Hi , I am a 75 year old male with type 2 for around 10 years. I control by diet--no carbs.-- and metformin and glicklaside and my Hb1c tests are in the 6.8 area. I usually blood test twice a day before going driving in the morning and last thing at night before bed time. I have just bought a pack of Bayer Keto- Diastix urine test strips. I do not fully follow as to what colour on the glucose chart I should be aiming for---the very light green end or the mid-range or above. Help needed please ASAP.
