Class 02: 0.71 – 3.50 kU/L Moderate

Class 03: 3.51 – 17.50 kU/L High

Class 04: 17.51 – 50.00 kU/L Very High

Class 05: 50.01 – 100.00 kU/L Very High

Class 06: >100 kU/L Very High

Interpretive Data

Results with allergens scoring in Class 1 should be considered weakly positive or equivocal. Class 2 and higher should be considered positive. Although increasing class ranges (01-06) are reflective or increasing concentrations of allergen specific IgE, this may not correlate with the degree of clinical response when challenged with the specific allergen. The correlation of allergy laboratory results with clinical history is essential.
