Quick Facts
- Sample: Blood
- Fasting: No special preparation is required.
- Turnaround: 2-5 business days. May take longer based on weather, holiday, or lab delays.
What This Test Measures
This test measures IgE (immunoglobulin E) antibodies specific to peaches in a blood sample. The biomarker evaluated is whole peach allergen IgE, reflecting your immune system's overall antibody response to peach proteins rather than a breakdown by individual peach component. It does not separately identify sensitivity to specific peach proteins on its own, and it does not measure IgG or any other antibody class. Results reflect IgE sensitization to peach and are intended to support, not replace, evaluation by a qualified healthcare provider.
Benefits
- Measures peach-specific IgE antibody levels from a single blood draw.
- Provides objective lab data to discuss with your healthcare provider.
- Convenient blood test with no special preparation required.
- Useful data point for evaluating suspected peach-related symptoms.
- Results delivered online within the stated turnaround window.
Who Is This Test For?
- Individuals who have noticed symptoms after eating peaches.
- People experiencing tingling, swelling, or itching after peach exposure.
- Individuals with digestive symptoms, such as nausea or diarrhea, after eating peaches.
- People who want objective IgE data to discuss with a healthcare provider.
- Individuals working with a provider to help evaluate suspected peach reactions.

FAQ
1. What does this test measure, and how is it different from other food allergy tests?
This test measures peach-specific IgE antibodies in blood, using the biomarker F095-IgE Peach. It is a single food allergen test focused only on peaches, not a broader food allergy panel, and it does not test IgG antibodies or other foods. Because it evaluates whole peach allergen rather than individual peach protein components, it differs from component-resolved diagnostic tests that isolate specific proteins.
2. Who should consider this test, and when?
People who have noticed symptoms, such as mouth tingling, swelling, hives, or digestive discomfort, after eating or handling peaches may find this test relevant. It may also be considered after a suspected reaction where a healthcare provider wants objective IgE data as part of a broader evaluation. This test alone does not diagnose a clinical peach allergy.
3. Do I need to fast or prepare for this test?
No special preparation is required for this test. You can schedule your blood draw at a local lab without fasting or adjusting your diet beforehand, unless your healthcare provider gives you other instructions.
4. How long will it take to get my results?
Results are typically available in 2-5 business days after your sample is collected. This timeframe may take longer depending on weather, holidays, or other lab delays, and results are delivered to you online once ready.
5. Can this test identify which specific peach protein I may be sensitive to?
No. This test measures overall IgE reactivity to peach as a whole allergen rather than distinguishing between individual peach proteins. Different peach proteins are associated with different patterns of reaction in the broader medical literature, but this particular test does not break results down by protein component.
6. How should I interpret my results, and what if they are abnormal?
Interpreting your result depends on the level detected, your symptom history, and other clinical information your healthcare provider may consider, since a positive IgE result reflects sensitization and does not by itself confirm a clinical peach allergy or predict how severe a reaction might be. A negative result does not guarantee that peach can be consumed without any reaction. If your result falls outside the expected range, review it with a qualified healthcare provider, who can help determine whether further evaluation is appropriate; this test does not provide a diagnosis or treatment recommendation on its own.

Pre-test preparation
No special preparation is required.
Cross-Reactivity
Cross-reactivity can occur when the immune system recognizes proteins in other foods, pollens, or substances that are structurally similar to peach proteins. This test measures only peach-specific IgE and does not test for the additional items discussed below. The examples that follow are not an exhaustive list, and they represent possible additional considerations rather than confirmed allergies. Having a documented cross-reactive relationship does not mean a person will necessarily experience a clinical reaction to another listed item. Depending on your symptoms, history, or previous reactions, discussing related allergen testing with your healthcare provider may be worth considering.
Other Rosaceae fruits (apple, cherry, plum, apricot): cross-reactivity has been reported due to shared lipid transfer proteins and other structurally similar proteins.
Birch pollen: individuals sensitized to birch pollen may show cross-reactive IgE to a Bet v 1-related peach protein, sometimes producing oral allergy syndrome symptoms.
Other lipid transfer protein-containing foods (walnut, hazelnut, peanut): cross-reactivity has been reported among foods that share lipid transfer protein structures with peach.
Cypress pollen: some sensitized individuals have shown associated reactivity linked to a peach marker protein, though this relationship is less broadly established than others listed here.
