Spinach Antibody Test in Arizona

What this test measures

Vegetable allergies are less common than allergies to nuts, shellfish, or dairy, but they do occur. Spinach contains proteins that the immune system can mistakenly target in sensitive people. Reactions may be mild, such as oral itching or hives, or more involved. Because spinach is often eaten with other ingredients, pinpointing it as the trigger can be difficult without testing or a careful food history.

The test measures spinach-specific IgE in a serum sample and reports a level or reactivity class. It can be ordered on its own or as part of a vegetable or food panel. Results show whether the immune system has produced antibodies against spinach proteins and are interpreted with the timing of symptoms after eating.

A positive result indicates sensitization and does not guarantee that eating spinach will cause a reaction. Some people with positive tests tolerate the vegetable. A qualified healthcare provider uses the test result together with the clinical history to decide whether spinach is likely involved and to discuss next steps.
