Allergens, Inhalants/Foods, Western Allergy Profile
Also known as: WEST PAN
Use
The Western Allergy Profile is used to determine specific IgE levels to various common inhalant and food allergens. The results provide valuable information for diagnosing allergic conditions and assisting in allergy management by identifying sensitivities to specific allergens. Results are measured using the ImmunoCAP Fluorescent Enzyme Immunoassay, which offers quantitative insights into allergen-specific IgE concentrations. The profile includes a wide range of allergens including molds, animals, foods, weeds, and trees, allowing for comprehensive allergy assessment.
Special Instructions
Multiple patient encounters should be avoided to ensure the accuracy of the test results. Serum should be separated from cells as soon as possible and transferred to an ARUP Standard Transport Tube. Minimum volume required is 1.16 mL. Use a serum separator tube to collect the sample.
Limitations
Results indicating allergen-specific IgE levels of 0.10-0.34 kU/L are considered clinically undetermined, and further specialist evaluation may be needed. Despite rising IgE concentrations, there may not be a direct correlation with the degree of clinical reaction or skin test results. Interpretation needs to be in conjunction with clinical history and other diagnostic findings to ensure comprehensive assessment.
