The blood test is a screening test, meaning it cannot identify a birth defect in the baby, it only indicates that the risk is higher and further testing is needed. Doctors may also recommend genetic tests for specific defects on the gene responsible for cystic fibrosis. For an infant suspected of having cystic fibrosis, the test can be performed as early as 48 hours after birth, though any test conducted during a baby's first month might need to be repeated because newborns may not produce enough sweat to ensure reliable results.
