergic rhinitis, affect tens of millions of Americans.2 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 allergy.3
    • Results from specific immunoglobulin E (IgE) blood tests like ImmunoCAP play a key role in making the correct diagnosis.4
    • 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 controlled.5
    • Up to 90% of children and 60% of adults with asthma have allergic sensitivities.6,7
    • The CDC recommends allergy testing for children and adults with persistent asthma; allergy testing can also be considered for persons with intermittent asthma.1
    • The National Institutes of Health also recommends allergy testing for successful long-term management of asthma.8
    • Testing for allergy sensitivities in patients with asthma can help reduce inappropriate referrals and improve patient engagement and outcomes.

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