Nasal peak-flow-rate recording is useful in detecting allergic nasal reactions--a case report.

Serial nasal peak-expiratory-flow-rate recordings have been used to detect changes in nasal patency. A hospital nurse with allergy to latex showed a marked decrease in nasal flow when exposed to latex gloves in a challenge test and in her work environment. We propose using the method as a diagnostic tool for allergic rhinitis in occupational and other exposure situations in which nasal blockage is a prominent symptom.
