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.

Requesting the Lettuce Allergy Test in Illinois

Order online, choose a certified collection site in Illinois, and review results through a secure portal. No referral is required, and orders are processed confidentially. Access across Midwest is steady, so confirming a site ahead of time is worthwhile.

Frequently asked questions

Do I need to avoid lettuce before the test?

No. The test measures antibodies in your blood, so you do not need to change your diet beforehand.

Can this test tell me if I will have a severe reaction?

No. It shows sensitization, but the severity of an allergic reaction cannot be predicted from the test alone.

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.
