| Use: | Allergen results of 0.10-0.34 kU/L are intended for specialist use as the clinical relevance is determined. 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 a clinical allergy or even anaphylaxis. |
