Other diagnostic<unk>  in patients with cystic fibrosis include sweat chloride test (measures the chloride content of the sweat) and nasal potential differences (performed by running different solutions through the nose) which used to detect changes in CFTR function. A sweat chloride value of more than 59 mmol/L is diagnostic for cystic fibrosis and less than 30 mmol/L indicates that cystic fibrosis is unlikely. Also Pulmonary function test (PFT) is important in monitoring lung function in patients with cystic fibrosis. However, it is only an indirect measure of lung structure and is insensitive to local or early damage.
