Cystic fibrosis is usually diagnosed by a sweat test which measures the amount of salt in a person’s sweat. People with cystic fibrosis have higher levels of salt in their sweat. A fecal fat test may be used to confirm the diagnosis. Genetic mapping may be used to identify mutations but cannot definitively diagnose cystic fibrosis. Urinalysis is not used to diagnose cystic fibrosis. Cystic fibrosis is typically diagnosed through a sweat test, which measures the concentration of salt in sweat. People with cystic fibrosis have abnormally high levels of salt in their sweat. This test is usually done in conjunction with genetic testing to confirm the diagnosis. Fecal fat test, urinalysis, and genetic mapping may be used for other purposes in the diagnosis or management of cystic fibrosis, but they are not typically used as the primary diagnostic tool.
