Your request stays private, and you choose where the specimen is collected. Because individual sites vary, double-check the lab's own guidance on preparation, timing, and cost.
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.
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.
