EPIC: LAB3049, SOFT: ETRO, Antrim #31494
Department
Immunology
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
Positive assay results indicate a high probability of allergic disease. Negative assay results effectively rule out allergy induced by those allergens.
