thank you so much to everyone who's taken time to read this and post a reply, they have been very helpful.
sorry not to have been clearer from the start - where we are is that I took my son to the GP cos I was concerned about the various symptoms he has been showing. she did a finger prick test in the surgery which showed a reading of 9.8. this was in the late afternoon before he had had an evening meal although he had eaten a toasted buttered muffin (bread not cake) about an hour before as his home from school snack.
she sent us for a full fasting blood test and we are still waiting for those results. am I right in thinking that if that shows a blood sugar of over 7 they will definitly diagnose diabetes based on that and his symptoms? and that it will be Type 1 diabetes? I have been reading a book on childhood diabetes from the library......
I just don't know what to do in the meantime and am trying not to worry myself sick and beat myself up over not having realised earlier something was wrong if the diagnosis is confirmed.
and I am trying to think what I need to tell the GP or ask if it is.
my son is being quite laid back about it so far, I got cream from the GP to numb his inner elbow for the blood test which worked oK but he was rather alarmed by the - to him - large amount of blood they took - three syringe fulls. he was v nervous before the blood test and asked several times if the cream was the same as the 'magic cream' they used to use to numb the back of his hand to put a cannula in many times when he was so ill as a little one - that never worked v well and is where the needle phobia comes from. I told him it was much more effective and was for bigger boys, as they could only use baby cream on babies, and he seemed reassured, especially as it did work.
he knows we will have to go to the doctor again when the test results come back and has asked several times if she will prick his finger again, cos to him that really hurt. he has also asked if he will have to go to hospital, and I've had to say I don't know. it depends what the tests show. I think if we do have to go to a hospital he will find that hard.
so will I, especially as I promised myself after he finally got better when he was little that I would never again let anyone medical do anything that hurt him cos I can't face having to help hold him down or anything like that. not so easy with a big strong 10 yr old, either. I dread being in that sort of aituation again, where junior doctors or nurses turn out to be less expert than you would like - I did at one point refuse to let a junior doctor who was struggling to get a cannula into a terrified little boy to carry on, and insisted they get someone who could do the procedure better but it was v traumatic. I was so frightened and angry myself I threw a big fit

and told the man he should go away and practice on guinea pigs before touching children and that my vet had never caused my horse as much trauma as he had my child and he should be ashamed of himself.

please I don't want to go there again.
sorry for the rant. it is difficult to discuss this with my husband as he is I think just as scared as me but more of the long term implications whereas I know it is me who will have to deal with the immediate concerns. which is why I need people like yourselves to talk to.
thanks for listening.
