Positive sweat test, do you still get a genetic test?

I'm just wondering. I was diagnosed late, at 21... was diagnosed by a sweat test, do you still get the genetic testing? My center didn't, but it seems like everyone knows their mutations.

You can get a false negative on a sweat test, but not a false positive, so I imagine your center deemed it sufficient when your test came back positive. You can inquire about them testing for which genes you have though, if you like. I asked my doc just last year to test for my second one (I knew I had one DeltaF508 from testing when I was 5, but at that time, my other gene was too rare, and had no name), and it came back within a few weeks, and now I know. I think it's an interesting piece of information, but you don't really need it in your healthcare. At least not now. It's really up to you, whether or not you want to know.

Mark had a genetic test done becuase there had alwasy been mention of a Double Delta F 508 in his medical chart, but we could never find those specific lab reports or a reference of the date the test was done. So because he was curious, he asked his doc to order the test.

I would say if you are curious, then get it done. Its likely it WILL come into play if/when you ever have children. If you have a more common mutation then it's not such a big deal when it comes to reproduction/offspring because the most common mutations show up on the newborn screening tests that most states have now. If it is a rare mutation though, you might want to know so you can screen your children. I hope that makes sense.

The reason I got tested was because my uncle wanted to know what genes I had so that he could get testing done to see if he was a carrier. The doctor wouldn't do the testing without confirming that there was history of CF in the family. The doc also wanted to know whether he would be testing my uncle for a rare or common gene as well.

I would imagine your clinic would take the initiative to do this? maybe you should ask them.. .I know my clinic does the genetic work up for all of their CF patients, but yours could be diffrent. I would want it done if they wheren't planning on it.
