Interpretive

Reference Range:
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
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.
