Diagnostic Tests

Screening for cystic fibrosis

All babies born in New Hampshire are now required to be screened for cystic fibrosis. Read more about newborn cystic fibrosis screening.

Diagnosing cystic fibrosis

If the newborn cystic fibrosis screening result is positive, a child must have a sweat test. People with cystic fibrosis (CF) have an abnormal amount of salt in their sweat. The sweat test measures salt in the sweat, and helps a doctor diagnose cystic fibrosis.

Monitoring cystic fibrosis

During a CF patient's clinic visit, a doctor may choose to perform one or more common CF tests. These tests measure many things, including how well a patient's respiratory system is functioning. After getting the results of these tests, the doctor may prescribe a medication to fight an infection, or physical therapy to help clear mucus from the lungs.
