Relationships among ragweed skin tests and both allergen specific and nonspecific nasal provocation.
Twenty-six patients with ragweed-induced allergic rhinitis were evaluated prior to the onset of seasonal symptoms. Ragweed skin tests and nasal challenges were performed 2 weeks after histamine nasal provocation. A correlation between ragweed skin tests and nasal challenges was detected (r = .4867, P much less than .01). Histamine challenges did not correlate with either of the other variables. A properly performed skin test predicts nasal reactivity to the same allergen. A clinical role for nonspecific nasal provocation could not be determined.
