Allergen, Individual-Food Pistachio F203

The Allergen, Individual-Food Pistachio F203 is a laboratory blood test that measures pistachio-specific IgE antibodies to detect sensitisation to pistachio (Pistacia vera) proteins. The sample is collected at home by a certified phlebotomist and analysed in a UAE‑accredited laboratory to provide objective evidence that complements clinical history and symptoms.

This test is useful for individuals who have experienced suspected allergic reactions after eating pistachio, those with a history of nut allergies, or parents considering controlled introduction of pistachio to children. Results help clinicians and patients make informed dietary decisions and emergency-preparedness plans in Dubai; however, a positive result indicates sensitisation and does not always predict clinical severity—oral food challenge remains the diagnostic gold standard when needed.

• Pistachio-specific IgE (sIgE)
• Specific IgE concentration (kU/L)
• Result interpretation category (Negative/Low/Moderate/High)

• After an immediate allergic reaction (hives, swelling, breathing difficulty) following pistachio ingestion
• When unexplained gastrointestinal, skin or respiratory symptoms occur after eating nuts
• Before introducing pistachio to infants/children with family history of nut allergy or eczema
• To confirm sensitisation in individuals with known tree‑nut allergy for diet planning
• When planning supervised oral food challenge or specialist referral

• Convenient at‑home blood collection by trained phlebotomists
• Analysis in a UAE‑accredited laboratory with secure reporting
• Fast turnaround to support timely dietary and emergency decisions
• Objective measurement to reduce unnecessary broad nut avoidance
• Useful documentation for school, childcare or workplace allergy management

• At‑home venous blood collection by a certified phlebotomist (pediatric collection available)
• No fasting or special dietary preparation required
• Provide a list of current medications and relevant allergy history at time of collection
• Inform the phlebotomy team of any recent severe allergic reactions or use of immunosuppressive therapy
