ALLERGENS FOOD, TUNA, IgE F40

ALLERGENS FOOD, TUNA, IgE F40 is an at‑home allergy test that detects tuna‑specific IgE antibodies in a blood sample to assess sensitization to tuna (Thunnus spp.). The sample is collected at home by a trained phlebotomist or via a validated finger‑prick kit and analysed in UAE‑certified laboratories using standardized immunoassays to provide quantitative sIgE results.

This test is useful for individuals who have experienced allergic symptoms after eating tuna, for families introducing fish to at‑risk infants, or for anyone seeking objective information to guide dietary choices and avoidance strategies. Results are reported in standard units (kU/L) with sensitization classes to help clinicians evaluate the likelihood of clinical reactivity; however, results should always be interpreted alongside clinical history and, if needed, supervised oral food challenge by an allergist.

Turnaround times in Dubai/UAE typically range from 24–72 hours after sample receipt by the lab. Note that a positive sIgE indicates sensitization but does not guarantee symptomatic allergy; conversely, low or negative sIgE reduces the likelihood of IgE‑mediated reaction but does not completely exclude non‑IgE mechanisms. Always review results with a qualified healthcare professional before making major dietary changes or treatment decisions.

• Tuna (Thunnus spp.) specific IgE
• sIgE concentration (kU/L)
• Sensitization class (0–6)

• After immediate allergic reaction (hives, swelling, wheeze) following tuna consumption
• Recurrent unexplained oral or gastrointestinal symptoms after eating fish
• Before introducing tuna to infants or young children with family history of fish allergy
• When assessing risk prior to travel or dining out in the UAE
• To monitor sensitization status when guided by an allergist

• Convenient at‑home sample collection with UAE‑certified laboratory analysis
• Objective detection and quantification of tuna‑specific IgE
• Rapid results to support timely dietary and safety decisions
• Helps clinicians stratify allergy risk and plan further testing or management
• Reduces uncertainty about tuna exposure for patients and caregivers

• At‑home blood collection by trained phlebotomist or validated finger‑prick kit
• No fasting required
• Inform the provider about current immunotherapy, biologic treatments (e.g., omalizumab), or recent severe reactions
• Valid Emirates ID and parental consent required for minors under 18
