Question Sweat Test vs. Genetic Testing


Just wondering, from you personal experience, which test is more accurate?
The sweat test or blood test (Genetic Testing)?

Re: Sweat Test vs. Genetic Testing

In my experience with my children the genetic testing is more reliable. My children have been going through CF testing for three years. Both kids came back borderline on two sweat tests each. Doctor had us have genetic testing done on both. Both kids testing showed they are carriers. Until just three months ago my sons sweat tests still put him in the borderline range, now he is in normal and considered to just be a carrier, thought the CF doctor will continue to follow him a few more years. My daughter is a carrier, but her sweat tests show her to still be at the high end of border line so they are saying she is carrier with symptoms until they can get a more definite answer. Genetic testing can test all the known mutations (new mutations are found as they continue research). Sweat test is the first step though. Good luck.
