title: New tests for cystic fibrosis.
abstract: Most patients presenting with symptoms and signs of CF are still diagnosed on the basis of a sweat test. CFTR mutation analysis is useful in confirming the diagnosis, screening family members, newborn screening programmes and in those with borderline or normal sweat tests with a high index of suspicion. Nasal PD can also be helpful in the latter group, although there are a number of caveats to its use and interpretation.
