Check and manage Lemon Allergy
A Lemon IgG blood test looks for IgG antibodies to lemon. IgG antibodies are immune proteins that can rise after exposure.
A higher result may suggest an immune response to lemon. Your symptoms, timing, and health history still matter.
Testing and monitoring matter because food reactions can be confusing. Results can help you discuss patterns, avoid needless food limits, and spot when symptoms need medical care.

What is Lemon Allergy?
If lemon seems to trigger symptoms, your body may be reacting to proteins or natural compounds in citrus. A Lemon IgG result can show an immune response, but it does not prove a dangerous allergy by itself.
Food reactions can involve the skin, mouth, stomach, or breathing. A clinician can help compare your result with real symptoms.
Symptoms
- Itching or tingling in the mouth after lemon exposure.
- Hives, rash, or skin redness.
- Swelling of the lips, tongue, face, or throat.
- Stomach pain, nausea, vomiting, or diarrhea.
- Coughing, wheezing, chest tightness, or trouble breathing.
- Skin irritation after touching lemon peel, juice, or scented products.
Causes and risk factors
- A personal history of food allergy, eczema, asthma, or seasonal allergies.
- Reactions to other citrus fruits, such as lime, orange, or grapefruit.
- Frequent contact with lemon juice, peel, oils, or fragranced products.
- Pollen food allergy syndrome, which can cause mouth itching with certain foods.
- Family history of allergic conditions.
