2. What is the interpretation of specific IgE testing?
Specific IgE levels are expressed semiquantitatively in RAST classes as well as quantitatively in kU/ml. The following table shows the relationship between these two parameters.

Specific IgE, kU/ml	RAST class	Clinical expression of IgE level
< 0,35 IU/ml	RAST class 0	negative
0,35–0,70 IU/ml	RAST class 1	low
0,70–3,50 IU/ml	RAST class 2	mild
3,50–17,5 IU/ml	RAST class 3	moderate
17,5–50,0 IU/ml	RAST class 4	high
50,0–100 IU/ml	RAST class 5	very high
> 100 IU/ml	RAST class 6	very high
