hello
i want to know if it is possible for the full genetic testing for cf can come back negative and still have cf. my sons sweat tests were in the 40s and he had the screening for the 32 mutations done that was neg. so they sent his blood to a lab is california for 10wks and that was neg. the lung center was kind of stumped but they have patients with cf that present like this. he was in the hospital bc he got hit by a gastointestinal virus that wiped his body out. they never found out the specific virus but decided to test him with cf. his pancreas was not working but now it slowly is. a gi doctor said a virus could do this to your system but why the positive sweat test.
