Hello Cabner. Welcome to Healingwell!
Where were the two sweat tests performed at? Were they both at CF accredited centers that you know of?
I believe the Gibson/Cooke method of sweat testing is the prefered test. There are several other methods of sweat testing.
My son had the Wescor and the Gibson/Cooke, both of his were positive. I believe that his pulmo said the different tests that are performed at the same time (both arms) and or on different days (must have 2 seperate tests for diagnosis) should be in the range of no more or less than a difference of 15 in the scores/totals.
I have some links on information about the sweat tests. I will post them in a bit.
Has your doctor mentioned doing a gene mutation test (blood anyalysis)?
Good luck and hope you find your answers for your little boy.
