Aeroallergens sensitization pattern in atopic patients in Qatar: A retrospective study.

Insects (house dust mites and cockroaches) and animal protein (cat hair) were the most prevalent positive aeroallergen by skin tests. However, weed, tree pollens (Russian thistle, Rough pigweed, Mesquite tree), and grass pollens (Bermuda and seven grass mix) were also positive for a minority of patients. 62% of patients were polysensitized to aeroallergens.
