A member asked:
How reliable is a negative sweat chloride at ruling out cf in someone?
2 doctors weighed in across 2 answers
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.

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.
