A lettuce allergy test is a blood test that checks for allergic antibodies to lettuce. It is ordered when someone has allergic symptoms after eating lettuce or lettuce-containing foods, such as itching, hives, or digestive upset.
What it measures
- Lettuce-specific IgE — Measures antibodies that target lettuce proteins.
- Total IgE — Shows the overall level of allergic antibodies in your blood.
- Other food-specific IgE — May be checked for foods often linked to lettuce allergy, like mugwort or birch pollen.
Who it is for
This test is usually ordered by an allergist, immunologist, or primary care clinician when a lettuce allergy is suspected.
Preparation
No fasting or special preparation is needed. Tell your clinician about all medicines you take, especially antihistamines, as they may affect results.
Results and what they mean
Results are reported as a level or class for lettuce-specific IgE, along with a reference range. A clinician interprets these results with your symptoms and history; a positive test alone does not confirm an allergy. This is general information, not medical advice.

How long does it take to get results?
Results are typically available in 1 to 3 business days.
Is this test covered by insurance?
Coverage varies by plan. Check with your insurance provider before testing.
