Chaser, great info.
Matter of fact, my grandaughter and my "new" grandson were tested via dna and sweat chloride also. My twins are affected with CF but my daughter is a carrier only. Her children were tested soon right after birth. We are still waiting on the results of my newborn grandson's CF blood test.
My daughter has a carrier status of the Delta F508, as my twin boys have CF and their mutation status is the Delta F508.
