What it measures
- Potato-specific IgE — Measures antibodies that may indicate an allergy to potato proteins.
- Total IgE — Sometimes included to show the overall level of allergic antibodies in the blood.
- Cross-reactive carbohydrate determinants (CCDs) — Can cause false-positive results; may be checked to help interpret the potato IgE level.
Preparation

Results and what they mean
Results are reported as a numerical level of potato-specific IgE, often with a reference range. A clinician interprets the number along with your symptoms and history; a positive result alone does not always mean you have a potato allergy. This is general information, not medical advice.
