Tests that measure Fel d 2 e220 IgE

Respiratory Allergy Panel Region VII with Reflexes: MI MN WI

Laboratory
Quest Diagnostics
Test code
10648
Specimen
Serum
Fasting
Not stated as required

What the laboratory says this test is for

Up to 90 percent of children and 60 percent of adults with asthma have underlying allergies that trigger their asthma.1,2 Commonly, these allergies are to trees, grasses, molds, and animals. Allergy respiratory IgE blood tests aid in the diagnosis of allergic diseases such as asthma, allergic rhinitis, conjunctivitis, atopic dermatitis, and urticaria. In this panel, when whole allergen dog/cat protein extract is found to be positive, the dog and/or cat dander component panel, which uses individual recombinant proteins from dogs and cats, is automatically run since this improves specificity compared to animal extract assays and helps differentiate an actual dog and/or cat allergy from a cross-reactive pet allergy.⁠⁠⁠⁠⁠⁠⁠1. Allen-Ramey F, et al. J Am Board Fam Pract 2005;18(5):434-439.2. Host A, Halken S. Allergy 2000;55:600-608.

Childhood and Tree Nut Allergy Panel with Reflex to Components

Laboratory
Quest Diagnostics
Test code
36766
Specimen
Serum
Fasting
Not stated as required

What the laboratory says this test is for

Up to 90 percent of children with asthma have underlying allergies that trigger their asthma.1,2 Many things like environmental and food elements can trigger allergic reactions in children. Specific IgE serological tests aid in the diagnosis of allergic disease. In this profile, when a whole allergen protein extract is found to be positive, the respective component panel, which uses individual recombinant or purified proteins, is automatically run. Component panels improve specificity, provide the clinician with more detailed information for assessing level of risk, and help target effective management.1. Allen-Ramey F, et al. J Am Board Fam Pract 2005;18(5):434-439.2. Host A, Halken S. Allergy 2000;55:600-608.

Cat Dander Component Panel

Laboratory
Quest Diagnostics
Test code
10558
Specimen
Serum
Fasting
Not stated as required

What the laboratory says this test is for

Like respiratory allergies, animal allergies pose a significant risk for the development of asthma and rhinitis. Blood IgE tests using whole allergen extracts from cats provide a sensitive screening method to diagnose pet sensitization. In addition, the cat dander component panel is an IgE blood test using individual recombinant proteins from cats, improving specificity compared to animal extract assays. Thus, the cat dander component panel helps differentiate an actual cat allergy from a cross-reactive pet allergy.
