Quick answer
The salad vegetables allergy test measures immunoglobulin E antibodies against five foods often eaten raw: spinach, tomato, cucumber, celery, and lettuce. It is ordered when someone notices itching, hives, or other symptoms after eating salads, or when a broader food allergy evaluation is underway. The test uses one blood sample and reports sensitization for each vegetable, which a healthcare provider interprets with the person's history.
What this test measures
Raw vegetables can cause allergic reactions that range from mild mouth itching to skin or breathing symptoms. Celery and tomato are among the more frequently reported triggers, while spinach, cucumber, and lettuce are also recognized allergens. Because these foods are often combined in a single dish, pinpointing the cause can be difficult without testing.
The panel uses an allergen-specific IgE immunoassay on a blood sample. Each vegetable is tested separately, and the laboratory reports an antibody level and reactivity class. Blood testing is a convenient option when a person cannot pause antihistamines for skin testing or when multiple foods need to be checked at once.
A positive result indicates sensitization, not a confirmed allergy. Some people carry antibodies without ever reacting, and cross-reactivity between related plants can complicate the picture. Clinicians combine the panel with a detailed food and symptom history, and occasionally with supervised food challenges, before advising changes to the diet.

Why people order this test
- Investigate reactions after eating salads or raw vegetables
- Evaluate suspected oral allergy syndrome triggers
- Check several plant foods in a single blood draw
- Compare sensitization across related vegetables
- Follow up on recurring hives or itching after meals
- Gather objective information before changing the diet
How to prepare
No fasting is needed for this test. A blood sample is drawn from a vein, typically at the arm. Follow the laboratory's collection instructions and share a current medication list with the ordering provider.
Understanding your results
Results are generally available within one to three business days. Each vegetable is reported with an IgE level and reactivity class. Elevated values suggest sensitization, but only a healthcare provider can determine whether the food is responsible for symptoms.

Frequently Asked Questions
What foods are included in the salad vegetables panel?
It tests for IgE antibodies to spinach, tomato, cucumber, celery, and lettuce.
Why do raw vegetables sometimes cause itching in the mouth?
Some plant proteins resemble pollen proteins, and the immune system can react to them. This is often called oral allergy syndrome and is evaluated with a clinical history and testing.
Can I eat these vegetables before the test?
Yes. Food does not need to be avoided before blood testing, though you should follow any broader instructions from the ordering provider.
Is a positive result the same as a food allergy diagnosis?
No. A positive result shows sensitization. A diagnosis depends on whether eating the food causes symptoms, which a healthcare provider assesses.
How long does it take to get results?
Results are usually reported within one to three business days after the sample is received.
