Allergens included in this panel: Clam, Egg White, Codfish/Whitefish, Corn, Milk (Cow's), Peanut, Shrimp, Scallop, Soybean, Walnut, Wheat, and IgE Serum Total. Less than 0.10 kU/L: No significant level detected 0.10-0.34 kU/L: Clinical relevance undetermined 0.35-0.70 kU/L: Low 0.71-3.50 kU/L: Moderate 3.51-17.50 kU/L: High 17.51 kU/L or Greater: Very High |
| Interpretive Data: | |
|
Allergen results of 0.10-0.34 kU/L are intended for specialist use as the clinical relevance is undetermined. Although increasing ranges are reflective of increasing concentrations of allergen-specific IgE, this may not correlate with the degree of clinical response or skin testing when challenged with a specific allergen. The correlation of allergy laboratory results with clinical history and in vivo reactivity to specific allergens is essential. A negative test may not rule out clinical allergy or even anaphylaxis.
