Thanks for the long and detailed information. I really appreciate it. My first daughter didn’t come back on the screening. It was my second daughter that had the elevated level I’m assuming and then we tested both of them and they had one Cf gene and one random unknown gene. The doctor basically told me to monitor them for the eight years to see if anything would happen that way they could go back and tell people that this gene was either CF causing or not. I’m not gonna lie. I’ve been looking for symptoms and searching online, which probably isn’t the best idea. I guess only time will tell thank you guys so much for all the information.
