Understanding Lab Tests for Lemon Allergy
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
A lemon allergy occurs when the immune system mistakenly identifies proteins in lemons as harmful substances, triggering an allergic reaction. Symptoms can range from mild digestive discomfort to more severe reactions including skin rashes, respiratory issues, or gastrointestinal symptoms.
Recommended Test
Lemon (f208) IgG
This test measures IgG antibodies specific to lemon proteins in the blood. Elevated levels of these antibodies indicate that the immune system has recognized lemon as an allergen and mounted an immune response, confirming the presence of a lemon allergy.

Diagnosing Lemon Allergy Through Blood Testing
While food allergies are often suspected based on symptoms and dietary history, specific blood tests can provide objective evidence of an immune response to lemon proteins. These tests measure antibodies that the immune system produces when it encounters allergens.
Understanding Your Test Results
A positive result indicates the presence of lemon-specific IgG antibodies, suggesting an allergic sensitivity. This information can help guide dietary choices and avoidance strategies. However, the severity of symptoms doesn't always correlate directly with antibody levels, so clinical correlation with your symptoms is important.
Managing Lemon Allergy
Once a lemon allergy is confirmed through testing, the primary management strategy involves avoiding lemons and lemon-containing products. This includes checking ingredient labels carefully, as lemon can be found in many processed foods, beverages, and even some medications or supplements.
