Hi. I assume you are using USA units (mg/dl) and talking about fasting readings not HBa1C? . This figure, which equates to 6.1mmol for fasting blood test in the UK, is within a 'good' range. The number for either fasting or HBa1C can never be an absolute as people vary in their natural non-diabetic sugars. The health experts in the UK and USA set limits to be within a range where any damage is expected to be low or none. Going above these limits is likely to gradually increase the risk of capillary damage. No one really knows the rate of increase in damage as limits are exceeded.
