Honey Bee Venom (Allergen Specific IgE)

Honey Bee Venom (i1)

Test Codes

Antrim #31860, EPIC: LAB5650, SOFT: EHB

Department

Special Testing Allergens

Specimen Collection Criteria

Collect: One Gold-top SST tube.

Twenty individual allergen assays or allergen screens can be performed on one 5 mL Gold-top SST tube. Each allergen assay requires 100 mcL of serum.

Physician Office/Draw Specimen Preparation

Let specimen clot 30-60 minutes then immediately centrifuge to separate serum from cells. Refrigerate (2-8°C or 36-46°F) the centrifuged collection tube within two hours of collection.

Preparation for Courier Transport

Transport: Centrifuged collection tube, refrigerated (2-8°C or 36-46°F).

Rejection Criteria

Plasma specimens.

Severely lipemic or hemolyzed specimens.

In-Lab Processing

Let specimen clot 30-60 minutes then immediately centrifuge to separate serum from cells. Room temperature is acceptable for a maximum of two hours.

Test Methodology

Fluorescence Enzyme Immunoassay (FEIA).

Interpretation

The allergen class may not be predictive of clinical disease in some patients. The diagnosis of allergy should be based upon patient history and clinical findings. The diagnosis of allergy should not be based upon laboratory findings alone.

Clinical Utility

A positive test result (class 1 or greater) is indicative of the presence of allergen-specific IgE and suggests an increased likelihood of allergic disease.

Clinical Disease

In the United States it is estimated that one to two million people are severely allergic to stinging insect venoms. Approximately 90 to 100 deaths occur annually from sting reactions. This number may under-represent the true total because some sting reactions are misdiagnosed as heart attacks, sunstrokes, or other acute illnesses. Death can occur without a previous history of a sting allergy. The frequency of fatal reactions due to anaphylaxis increases with age.

Prophylactic measures must be taken for those individuals who develop severe reactions to insect stings. Specific immunotherapy (hyposensitization) remains the most effective means of treatment with a 96% success rate (1).
