What this test is
This test looks for specific antibodies or skin reactions that indicate an allergy to lemon. It may also include testing for other citruses such as orange, lime, grapefruit, and tangerine. The results help a clinician understand whether your symptoms are related to citrus exposure.
What it measures
- Lemon-specific IgE — Reflects allergic sensitization to lemon proteins.
- Orange-specific IgE — Reflects allergic sensitization to orange proteins.
- Lime-specific IgE — Reflects allergic sensitization to lime proteins.
- Grapefruit-specific IgE — Reflects allergic sensitization to grapefruit proteins.
- Tangerine-specific IgE — Reflects allergic sensitization to tangerine proteins.
What the test involves
A sample is usually collected through a standard blood draw from a vein in your arm. In some cases, a skin prick test may be performed instead, where a small amount of allergen is placed on your skin.
Why it is often ordered
A clinician may order this test if you have had allergic symptoms after eating or handling lemons or other citrus fruits. It can help identify triggers and guide recommendations for avoiding certain foods.
Preparation
Preparation is generally minimal, but you should follow the specific instructions provided by the collection lab. This may include avoiding certain medications or fasting for a period before the test.
How results are reported
Results are reported as positive or negative, or as a level of reactivity, depending on the method used. Reference ranges vary by laboratory, so your results should always be interpreted in the context of the lab's own standards.

FAQ

What symptoms might prompt a lemon allergy test?
Symptoms can include itching, hives, swelling, stomach upset, or breathing difficulty after consuming or touching lemons. If you experience these, a clinician may recommend testing to confirm an allergy.
Is this test the same as a citrus allergy panel?
A citrus allergy panel typically includes lemon along with other common citruses. This test may be part of such a panel or ordered on its own, depending on your clinician's assessment.
How long does it take to get results?
Results are usually available within a few business days, though this can vary by laboratory. Your clinician will discuss the findings with you once they are ready.
Can I have a lemon allergy without reacting to other citruses?
Yes, it is possible to be allergic to lemon alone, though cross-reactivity with other citruses is common. Testing can help clarify which specific fruits trigger your symptoms.
