This page explains the citrus fruit allergy test panel, what it measures, and how to arrange it. The Citrus Fruit Allergy Test Panel is a blood test that checks for allergic sensitization to proteins found in citrus fruits. It is usually ordered when a person reports symptoms such as itching, hives, or oral tingling after eating or handling citrus, or when a clinician wants to clarify a suspected food allergy.

The Citrus Fruit Allergy Test Panel is a blood test that checks for allergic sensitization to proteins found in citrus fruits. It is usually ordered when a person reports symptoms such as itching, hives, or oral tingling after eating or handling citrus, or when a clinician wants to clarify a suspected food allergy.
What it measures
- Orange-specific IgE — Antibodies that may indicate sensitization to orange proteins.
- Lemon-specific IgE — Antibodies that may indicate sensitization to lemon proteins.
- Lime-specific IgE — Antibodies that may indicate sensitization to lime proteins.
- Grapefruit-specific IgE — Antibodies that may indicate sensitization to grapefruit proteins.
- Tangerine-specific IgE — Antibodies that may indicate sensitization to tangerine or mandarin proteins.
Who it is for
A primary care clinician, allergist, or immunologist typically orders this panel after reviewing symptoms and history. It may also be ordered when other allergy testing has not explained a reaction.
Preparation
No fasting is required. Tell the clinician about any medications, especially antihistamines, because they may affect some allergy test results.
Results and what they mean
Results are reported as antibody levels for each citrus fruit, often with a reference range. A clinician interprets these values alongside symptoms and history, because a positive result alone does not always mean a true allergy. This is general information, not medical advice; discuss your results with a qualified healthcare professional.

Frequently asked questions
Does a positive result mean I am allergic to citrus?
Not necessarily. It means your blood contains antibodies that may be associated with sensitization. A clinician uses your symptoms and history to decide whether it reflects a true allergy.
Do I need to stop eating citrus before the test?
Usually no. Follow any instructions from your clinician, who may ask you to avoid certain foods only if needed for other testing.
Can this test predict how severe a reaction will be?
No. Blood test levels do not reliably predict the severity of a future reaction. Your clinician will assess your overall risk.
How long do results take?
Results are typically available within 1 to 3 business days after the sample is received by the laboratory.
