Table 1. Correlation between total IgE (kU/L) and test results.

	Double sensitization	Mono sensitization	Double negative	p
BAT	54.3 (24.5; 217.3)	64.7 (36.9; 151.0)	58.9 (22.7; 112.0)	0.463
ADVIA	117.0 (50.9; 397.6)	51.7 (30.3; 123.4)	35.9 (10.4; 142.4)	0.008
IDT	88.7 (45.2; 252.0)	53.9 (29.4; 103.5)	35.3 (8.7; 69.0)	0.014
CAP	90.8 (48.9; 230.0)	43.3 (29.1; 64.2)	28.0 (10.6; 66.0)	0.000
Immulite	87.2 (42.6; 246.0)	51.5 (19.6; 87.5)	8.0 (2.7; 95.6)	0.006

In all tests except in the BAT, double sensitized patients showed higher levels of total IgE (tIgE) compared to mono sensitized patients. Conversely, double negative patients had lower tIgE levels compared to mono- and double sensitized patients.
