Quick Facts
- Sample: Blood
- Fasting: No special preparation is required
- Turnaround: 3-5 business days (may take longer based on weather, holiday, or lab delays)
What's Included
This test measures allergen-specific IgE antibodies to chicken (F083 IgE Chicken) in a blood sample. IgE antibodies are produced by the immune system when it identifies specific proteins in chicken as a threat, and elevated levels can indicate sensitization to chicken.
This is a single-allergen IgE test. It reports results for chicken only and does not measure IgE to other poultry, eggs, or any other food. It does not measure IgG or any other antibody class, and it does not report on allergen components separately from whole chicken allergen.
Benefits
- Measures IgE antibody levels specific to chicken
- Uses a standard blood draw with no special preparation
- Offers a starting point for discussing chicken-related symptoms
- Provides results your healthcare provider can review with your history
- Focused, single-allergen result for chicken sensitization
Who Is This Test For?
- People who have noticed symptoms after eating chicken or chicken-based products
- People whose healthcare provider is evaluating a possible chicken sensitization
- People wanting a blood-based option to check IgE sensitization to chicken specifically
- People with a known egg allergy who want to discuss chicken with their provider
- People being evaluated for reactions that occurred after contact with chicken or its feathers

FAQ
1. What does this test measure, and how is it different from other food allergy tests?
This test measures IgE antibodies specific to chicken (F083 IgE Chicken) using a blood sample. Unlike a food allergy panel, it does not screen for other poultry, eggs, or unrelated foods, so it's narrowly focused on chicken sensitization rather than providing a broader food allergy picture.
2. Who should consider this test, and when?
Chicken-related symptoms are the main reason to consider this test, particularly for anyone who has noticed a reaction, such as skin, digestive, or respiratory symptoms, within minutes to a few hours of eating chicken or chicken-based products. Since chicken and egg yolk can share some allergens, people with an existing egg allergy who are curious about chicken may also find this test relevant to discuss with their provider. Symptom timing can vary, with most reactions occurring within two hours of ingestion, though delayed responses of four to six hours or longer are possible in some cases.
3. Do I need to fast or prepare for this test?
No special preparation is required for this test. You can have it drawn at a local lab without fasting or any other pre-test steps.
4. How quickly will I get results?
Results are typically available in 3-5 business days. This timeframe may extend due to weather, holidays, or other lab delays.
5. How should I interpret my results, and what if they are abnormal?
Interpreting this result involves more than the IgE number alone. It depends on your allergen, your symptom history, and other clinical context, since IgE sensitization does not by itself confirm a clinical food allergy or predict how severe a future reaction might be. A negative result does not guarantee chicken can be eaten without any reaction, and a positive result does not automatically mean chicken must be avoided. If your result falls outside the expected range, review it with a qualified healthcare provider, who can help place it in context and determine whether any further evaluation is appropriate.

Pre-Test preparation
No special preparation is required.
Cross-Reactivity
Cross-reactivity can occur when the immune system recognizes similar proteins shared across different allergens, sometimes producing reactions to substances beyond the one originally tested. This test measures IgE to chicken only, and it does not test for the egg proteins, other poultry, or other substances discussed below. The examples below are not an exhaustive list, and they represent possible additional considerations rather than confirmed allergies. Having a chicken IgE result does not mean you will necessarily react to any of the items listed here. Depending on your symptoms, history, or previous reactions, related allergen testing may be worth discussing with your healthcare provider.
- Egg yolk (bird-egg syndrome): Chicken serum albumin (alpha-livetin, Gal d 5) is a heat-labile protein shared between chicken tissue and egg yolk, and cross-reactivity between the two has been documented in the medical literature.
- Other poultry meats (turkey, duck, goose): Some chicken muscle proteins, including myosin light chain, have been shown to be strongly cross-reactive with corresponding proteins in other poultry species.
- Bird feathers and droppings: Sensitization to airborne avian proteins, such as those in feathers or droppings, has been associated in some individuals with cross-reactive sensitization to egg yolk and, in some cases, poultry meat.
These relationships are complex, and having sensitization to one does not mean a person will experience a clinical reaction to the others. If reactions to related allergens are a concern, additional evaluation may be considered based on your history and your healthcare provider's guidance.
