PCBAT with cat allergen extracts on cat sensitized but clinical reactivity not validated subjects. PCBAT using cat allergen extracts from ALK (dilution factor 1:250; 1:1250; 1:6250; 1:31,250; 1:156,250 and 1:781,250) were performed on (A) 18 cat sensitized but clinical reactivity not validated subjects; (B) the relationship between the PCBAT AUC from the sensitized groups and the corresponding sIgE level were shown in scatter plot. (C) PCBAT using cat allergen extracts were also performed on six atopic but non‐cat sensitized subjects and (D) 4 subjects who are sensitized to cat allergen but under omalizumab treatment, spearman test and R square was calculated and p < .05 were considered significant.
