A lemon allergy blood test checks for specific IgE antibodies that your immune system may make against proteins in lemons. It is ordered when someone has had allergic symptoms after eating or handling lemons or other citrus, and the cause is unclear.
What it measures
- Lemon-specific IgE — Amount of antibody directed at lemon proteins.
- Total IgE — Overall allergy antibody level, sometimes used for context.
- Citrus cross-reactive markers — Proteins shared with other citrus fruits that may explain reactions.
- Component allergens (if done) — Individual lemon proteins to help assess risk.
Who it is for
Primary care clinicians, allergists, or dermatologists typically order this test when a lemon allergy is suspected based on symptoms or a food diary.
Preparation
No fasting or special preparation is needed. Tell your clinician about all medications, especially antihistamines, as they may affect results.
Results and what they mean
Results are reported as a number or class for each marker, often alongside a reference range. A clinician interprets these in the context of your symptoms and history; a positive result alone does not confirm an allergy. This is general information, not medical advice.

Frequently asked questions
Do I need to avoid lemons before the test?
No, you do not need to avoid lemons unless your clinician tells you otherwise.
Can this test tell me if my reaction is severe?
It can suggest sensitivity, but it cannot predict how severe a future reaction will be. Your clinician will consider your history.
What if my result is positive but I have no symptoms?
A positive result without symptoms may be a false positive. Your clinician will help decide what it means for you.
How long does it take to get results?
Typically 1-3 business days after the blood sample is collected.
