Comparison of BAT performed with vs without IgE in healthy (non-atopic) persons and atopic patients. The atopic patients are divided into those atopic to the allergen of interest per SPT result (middle) and those allergic to a different allergen(s) (right). Significance of the difference between groups stained with and without IgE is given in the upper section of each plot. BAT results are displayed as corrected percentage of activated (CD63+) basophils (saline control percentage subtracted).
