Allergen Profile With Total IgE, Respiratory−Area 18

Clinical Use

Use

Detect possible allergic responses to various substances in the environment (see Test Includes) and evaluate for hay fever, asthma, atopic eczema, and respiratory allergy. The quantitative allergen-specific IgE test is indicated (1) to determine whether an individual has elevated allergen-specific IgE antibodies; (2) if specific allergic sensitivity is needed to allow immunotherapy to be initiated; (3) when testing individuals for agents that may potentially cause anaphylaxis; (4) when evaluating individuals who are taking medication (eg, long-acting antihistamines) that may interfere with other testing modalities (eg, skin testing); (5) if immunotherapy or other therapeutic measures based on skin testing results have not led to a satisfactory remission of symptoms; (6) when an individual is unresponsive to medical management where identification of offending allergens may be beneficial.

Special Instructions

Use this test when standard skin testing results have not led to satisfactory remission of symptoms or when individuals are unresponsive to medical management and identification of specific allergens is beneficial.

Limitations

The test may not capture all possible allergens, and it is limited to the allergens listed under Area 18: Alaska. In cases where additional allergens are suspected outside of this panel, further testing would be necessary. Another limitation includes potential variability in test results due to interference from medications such as long-acting antihistamines.
