Does responsiveness to autologous sweat and serum in cholinergic urticaria classify its clinical subtypes?
On the basis of these findings, we propose that cholinergic urticaria should be classified into 2 distinct subtypes. The first (nonfollicular) subtype shows strong positive reactions to autologous sweat and negative reactions to autologous serum. The second (follicular) subtype shows weak reactions to autologous sweat and positive reactions to autologous serum.
