IgE, IgG1, and IgG4 Reactivity to Dermatophagoides pteronyssinus Glycosylated Extract in Allergic Patients

Figure 3

Correlation between levels of specific IgE (a, b), IgG1 (c, d), and IgG4 (e, f) to the D. pteronyssinus (Dpt) crude extract and ConA-unbound or ConA-bound fractions, expressed in ELISA index (EI) in sera from 95 patients with positive SPT to D. pteronyssinus (DP+ group; full squares, half left) and 92 nonallergic subjects (NA group; empty squares; half right). Correlation coefficient (r) was calculated using the Spearman correlation test.

(a) IgE

(b) IgE
