We just took our little two week old in for a sweat test. He is a carrier of the Df508, and were sent to get a sweat test on him. The results were a 32 on the sweat test, which has mom and me a little freaked out. We have no history of CF in our family, and this just kind of blind sided us. Could it be possible he was just to little for the sweat test? 32 is right at that border range. We just cant get it out of our heads. Any help will or experience in similar circumstances would be very helpful! Thanks.
