Examination for specific allergies in relation to work: RAST, skin prick test, histamine release test. Lung function. Possibly provocation with the suspected allergen. Peak flow monitoring with at least 4 daily measurements during periods of work and leisure, for example. a week of each. Temporarily stopping the medication considered in peak flow monitoring, testing for bronchial hyperreactivity,
