Description
The Food IgE Panel Allergy with REFLEX Blood Test is a diagnostic test that measures IgE (immunoglobulin E) antibodies in the blood in response to a set of common food allergens. This test helps determine whether someone has a food allergy and provides further insight when certain foods test positive by reflexively analyzing specific allergen components.
Purpose of the Test:
- To identify IgE-mediated food allergies, which can cause symptoms like hives, swelling, difficulty breathing, gastrointestinal issues, and even anaphylaxis.
- To enhance diagnostic accuracy through reflex testing, which analyzes individual allergenic components if a positive result is found for specific foods like peanut, milk, or egg white.
How the Test Works:
- Blood Sample Collection:
- A blood sample is taken, typically from a vein in the arm, and sent to the lab for analysis.
- IgE Testing:
- The test measures IgE antibodies specific to each food listed. Elevated IgE levels indicate a likely allergic response.
- Reflex Testing:
- If the result is positive for peanut, milk, or egg white, additional testing is automatically performed to break down the allergy into specific components (e.g., Ara h 1, Ara h 2 for peanuts), which helps assess the severity and risk of reaction.
Foods Tested in This Panel:
- Clam IgE
- Cod Fish IgE
- Corn IgE
- Scallop IgE
- Sesame Seed IgE
- Shrimp IgE
- Soybean IgE
- Walnut IgE
- Wheat IgE
- Peanut IgE with Reflex Component Testing
- Milk IgE with Reflex Component Testing
- Egg White IgE with Reflex Component Testing
Fasting Not Required:
You do not need to fast before this test. Normal eating and drinking are allowed prior to the blood draw.
Conclusion:
The Food IgE Panel Allergy with Reflex Blood Test is a valuable diagnostic tool for identifying food allergies and understanding their severity. The reflex component testing for peanut, milk, and egg white adds an extra layer of insight, helping healthcare providers create more accurate and personalized treatment plans.
