What This Test Measures
The Sole Allergy IgE Blood Test measures the level of IgE antibodies to sole fish in your blood. It looks at one allergen only: sole (F337-IgE Sole).
IgE antibodies are part of the immune response involved in some food allergies. This test measures those antibodies to sole and does not measure other fish, seafood, or antibody types. A result shows whether sole-specific IgE is present. It does not confirm a food allergy on its own.
Benefits
- Measures IgE antibodies specific to sole fish.
- Uses a simple blood sample.
- Provides sole-specific information to review with your healthcare provider.
- Requires no special preparation.
- Delivers results online.
Who Is This Test For?
- You've had symptoms after eating sole or other seafood.
- You've noticed tingling around your mouth after a seafood meal.
- You've had itching, hives, or swelling after eating seafood.
- You've had abdominal discomfort, nausea, vomiting, or diarrhea after eating seafood.
- You've had congestion or wheezing after a seafood meal.
- You want sole-specific IgE information to discuss with your healthcare provider.

FAQ
1. What does the Sole Allergy IgE Blood Test measure?
It measures IgE antibodies to sole fish in your blood. IgE is the antibody type involved when the immune system treats a food protein as harmful and releases histamine. The result can help your healthcare provider evaluate sensitization to sole. It is not a confirmed diagnosis of food allergy on its own.
2. Who should consider this test, and when?
If you've had symptoms after eating seafood, this test may be relevant. Food allergy symptoms usually appear within minutes to two hours of eating, though in rare cases they can be delayed by four to six hours or longer. They may involve the skin, digestive tract, or airways. Anaphylaxis, with signs such as a rapid heart rate, a swollen throat, low blood pressure, or loss of consciousness, requires immediate medical attention.
3. Do I need to fast or prepare for this test?
No special preparation is required. You can provide your blood sample without fasting or making changes beforehand.
4. How quickly will I get my results?
Results are available in 4-6 business days. They may take longer based on weather, holiday or lab delays.
5. How should I interpret my results, and what if they are abnormal?
Your result reflects the level of sole-specific IgE in your blood. It cannot confirm or rule out a clinical food allergy by itself, and it does not predict how you would react. Interpretation depends on your result, symptoms, and medical history. If your result is abnormal, review it with a qualified healthcare provider, who can decide whether further evaluation is appropriate.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
Pre-test preparation
No special preparation is required.
Cross-Reactivity
Cross-reactivity may occur when the immune system recognizes similar proteins in different allergen sources. This test measures only IgE to sole and does not test for any of the items listed below. These examples are not exhaustive and do not mean you will react to them. They may help you and your healthcare provider consider whether related allergens are relevant, and related allergen testing may be worth discussing depending on your history and symptoms.
- Other finned fish: Fish share a protein called parvalbumin, and cross-reactivity has been reported among many species. Reactivity varies from person to person and between fish.
- Other flatfish: Fish closely related to sole, such as flounder and halibut, may share similar parvalbumin proteins.
- Shellfish: Shellfish contain different major allergens, so cross-reactivity with fish is not typical, though some people are allergic to both separately.
