My son's,(22 yrs.old mostly sinus symptoms - 3 surgeries) sweat test just came back positive(?) with a 53. Should he have the test again ? It was done at the local hospital. I've heard that there are more false positives than false negatives - anybody know about this? Also, anyone use a center in the Chicago area? Loyola University is closer for us and also in our insurance network. Thanks.
