How do they test for cystic fibrosis in adults?
To diagnose cystic fibrosis in adults, we perform a comprehensive exam and collect a thorough history. Diagnosis is most often made using a sweat test, which measures the amount of salt in your sweat using a chemical on the skin that causes you to sweat, and then collecting the sweat for analysis.

How do you monitor cystic fibrosis?
Pulmonary function tests, which includes checking oxygen levels in your blood and spirometry, which is the most important and widely used tool to assess lung function in cystic fibrosis. Regular spirometry is used to monitor lung function in people age 6 and older and may be done in children as young as age 3.
Can a blood test detect cystic fibrosis?
Do I need to request it? Every state’s newborn screening program includes a test for cystic fibrosis, so you will not need to request it. The method used may vary, with some states performing a blood test to determine the level of immunoreactive trypsinogen (IRT) and others screening for CF with gene mutation testing.

These cells make up the sweat glands in the skin and also line passageways inside the lungs, liver, pancreas, and digestive and reproductive systems.
