My 6 year old had a sweat test done and it read 41 and today 2-18-2009 she had a sweat test done and the result was 60. I have had a nurse tell me that is positive and I have had someone tell me it is high borderline.
Can anyone tell me is 60 positive or high end borderline?

I had a 8 year old who tested 42 on a sweat test.

Thanks for information

Hi there Lori

<40 is negative
40-60 is a borderline/grey area
>60 is positive.

I think you can have a false negative, but not a false positive. However 60 is sort of rocking on the edge still. I think your children may need genetic testing to get definate results.

Hope this helps

I have had my son at Children's Hospital in St. Louis for testing.  He has a sweat test at 55 and the 2nd one was 62.  They told me that the results were both borderline.  Their levels are
  <40 Negative
  >80 Positive
   41-79 Borderline
We are now waiting on the genetic tests to come back.
