Inhibition of gill cilial activity and of Proteus vulgaris motility as tests for aspirin idiosyncrasy.

Aspirin ingestion is likely to result in severe asthmatic attacks in patients with aspirin idiosyncrasy. There is no in vitro test for the condition. Gill cilia and Proteus vulgaris motility studies showed no differences between asthmatics with aspirin idiosyncrasy and control patients.
