The Tangerine Allergy Test measures immunoglobulin E (IgE) antibodies against tangerine, a citrus fruit. Citrus allergies are uncommon, but when they occur symptoms can range from mouth itching and hives to more serious reactions. This single-allergen blood test helps assess whether tangerine specifically may be a trigger for symptoms that appear after eating it or drinking tangerine juice. Results are interpreted with your clinical history, and because citrus fruits share some proteins, your provider may consider other citrus tests as well.

• Tangerine-specific IgE Measures IgE antibodies that react to tangerine proteins.

• People who develop itching, hives, or swelling after eating tangerine or drinking tangerine juice.
• Individuals with a suspected citrus allergy who want to check tangerine specifically.
• People who react to some citrus fruits but tolerate others and want clarification.
• Anyone with pollen allergies and related oral symptoms after fresh fruit.
• Caregivers investigating reactions in children after citrus consumption.

• No fasting is required.
• Take your usual medications unless a healthcare provider instructs otherwise.
• Only pause antihistamines before testing if your provider specifically asks, as they may influence some allergy results.
• Note which citrus fruits and symptoms you have experienced to help interpret the result.

The report shows the level of tangerine-specific IgE antibodies. A positive or elevated result may indicate sensitisation to tangerine, while a negative result makes allergy less likely. Because citrus fruits share some proteins, sensitivity to tangerine may sometimes accompany sensitivity to another citrus fruit, though this is not guaranteed. IgE testing cannot measure how severe a future reaction might be. Review your result with a healthcare provider, who can combine it with your history and decide on next steps.
