Sweat Test Numbers

[DietRootBeer]

Hello,



I am curious for those of you with CF that passed the sweat test what were your numbers? I think it went as follows: 0-40 normal, 40-60 grey area, 60 + CF.

I am asking this because my husband and I are both carriers. My mutation is known but they have never been able to trace my husband's mutation with all the testing that is available today.

Since my younger son cannot be confirmed with a blood test he has had 2 sweat tests: The first test he scored 9 and the second he scored 8.

He has been to the clinic before and they said they are confident he is CF free...but I always worry.

Thanks!

Hey! You've got two of these going --

Here is a copy of what I posted on the other topic

my kids sweat tests are 38 and 41 (read my first entry on my blog for more details) but yes, they are near the top of the normal/borderline numbers -- your child's numbers of 8 and 9 are quite low and more clearly in the normal range.

It's a good question -- I would feel the same way. I'm guessing that most people who say they have a negative or normal sweat test but genetically know they have two mutations are probably at least over 20 on the sweat test (somebody correct me if you are the exception here) But I think if a clinic has checked him out and said they really don't think he has CF, you have done all you can do for now (assuming he isn't having any symptoms) -- different story if he is presenting with some cf type issues then I would say keep pushing -- but if not, I'd say you are most likely in the clear.

I'm confused: If they can't identify your spouse's mutation and have not identified your child as positively having CF, what's the basis for saying he's a carrier?

My son had two completed. They wanted the 2nd one done to confirm the diagnosis. First one was 109, 2nd 113. They really didn't have any issues with deciding whether positive or negative with the high numbers. However, I did request the blood work to be done as well to know what mutations he had. Delta 508 (husband), deletion exon 2 & 3 (mine).

Thanks Alyssa<img src="i/expressions/face-icon-small-smile.gif" border="0"> I do not know what happened...I must have hit it twice!

Anonymous: My son has my gene but we are not sure if he has my husband's gene because his is unknown ( but we are positive he has a mutation because he has a son w/cf) ...understand?

Thanks for the replies....
