Overall | 215 | 88.8 | <.001 | 93.0 | <.001 | 93.5 | <.001 | 94.9 | .001 |

Sensitivity of the four molecular assays tested increased with sIgE levels to D.p. extract. In the case of sIgE levels ≥ 1.0 kU/L, ALEX2 and in the case of sIgE levels ≥ 3.5 kU/L, all molecular assays performed statistically equal to extract‐based diagnosis. All P‐values listed are direct comparisons to extract‐based singleplex diagnosis using ImmunoCAP.
