Understanding Lab Tests for Eosinophilic Esophagitis
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Eosinophilic esophagitis (EoE) is a chronic immune system disease where eosinophils, a type of white blood cell, build up in the esophagus causing inflammation and difficulty swallowing. While EoE is primarily diagnosed through endoscopy and tissue biopsy, blood testing plays a crucial supporting role in identifying potential triggers that may be contributing to the condition.
Top Recommended Test
Allergen Specific IgE Cream Cheese
This test detects IgE antibodies specific to cream cheese. High levels of cream cheese-specific IgE could suggest that cream cheese is a contributing allergen triggering the allergic reaction that causes eosinophils to build up in the esophagus.

Why Blood Testing is Important for Eosinophilic Esophagitis
There is no single blood test to diagnose eosinophilic esophagitis itself. However, blood testing is fundamental for identifying specific food and environmental allergens that may be triggering the immune response. This information is essential for developing an effective treatment plan, which often involves eliminating trigger substances from the diet or environment.
Other Relevant Tests
Food Specific IgG Buckwheat
This test measures IgG antibodies specific to buckwheat. Since eosinophilic esophagitis is a chronic immune system disease caused by reactions to certain foods, including potentially buckwheat, an IgG test can help identify potential dietary triggers that may be contributing to the condition.

Allergen Specific IgG Goose Feathers
This test detects IgG antibodies specific to goose feathers. Since eosinophilic esophagitis can be triggered by environmental allergens, the presence of goose feather-specific IgG antibodies could potentially indicate that this allergen is contributing to the disease and inflammatory response.

Allergen Specific IgEÂ Tilapia
This test measures IgE antibodies specific to tilapia fish. Food allergies are commonly linked to eosinophilic esophagitis, and if a patient has elevated levels of tilapia-specific IgE, it might suggest that tilapia is a trigger food that should be eliminated from the diet.

Understanding IgE and IgG Testing
IgE antibody tests detect immediate allergic reactions and are particularly useful for identifying foods that may cause acute symptoms. IgG antibody tests can help identify delayed sensitivity reactions that may contribute to chronic inflammation. Both types of testing provide valuable information for managing eosinophilic esophagitis through targeted avoidance of trigger substances.
Important Considerations
The information here is for educational purposes only and is not a substitute for professional medical advice. Always consult with a healthcare provider for diagnosis and treatment. Definitive diagnosis of eosinophilic esophagitis requires endoscopy and biopsy, but allergen testing can provide crucial information for treatment planning.
