Understanding Lab Tests for Orange Allergy
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
An orange allergy is a food allergy that occurs when the immune system mistakenly identifies proteins in oranges as harmful substances. This can trigger various symptoms ranging from mild digestive discomfort to severe allergic reactions. Specialized blood testing can help identify this specific food sensitivity.
Recommended Test
Food Specific IgG Allergy (Pediatric) Panel
This comprehensive panel measures IgG antibodies specific to various foods, including oranges. Elevated orange-specific IgG antibodies can indicate an immune response to orange proteins, which may be associated with allergic symptoms such as skin rashes, gastrointestinal discomfort like stomach cramps, or more severe reactions including respiratory symptoms like difficulty breathing.

Diagnosing Orange Allergy Through Blood Testing
While food allergies are often suspected based on symptoms and dietary history, blood tests that measure specific antibodies can provide valuable confirmation. These tests detect the immune system's response to orange proteins, helping to establish a definitive diagnosis and guide dietary management.
Understanding Your Results
Elevated IgG antibodies to oranges in the blood test results may suggest that your immune system has been exposed to and is reacting to orange proteins. This information, combined with your symptom history, can help healthcare providers develop an appropriate management plan, which may include dietary modifications or avoidance strategies.
