We had the sweat test, it came back at 33. I know this is a negative result, but is it.
I would think it would come back lower. What is a common negative result? I spoke with the nurses, who talked to the doc,at our MD's office and he feels this is not what is causing my son problems. Do I drop it? Do I do what. I dont know who to talk to.
He to me shows some signs but than he doesnt, I guess the biggest one for me is that he has not his cough for almost a year. He coughs sometimes but not much.
I am so confused.

Hi Krista!

I've readup through a few websites and they all say the same thing. Below 40mmol/l is normal, 40-60 mmol/l is borderline and above 60 are pretty much definate.

Your son falls into the normal catagory. There is only cause for extra testing when a person falls into the borderline catagory.

I'm not sure what you do from here, but another appointment with your son's doctor is the best next step. Sometimes the unknown is harder than the known. I hope that there is an answer for you soon, so you can move on to the next step to helping your son.

It must be so confusing for you, and if you still have any questions post them here, and I will try to help you.

I am in pretty much the same situation. My daughter (age 3) had a sweat chloride test with the result of 35. I was relieved when I found this out at first...but she continued to have problems and her digestive problems and respiratory problems have gotten worse. I took her to the doctor again and they are now referring her to a pulmonologist at a children's hospital for further testing. I did some more research on cystic fibrosis...I read on one forum that a lady had one child with a result of 38 (i believe 3 times) and was later genetically tested and she was diagnosed with CF. So my suggestion is to ask to be seen by a pulmonologist or cystic fibrosis specialist and get some genetic testing done!!

good luck keltay
