Neonatal cystic fibrosis screening - Results

Alternative Names

Cystic fibrosis screening - neonatal; Immunoreactive trypsinogen; IRT test

Normal Values:

If the test result is negative, the child likely does not have cystic fibrosis. However, if the baby has symptoms of cystic fibrosis, further testing may be needed.

What abnormal results mean:

An abnormal (positive) result suggests that your child may have CF. However, it is important to remember that a positive screening test for cystic fibrosis does not diagnose cystic fibrosis. If your child's test is positive, further tests will be done to confirm the possibility of CF.

Not all children with a positive result have CF.
