Allergen, Food, Sardine IgE
Also known as: SARDIN IGE
Use
The Allergen, Food, Sardine IgE test is used to measure the levels of IgE-antibody specific to sardine allergens in the blood. This test helps in the diagnosis of allergies to sardines, which can manifest in symptoms such as hives, difficulty breathing, or gastrointestinal issues after consuming sardine-containing foods. It assists clinicians in correlating results with clinical history and physical examination findings.
Special Instructions
Not provided.
Limitations
The clinical relevance of IgE levels between 0.10-0.34 kU/L is undetermined and should be interpreted by specialists. The test results may not correlate with clinical response severity or skin testing outcomes. A negative result does not rule out an allergy or anaphylactic potential. Correlating test results with clinical history and in vivo allergen reactivity is crucial for accurate diagnosis.
