Class 00: < 0.35 kU/L Absent or undetectable
Class 01: 0.35-0.70 kU/L Low
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: > 100.00 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 of 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.  A negative test may not rule out clinical allergy.
