Quizplus · Accepted Answer

A sweat test is the most common and accurate test for diagnosing cystic fibrosis. It measures the amount of salt in the sweat, as people with cystic fibrosis lose more salt in their sweat than those without the condition. This test helps to confirm a diagnosis of cystic fibrosis and also helps to determine the severity of the condition.
