Question for anyone with sweat test in the 30's.

My daughter's fecal fat test just came back positive so she does have fat malabsorption but no conclusive diagnosis of CF yet. Sweat test came back 34 and then the next one dipped all the way down to 18. Do you know if sweat tests are supposed to vary that much? Maybe the second one was a technical error? Doctor says some sweat tests in the 30s still can be CF. Esp. with a positive fecal fat situation. What do you think? Are there any other common causes of fat malabsorption in children besides CF? We might pursue genetic testing such as Ambry.
God bless all CF moms!
