Re: Children and Blood Sugar Numbers
if this reading is 1 hour after a meal, I think he is fine. You shouldn't be concerned. However, I'm not a doctor, only his ped. can answer you.
My advice is to test him early in the morning, i.e. fasting test. And I expect a normal reading because of the 130 reading you got.
Generally, random tests (like the one you have done) can't indicate or diagnos the disease. Unless it's 200+, it has no meaning. Only fasting tests are indicative of the disease.
So you better test him while he is fasting. Anything under 100 is normal, 100-126 suggest pre-diabetes. Any reading higher than 126 can diagnos diabetes, but it has to be confirmed by another test.
Best wishes to your son,
