Interpretive

Reference Range:
Less than 0.10 kU(a)/L None Detected
0.10-0.69 kU(a)/L Low
0.70-3.49 kU(a)/L Moderate
3.50-17.50 kU(a)/L High
Greater than 17.51 kU(a)/L Very High
   
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.
