Allergen, Food, Banana
Also known as: BANANA
Use
This test is used to measure the level of allergen-specific IgE antibodies against bananas. The results indicate the presence of these antibodies and can help diagnose potential IgE-mediated allergic reactions to bananas. It is essential to correlate allergy laboratory results with clinical history and any in vivo reactivity to specific allergens. Despite increasing antibody levels, they may not directly correlate with the clinical response or skin testing results when challenged with the allergen.
Special Instructions
Multiple patient encounters should be avoided to prevent variability in test results. After blood collection, serum should be separated from cells as soon as possible or within 2 hours to ensure the accuracy of the test. Follow the "Allergen Specimen Collection Instructions" for multiple allergen orders.
Limitations
The concentrations of allergen-specific IgE detected in this test may not always correlate with the degree of clinical allergic reaction. A negative result does not rule out a clinical allergy or even anaphylaxis. Interpretation of results should account for the clinical history and in vivo reactivity to specific allergens. Allergen results within a range of 0.10-0.34 kU/L are for specialist use as clinical relevance is undetermined.
