Hi all. I recently had a blood test to see if I was diabetic and received a letter from my GP asking me to make an appointment with his clinic to talk about my glucose management and to have a second blood test. As he didn't say it was urgent, I decided to wait until after my two week holiday in the USA (where I am now). Last night, after dinner, a friend who is both a nurse and a diabetic herself, took my glucose reading, and was shocked to find it 23 mmo/l. I feel ok but am scared now because I have read that this is dangerously high. What should I do?
