Sweat Test after CFTR Test Negative

I am in my mid-forties and have problems with abdominal pain since I was a teenager. I have just been diagnosed with chronic pancreatitis. I had a genetic CFTR sequencing done with deletions/duplications via aCGH this past summer. The only variations that showed up in the tests were the following common variants. v470m heterozygous p1290p heterozygous t854t heterozygous g1463g heterozygous I am going to meet with the gastroenterologist next week and I was wondering if it is appropriate to ask for a chloride sweat test before ruling out cystic fibrosis as a cause. They have ruled out other causes such as alcohol, gallbladder (hida scan had an ejection fraction of 80%), autoimmune, hypercalcemia, high triglycerides, pancreas divisum, etc. Sincerely, Melissa
