Allergen Profile With Total IgE, Respiratory−Area 14

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

The test evaluates for a range of allergens specific to Central California, ensuring relevant results for patients in that area. It is also useful when an individual is taking medications that might interfere with skin testing, or when skin testing has not provided satisfactory remission of symptoms.

Limitations

The test may not detect all allergic responses, and its results might be affected by concurrent medications, particularly if they affect IgE levels. The presence of cross-reactivities among inhalant allergens can sometimes lead to positive results that are not clinically significant. As with all tests, results should be interpreted within the context of the overall clinical picture and in conjunction with other diagnostic procedures.
