Overview
Other diagnostic studies in patients with cystic fibrosis include sweat chloride test and nasal potential differences.
Other Diagnostic Studies
- Sweat chloride test: This test is an indicator of CFTR function and measures the chloride content of the sweat in the patients with cystic fibrosis.
- A sweat chloride value of more than 60 mmol/L is diagnostic for cystic fibrosis.
- Nasal Potential Difference (NPD): In patients with cystic fibrosis NPD is performed by running different solutions through the nose. Voltage measurements from these solutions are used to detect changes in CFTR function.
