The sweat test is the gold standard diagnostic test for cystic fibrosis. It measures the amount of chloride in sweat, which is typically elevated in individuals with cystic fibrosis. The spirometry and pulmonary angiography may be used to evaluate lung function and blood flow, respectively, but they are not specific to cystic fibrosis. Sputum cytology may be used to evaluate for lung cancer, but is not specific for cystic fibrosis.
