What does this test include?
The panel measures specific IgE to 20 individual inhalant allergens from grasses, trees, weeds, mites, animals, and molds, plus controls for certain cross-reactions.
Why might it be ordered?
- For seasonal or year-round nasal, eye and respiratory symptoms.
- To target likely airborne allergens and discuss targeted measures or immunotherapy.
What sample is needed?
A healthcare professional collects a venous blood sample. Depending on the method, the laboratory uses serum or plasma.
How should you prepare?
Fasting is usually not required. Describe your symptoms, the possible exposures and how soon each reaction began. Tell the laboratory about all medicines, hormone treatments, vitamins and supplements you take. Do not stop or change treatment unless your clinician tells you to. Follow any instructions about fasting and the time of collection.
How are the results reported?
The result for each component indicates IgE sensitization. Significance is compared with season, site of contact and symptoms. Detectable specific IgE indicates sensitization, not necessarily clinical allergy. The results should match actual post-exposure symptoms.
