I was in a similar boat as you, although my son is much older, at the time 7. The sweat test was done, 42, so again, 43, and again, 43. The Genzyme test came back neg, so the GI and I were ready to move on. The pulm doc rained on that parade real quick. Then the full Ambry also came back neg and we started looking for other causes. Phone call from the consulting pulm (a CF spec, by the way)to tell us she believes my son's mutations are yet to be discovered. Dx: cystic fibrosis w/ unknown mutations. IMHO I'd definately go for the full panel.
