Geometric mean (95% confidence interval) of allergen concentrations in reservoir dust^*

	Der p 1 (μg/g)	Fel d 1 (μg/g)	Bla g 1 (Units/g)
Bedding	6.54 (4.89–8.19)	5.42 (2.70–8.15)	0.75 (0.00–2.00)
Bedroom floor	7.71 (6.27–9.16)	4.69 (2.51–6.86)	0.32 (0.00–1.69)
Living room floor	5.31 (3.71–6.91)	6.54 (4.52–8.56)	0.41 (0.00–1.90)

^*In the current study, Indoor Biotechnologies individual allergen standards were used and not the Universal Allergen Standard. A correction factor may be required when comparing allergen concentrations with studies that have chosen to adopt the Universal Allergen Standard (Filep et al., 2012).
