CFF recommends starting GTT at age 10, so last week when DS had his regular blood work, they also had him do a 2 hour GTT. Drew blood after fasting, drank a cup of orange flavored sugary stuff, then another blood draw after two hours. Fasting Level was normal 87 (range is 70-100 mg/dL), but his two hour was 155. Got a form letter from his pediatrician/local CF doctor who suggested two weeks of testing with a glucometer fasting/2 hours after meals; however, the CFF guidelines suggest another GTT next year. DS has a terrible, terrible needle phobia and while we will do it if it's absolutely necessary, I'd prefer waiting. Waiting to hear what his primary CF doctor in the City suggests. Friend of mine's daughter's showed reactive hypoglycemic and she just has to eat every two hours.... Guess I'll just wait and see what the powers that be suggest.
