A spinach allergy test is a blood test that checks for allergic antibodies to proteins found in spinach. It is usually ordered when a person has had allergic symptoms after eating spinach or foods containing spinach, and the cause is unclear.
What it measures
- Total IgE — A general measure of allergic antibody levels in the blood.
- Spinach-specific IgE — Antibodies that bind specifically to spinach proteins.
- Other food-specific IgE — Sometimes tested together to check for related plant-food allergies.
Who it is for
This test is typically ordered by an allergist, immunologist, or primary care clinician for people who have had allergic reactions after eating spinach or who need to confirm a suspected spinach allergy.
Preparation
No fasting or special preparation is required. The blood sample can be taken at any time of day.
Results and what they mean
Results are reported as a level of spinach-specific IgE, often with a reference range. A clinician interprets the result along with your symptoms and history. This information is general and not medical advice; talk with your clinician about your results.
