To assess the prevalence of skin test sensitivity among asthmatic patients in Malaysia, skin prick tests for allergy in 134 adult asthmatic patients and 120 control subjects were done. 90% of asthmatic patients had positive skin test to at least one allergens as compared to 78% of the controls. House dust mite was the most frequent allergen to which the subjects had positive reactions. Sixty-four percent of the asthmatic patients had associated rhinitis. There was no significant difference in the skin test sensitivity between asthmatic patients with associated rhinitis and those without.
