Test Directory

This allergen-specific IgE antibody test quantifies an individual’s IgE response to ferret epithelium. It is an in vitro quantitative assay that is intended to be used in conjunction with other clinical information to aid in the diagnosis of allergic diseases.

While allergen-specific serum IgE testing is considered comparable to skin testing in many instances, both the American Academy of Allergy, Asthma, and Immunology and the American College of Allergy, Asthma, and Immunology recognize that allergen-specific serum IgE testing may be preferred in some clinical situations. These include 1) the presence of widespread skin disease, 2) the recent use of antihistamines or other medications that can affect the results of allergy skin tests, 3) uncooperative patients, and 4) medical history suggesting that allergen skin testing would pose a significant risk for a serious allergic reaction.

Specimen Type: Serum

Preferred Collection Container: Gold Top, Serum Separator

Alternate Collection Container: Red Top, Plain

Desired Specimen Volume: 0.3 mL

1. Collect a gold top, serum separator tube via venipuncture.

1. Separate serum from cells.
2. Transfer 0.3 mL of serum to a clear aliquot tube (screw cap).

Transport to the laboratory refrigerated.

See patient report.

A definitive clinical diagnosis of allergy should not be based on the results of any single diagnostic method, but should be made by a trained healthcare provider after all clinical and laboratory findings have been evaluated.
