Allergen - TUNA by EIA, Serum

Allergen – TUNA by EIA, Serum

Test Description:
The Allergen – Tuna by EIA (Enzyme Immunoassay) / specific IgE serum test measures the amount of IgE antibodies against tuna proteins in the blood. It helps identify whether an individual may have a tuna-related allergic sensitivity. Tuna-specific IgE testing is commonly used when symptoms occur after eating tuna or other seafood.

Sample Type:
• Serum (blood sample)

Purpose of the Test:
• Detect allergy to tuna
• Investigate food-related allergic reactions
• Support diagnosis of seafood allergy
• Assist in identifying the allergen causing symptoms

Common Symptoms Suggesting Tuna Allergy:
• Skin rash or hives
• Itching
• Swelling of lips, face, or throat
• Nausea or vomiting
• Abdominal discomfort
• Wheezing or breathing difficulty
• Severe reactions (anaphylaxis)

Preparation:
• No fasting usually required
• Inform the physician about current medications if applicable

Method:
• EIA / FEIA (Enzyme-based Immunoassay for specific IgE detection)

Typical Interpretation (IgE values):
• <0.10 kU/L – Negative
• 0.10–0.34 kU/L – Borderline
• 0.35–0.69 kU/L – Low positive
• 0.70–3.49 kU/L – Positive
• ≥3.50 kU/L – Increasingly stronger sensitization

Important Note:
A positive tuna-specific IgE result indicates sensitization but does not by itself confirm a clinical allergy. Results should be interpreted together with symptoms and medical history. Community discussions and clinical guidance frequently note that IgE tests can produce false positives and should not be interpreted in isolation.
