Correct Answer: Cystic fibrosis
Description: The diagnosis of CF rests on the combination of clinical criteria and abnormal CFTR function as documented by sweat tests, nasal PD measurements, and CFTR mutation analysis. Elevated sweat Cl- values are nearly pathognomonic for CF. The sweat concentration values for Cl- (and Na+) vary with age, but, typically, a Cl- concentration of >70 meq/L in adults discriminates between CF and other lung diseases. Ref: Boucher R.C. (2012).
