CF

12/01/2008

Question:

What are the chances of cf if 1st sweat test taken on say day 1 shows abnormal, but 2 tests taken next day 1 hour apart & on different arms show borderline?

thanking you.

Answer:

While impossible to quantify, there is a chance that the correct diagnosis is CF. This is a frustrating situation, which certainly does occur. Unfortunately the tests have to be repeated until a clear answer is found or alternative testing should be pursued.
