Re: Daughter having sweat test on monday - help
Both parents have to be carriers to give a child CF; however, there are over 1500 cf mutations and if they only tested for 97, there is a chance that your child could very well have CF. The sweat test CAN be a good tool for inexpensive and early detection of CF IF it is properly adminstrated. But it is no longer considered the gold standard. DS' was a normal 32; however blood tests showed that he had two copies of a cf gene, meaning he had CF.
The test is fairly simple. They put little sweatbands on each arm (or leg) and wait several minutes and they remove them. Then you wait for the results to come back from the lab. It should only take a short period of time (minutes/hours), but usually the doctor wants to get the results and report them back to you.
Blood tests can take a week to several weeks depending upon whether they do ambry amplified or quest or just a basic test.
