| Item | Process |
|---|---|
| Specimen | 5 mL blood in plain tube. |
| Method | Immunoassay |
| Reference Interval | Methodology dependent. |
| Application | Detection of specific IgE antibodies as an adjunct to allergy investigation where skin prick allergen testing is contraindicated, or unsuccessful, or when further interpretation is required. |
| Interpretation | A positive result to multiple aeroallergens indicates atopy. In association with a suggestive clinical history, a positive result to a specific allergen supports a causative role for that allergen. |
