Range of fasting and random glucose levels?

I was diagnosed type 2 last year and had to control it with my diet but last weeks fasting blood test result was 10.2 and the doctor has now started me on Metformin to control it. Anything above 9 needs medication. Your strips mean fasting result should be as level 1 which is normal and level 2 means medication needed and these numbers are very high and anything at 19 needs hospital attention urgently. Hope this helps but you might find out more from the diabetic websites. Good Luck.
