Allergen, Food, Quinoa IgE
Also known as: QUINOA IGE
Use
This test is utilized to quantify the allergen-specific IgE antibodies to quinoa in patient serum. High levels of allergen-specific IgE may indicate sensitization to quinoa, but correlation with clinical history and in vivo reactions to quinoa is essential for diagnosis. The test is particularly useful for specialists seeking insight into potential allergies, but IgE concentrations might not always correlate with clinical symptoms or skin test results.
Special Instructions
The test performance characteristics were determined by ARUP Laboratories, but it has not been cleared by the US FDA. It's essential to correlate laboratory results with clinical history and in vivo reactivity. Specimens should be separated from cells within 2 hours of collection.
Limitations
Despite measurable concentrations of quinoa-specific IgE, there may not be a direct correlation with the degree of clinical reaction upon exposure. A negative result does not rule out the possibility of clinical allergy or even anaphylaxis. The reliability of this test in predicting allergic rhinitis, asthma, or other IgE-mediated reactions may vary according to individual patient responses.
