A sweat test is used to diagnose cystic fibrosis by measuring the concentration of chloride in sweat. A positive test result indicates elevated chloride levels, suggesting the presence of cystic fibrosis, while a negative result shows normal chloride levels, indicating that cystic fibrosis is unlikely. Factors such as hydration status, age, and medications can affect the test results, leading to false negatives or positives. Therefore, it's essential to interpret the results in conjunction with clinical symptoms and other diagnostic tests.
