Allergen Profile With Total IgE, Respiratory−Area 13

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

This test includes a comprehensive profile of allergens specific to the Southern California coastal region, which can aid in targeted immunotherapy approaches. Coordination with the laboratory and timely specimen submission is advised to ensure accurate results.

Limitations

The test is limited to detecting specific IgE antibodies and may not capture all clinical manifestations of allergies. False negatives can occur if the specific allergen is not included in the profile. Furthermore, IgE levels can be influenced by factors such as concurrent medications and transient infections, and results should be interpreted in the clinical context.
