Allergen, Food, Barley
Also known as: BARLEY
Use
This test measures allergen-specific IgE levels for barley using a quantitative ImmunoCAP Fluorescent Enzyme Immunoassay. It is utilized to assess the probability of IgE-mediated clinical reactions to barley and assists in correlating allergy laboratory results with clinical history and in vivo reactivity to specific allergens.
Special Instructions
Ensure the separation of serum from cells ASAP or within 2 hours of collection. For detailed collection instructions, refer to 'Allergen Specimen Collection Instructions' at www.aruplab.com/testing/resources/specimen.
Limitations
Allergen results of 0.10-0.34 kU/L are intended for specialist use as the clinical relevance is undetermined. Increasing IgE concentrations may not correlate with the degree of clinical response or skin testing results. A negative test may not rule out clinical allergy or anaphylaxis. The correlation of allergy laboratory results with clinical history and in vivo reactivity to specific allergens is essential.
