In brief: See below

The sweat chloride test is the gold standard for diagnosing cf.
If an adequate amount of sweat was obtained, and the test was negative, then CF is unlikely.

In brief: Repeat if suspected

The sweat chloride test is reliable in ruling out CF, but if there are symptoms, I would suggest a repeat sweat chloride test and genetic testing.
