In brief: Cystic fibrosis
The sweat test is usually done when the infant is a month old, to ensure the sample is large enough to be analyzed.
The sweat test can determine if the infant carries the cystic fibrosis gene or has the condition. Testing should be done at a center specializing in cystic fibrosis.

In brief: If symptoms rep test
If the sample collection and test is performed correctly it is very reliable.
If a patient is experiencing symptoms that raise a suspicion for cf, the test should be repeated and a genotype analysis ordered.
