*

ELISA dose response curves using the Universal Allergen Standard (Lot # 31012) or individual ELISA standards were compared in two separate assays (i) and (ii).

**

Dust extracts (n=13 to 18) were analyzed by ELISA using either UAS or individual ELISA standard. Values represent the mean correction factor of all the dust samples tested.
