How is Cystic Fibrosis diagnosed?

The doctor will study your family's medical history and they will also do a series of physical exams. They will preform sweat tests, blood tests, chest and sinus X-rays, and lung function tests.

• Sweat test(s) measures the amount of salt in your blood
• Blood test(s) search for symptoms that indicate CF
• Chest X-Ray(s) are used to look for any inflammation in the lungs
• Lung function test(s) measure the amount of air you lungs can take in, how quickly you breathe, and how well your lungs add oxygen and remove carbon dioxide from your lungs
