Cystic Fibrosis Newborn Screen

I am so confused. ☹️ My 1 week old newborn test came back as a moderate risk for cystic fibrosis. The pediatrician said the number was 70’s but didn’t really explain what number was good. We are going to get the sweat test done to check further into this. My question is, I had the screening done and it came back negative for carrier gene. We never had my husband tested because of that and our first born was never diagnosed with anything and is healthy. Any insight?! Since I am not a carrier, what should I expect for my newborn? Any advice and info is welcomed!
