The vast majority of those with elevated IRT levels only (not all states include any genetic testing as part of newborn screening) are false positives.

<br />It would be a lower percentage of those that have both elevated IRT as well as one mutation found that do not have CF, but odds are still in your favor that your child is a carrier.

<br />I don't know if Emily tasted salty as an infant. She does taste very salty now. My other children do not. Her sweat test result was twice as high as one of my sons and 3x as high as the other.
