How positive have the tests been?

My son is 7 weeks old. He had a sweat test two weeks ago and it came back at 81. since then, his other tests results have been as follows: Throat culture - normal pancreas - well above normal and dont need to give him the creon anymore live level - normal white blood cells - normal chest x-ray - clear all other blood levels - normal. we are waiting for them to finish the genealogy on his blood to find the other mutation and go back on wed for another sweat test. how likely is it that he doesn't have CF or is just borderline?????
