What This Test Measures
This test measures your IgE antibody levels specific to apricot (biomarker F237-IgE Apricot, also known as Prunus armeniaca) using a blood sample. IgE antibodies are produced by your immune system in response to specific proteins it identifies as harmful, and elevated levels to a specific allergen can indicate sensitization to that substance. This test evaluates sensitization to apricot specifically, and the result reflects your IgE response to this single food allergen rather than to other foods or allergen sources.
Benefits

- People wanting IgE antibody data specific to apricot to discuss with a provider
- Individuals seeking convenient blood-based testing without special preparation
- People who consume apricot-containing foods, beverages, or personal care products and want to understand their apricot-specific IgE levels

FAQ
1. What does this test measure, and how is it different from other food allergy tests?
This test measures IgE antibody levels specific to apricot, identified by the biomarker F237-IgE Apricot. It focuses only on apricot sensitization rather than testing for other fruits, foods, or allergen sources, so it is not a broader food allergy panel and does not provide information about other allergens.
2. Who should consider this test, and when?
People who have noticed symptoms after eating apricots or apricot-containing products, or who are working with a healthcare provider to evaluate a possible apricot sensitivity, may find this test relevant. It can also be useful for anyone wanting objective IgE data on apricot specifically to bring into a conversation with a provider.
3. Do I need to fast or prepare for this test?
No special preparation is required for this test. You can proceed with the standard blood draw process at a local lab without adjusting your diet, medications, or routine beforehand.
4. How quickly will I get results?
Results are typically available within 3 to 5 days, though this timeframe may extend due to weather, holidays, or other lab-related delays. You will be notified once your results are ready to view online.
5. How should I interpret my results, and what if they are abnormal?
Interpreting an IgE result depends on your specific level, your personal and family history, any symptoms you have experienced, and other clinical information, so this result should not be read in isolation. A positive result reflects sensitization to apricot but does not by itself confirm a clinical food allergy, predict how severe a reaction might be, or establish whether apricot is safe or unsafe for you to eat. If your result falls outside the expected range, review it with a qualified healthcare provider, who can help place it in context with your broader health picture and determine whether further evaluation is appropriate.

Pre-test preparation
No special preparation is required.
Cross-Reactivity
Cross-reactivity can occur when your immune system recognizes proteins in one substance that closely resemble proteins found in another, even though the two come from different foods, pollens, or plants. This test measures IgE antibodies to apricot only, and it does not test for the additional foods or pollens described below. The examples that follow are not exhaustive, and they are meant only as general educational context, not confirmed allergies or a required list of things to avoid. Depending on your symptoms, history, or prior reactions, your healthcare provider may help you consider whether related allergen testing is worth discussing.
- Birch pollen: One of apricot's key allergenic proteins is structurally similar to the major birch pollen allergen, and some people sensitized to birch pollen may also show reactivity to apricot and related fruits.
- Apple, pear, and cherry: These fruits contain proteins structurally similar to the same apricot allergen family, and cross-reactivity among them has been documented, particularly in people with birch pollen sensitization.
- Peach and almond: A separate apricot allergen, a lipid transfer protein, shares a very high degree of similarity with lipid transfer proteins in peach and almond, and cross-reactivity among these has been reported as common.
- Cherry and plum: These stone fruits contain lipid transfer proteins closely related to apricot's, and shared reactivity has been described in the medical literature.
These relationships do not mean that everyone with apricot sensitization will react to the foods or pollens above, and a positive apricot result does not predict whether related reactions will occur. If reactions to these or other allergens are a concern, your healthcare provider can help determine whether additional evaluation makes sense based on your individual history.
