Hi there.Thank you for your question.I am Dr. SH and will be helping you out with your concerns today.
The most reassuring thing is that her screening test for CF was negative.
However the best test to do would be genetic studies to definitively rule out CF.
Salty taste of the forehead among the other symptoms that you mention are nonspecific. Even though they do happen with CF but are not specific for it and can happen even normally in some people as well.
I personally think that this may just be normal for him particularly since his screening test was normal and he has no failure to thrive which are the two most important things to consider.
However, to alleviate your anxiety, I would still do the confirmatory test for CF just to be dead sure and put your mind to ease.
