CF DNA Analysis-Reference Range

Cystic Fibrosis DNA Analysis is a test to detect cystic fibrosis (CF) gene mutations and helps to diagnose CF. By using the test, doctor can determine whether you are a carrier of a CF genetic mutation.

Cystic fibrosis (CF) is an inherited disease that affects mainly the lungs, pancreas, and sweat glands. It leads to the production of thick, sticky mucus and can cause recurrent respiratory infections and impaired function of the pancreas.

The test results are as follows:

  • If a CF gene mutation panel identifies two copies of gene mutations, then the person is diagnosed with cystic fibrosis.
  • If the CF gene mutation panel reveals a single copy of a mutation or is negative and the person tested has signs and symptoms of CF, then the person is diagnosed with a more rare form of CF or is a carrier of CF.
  • If the CF gene mutation panel is positive for a single copy of a mutation and the person tested does not have signs and symptoms, then it is likely that the person is a CF carrier.
  • If the panel results are negative for mutations and the person has no signs or symptoms, then it is likely that the person does not have CF and is not a carrier.

It should be noticed that there is still a slight risk that someone who tests negative could be a carrier of a rare mutation not identified with the standard panel.
