Three weeks after giving birth to my son I got a call saying he had failed his newborn screening for CF. We went to UVA about a month later for a sweat test. He tested in the "grey" area. After blood work I was told they were only able to find 1 mutation, Delta F508. We then went every 6 months for sweat test. This summer we decided to join a test group that Johns Hopkins was offereing. They were able to find his second mutation... S945L. Our doctor has never worked with anyone who has these 2 mutations. I would LOVE to talk with someone who has this.
