Sample

Blood draw or sample collection at a local center

A sole-specific IgE blood test measures antibodies the immune system may produce against proteins in sole, a commonly eaten flatfish. It is a screening tool for suspected fish allergy rather than a diagnosis on its own. A clinician may order it after a reaction to sole or other fish, as part of a broader seafood panel, or when symptoms suggest sensitivity to sole and related fish species.

• Sole-specific IgE Antibodies produced in response to sole proteins, used to assess sensitization.

• Hives, itching, or swelling after eating sole
• Throat tightness, wheezing, or breathing symptoms after fish exposure
• Digestive symptoms following sole or fish meals
• Testing as part of a broader fish or seafood allergy panel
• A history of reactions to other flatfish or fish species

• No fasting is required for most IgE allergy tests
• Tell the collector about antihistamines or other medications you take
• Drink water before the blood draw
• No special diet is needed beforehand

An elevated sole-specific IgE level may indicate sensitization to sole proteins and can be associated with allergic reactions. A positive result alone does not confirm a clinical allergy, and a low level does not fully exclude one. Some fish proteins cross-react between species, so a healthcare provider should interpret the result with your history and symptoms.
