Sensitivity and Specificity of Different Diagnostic Methods in 2 Studies With Patients With AE

Test	Sensitivity*	Specificity*
Single-center study, n = 79 (allergen, grass pollen)
Skin prick	100	33
RAST	92	33
APT	75	84
APT multicenter study, n = 253 (3 allergens)
Skin prick	69-82	44-53
RAST	65-94	42-64
APT	42-56	69-92

Better results are obtained with a seasonal allergen. Data from Ref. [61] and Ref. [57]

*Referring to predictive history of eczema exacerbations in pollen season or in direct contact with allergen, excluding questionable cases, depending on allergen.
