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
The Spinach Allergy IgE Blood Test measures spinach-specific IgE antibodies in your blood. IgE antibodies are produced by the immune system and may be associated with allergic reactions to specific proteins in spinach. Your results can help your healthcare provider evaluate possible IgE sensitization to spinach alongside your symptoms and medical history.
This test measures IgE specific to spinach only. It does not test for other foods or allergens, and a result alone does not confirm a clinical spinach allergy.
Benefits
- Measures spinach-specific IgE antibodies in your blood
- Helps evaluate possible IgE sensitization to spinach
- Provides information to discuss with your healthcare provider
- May support evaluation when spinach-related allergic reactions are suspected
Who Is This Test For?
- People who have experienced possible allergic symptoms after eating spinach
- People evaluating a suspected allergic reaction to spinach
- People whose healthcare provider recommends spinach-specific IgE testing
- People seeking laboratory information about possible IgE sensitization to spinach

FAQ
1. What is the purpose of this test?
The test measures spinach-specific IgE antibodies in your blood to help evaluate possible sensitization to spinach. IgE antibodies are part of the immune response involved in allergic reactions. The result should be considered with your symptoms, exposure history, and other clinical information rather than used alone to confirm a spinach allergy.
2. Who should consider this test, and when?
You may consider testing if you have experienced symptoms associated with a possible spinach allergy. The source identifies symptoms ranging from hives, itching, and gastrointestinal symptoms to coughing, wheezing, swelling, or difficulty breathing. Symptoms may occur within minutes to several hours after exposure.
3. How does this test differ from other food allergy tests?
This test is specifically focused on IgE antibodies associated with spinach. It does not provide laboratory results for other foods or allergens, including other plants related to spinach.
4. Do I need to fast or prepare for this test?
No special preparation is required.
5. How quickly will I get results?
Results are typically available in 3-5 days. May take longer based on weather, holiday, or lab delays.
6. How should I interpret my results, and what if they are abnormal?
Your result provides information about spinach-specific IgE antibodies in your blood. Interpretation should consider the result alongside your symptoms, exposure history, and other relevant clinical information. A laboratory result alone does not establish whether you have a clinical spinach allergy or predict how severe a future reaction could be.
Discuss your results with a qualified healthcare provider, who can determine whether additional evaluation is appropriate.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
Pre-test preparation
No special preparation is required.
Cross Reactivity
Cross-reactivity can occur when your immune system recognizes similar proteins in different allergens. This test measures only spinach-specific IgE and does not test for the additional foods, molds, pollens, or other substances discussed below. These examples are not exhaustive, and cross-reactivity does not mean you will necessarily have a clinical reaction to another allergen.
Research has identified cross-reactive relationships involving spinach, particularly with certain molds and mushrooms. Depending on your history, symptoms, or previous reactions, related allergens may be worth discussing with your healthcare provider.
- Alternaria: A clinically recognized mold-food association involving Alternaria and spinach has been described.
- Other molds: Cross-reactive proteins involving spinach have also been studied in people sensitized to Cladosporium or Aspergillus.
- Mushrooms: Research has identified a shared cross-reactive allergen in spinach and mushrooms in mold-allergic individuals.
