How can i know if i have cystic fibrosis?

Need to be tested: You can only be diagnosed with cystic fibrosis (CF) by testing. A sweat chloride testing must be done, which is considered the gold standard test for cf.

Get tested: Testing for cystic fibrosis starts with a sweat test. If that is abnormal, genetic testing in the blood is used to confirm the diagnosis by finding the specific genetic mutations. In general, people with CF have recurrent pulmonary infections and abdominal discomfort/diarrhea due to fat malabsorption.
