What this test is

This test measures immunoglobulin E (IgE) antibodies that your immune system may produce in response to lettuce proteins. It is used to evaluate whether a lettuce allergy is possible when symptoms occur after exposure. The test does not diagnose an allergy by itself; it is interpreted alongside your history and other findings.

What it measures

  • Lettuce-specific IgE antibody — reflects immune sensitivity to lettuce proteins
  • Total IgE (if included) — shows the overall level of allergic antibodies in the blood
  • Other food-specific IgE antibodies (if a panel is ordered) — helps identify reactions to related or additional foods

What the test involves

A healthcare professional collects a small blood sample, usually from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test if you have had symptoms such as hives, itching, swelling, stomach upset, or breathing trouble after eating lettuce or foods that contain it. It can also be part of a broader evaluation for food-related allergic reactions.

Preparation

No special preparation is usually required, but follow the collection lab's instructions. If you take medications, ask the lab or your clinician whether any need to be adjusted before the draw.

How results are reported

Results are reported as a numeric level or a qualitative category, depending on the laboratory's method. Reference ranges and cutoffs vary by laboratory, so your result must be interpreted using the range provided by the testing lab.

Before you go

  • Whether any medications you take could affect the test
  • How and when you will receive your results
  • Whether a follow-up visit is needed to discuss the findings
