Test Codes

EPIC: LAB5694, SOFT: EPLNS

Department

Special Testing Allergens

Instructions

This multi-allergen IgE antibody assay includes the following allergen screens: Grasses 1, Grasses 2, Trees 1, Trees 2, Weeds 1, and Weeds 2.

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.

Interpretation

This multi-allergen IgE antibody assay includes the following allergen screens: Allergen Grasses 1, Allergen Grasses 2, Allergen Grees 1, Allergen Trees 2, Allergen Weeds 1, and Allergen Weeds 2.

Clinical Utility

Positive assay results indicate a high probability of allergic disease induced by one or more of the allergens present in the multi-allergen panel. Negative assay results effectively rule out allergy induced by those allergens.
