Allergen Profile With Total IgE, Respiratory−Area 1

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 includes allergens commonly found in the geographic area defined as Area 1, which encompasses states in the northeastern United States. Collection in a red-top tube or gel-barrier tube is required, and the serum specimen must be handled according to the defined stability requirements.

Limitations

This test may not detect all potential allergens, and negative results do not rule out the possibility of allergies. High levels of IgE may not be specific to particular allergens and can be seen in other atopic conditions. Test results should be interpreted in conjunction with the patient's clinical history and other diagnostic tests.
