Table II. Allergens that were most frequently detectable by chip technology in the patient group with mastocytosis and in individuals of the control cohort.

Allergen	Mastocytosis (n = 42)	Nonadvanced mastocytosis (n = 34)	Advanced mastocytosis (n = 8)	Controls (n = 42)
Ves v 5	16.7	17.6	12.5	16.7
Bet v 1	11.9	14.7	0	9.5
Aln g 1	9.5	11.8	0	7.1
Cor a 1.0401	7.1	8.8	0	7.1
Phl p 1	9.5	11.8	0	14.3
Phl p 5	7.1	8.8	0	14.3
Ole e 1	7.1	8.8	0	7.1

Values represent % of patients. Sera obtained from 42 patients with mastocytosis and 42 controls without mastocytosis were analyzed for specific IgE by the chip. Results for the chip-positive cases are shown as a percentage of all patients in each group. Allergen designation: Aln g 1, pathogenesis-related protein (PR-10) from alder; Bet v 1, PR-10, pollen from birch; Cor a 1.0401, PR-10 from hazelnut; Ole e 1, common olive group 1 (olive); Phl p 1, beta-expansin, pollen from timothy grass; Phl p 5, pollen from timothy grass; Ves v 5, antigen 5, venom from yellow jacket.
