Clinical Information:
Cyctic fibrosis (CF) it the common life-threatening genetic disease within the white population. It id an autosomal recessive disorder characterized by viscous secretions that affect the exocrine glands, primarily in the lung and pancreas. Patient with CF have an increased concentration of sodium, chloride and potassium in thier sweat. The criteria for diagnosis of CF include the presence of one or more characteristic phenotypic features, or a history of CF in a sibling, or a positive new born screening test result; and an increased sewat chloride concentration by pilocarpine iontophoresis on two or more occasions, or identification of two CF-causing mutations or demonstration of abnormal nasal epithelial ion transport.
 
Reference Value:
0 -50 mmol/L
