What numbers should you be looking for in your blood sugar testing?
While individual goals will vary, there are some general guidelines that are suggested by diabetes professionals.
The American Association of Clinical Endocrinologists (AACE) recommends the following general blood sugar testing goals for adults with type 1 and type 2 diabetes:
- Preprandial (fasting, or before a meal) — <110 mg/dl (6.1 mmol/l)
- Two hours postprandial (after the start of a meal) — <140 mg/dl (7.8 mmol/l)
- A1C (three month blood sugar average) — 6.5% or lower
The American Diabetes Association (ADA) suggests slightly different targets*:
- Preprandial — 80-130 mg/dl (3.9-7.2 mmol/l)
- Postprandial (1-2 hours) — <180 mg/dl (<10.0 mmol/l)
- A1C (three month blood sugar average) — 7.0% or lower for adults, <7.5% for all pediatric age groups
- eAG (estimated average glucose)** — 154 mg/dl equals 7% A1C, 126 mg/dl equals 6% A1C
* These goals are for non-pregnant adults who have no history of severe hypoglycemia. Less stringent goals may be needed for some people, such as those who regularly have severe low blood sugar episodes, older people, people with health problems, and children and adolescents.
** Estimated average glucose, or eAG, is a format your healthcare professional uses for providing your A1C result. The eAG result is reported in the same units as you use for blood sugar monitoring when your blood sugar is checked by the medical lab.
The American Diabetes Association recommends slightly higher A1C goals for young people:
- Children under 19 years old: Less than 7.5%

My diabetes is changing. Until a few years ago, my morning readings were reasonable and within the desired range of under 100 mg/dl. About two years ago, they started slipping upwards into the less-desirable but apparently not-worrisome range of 100-110 mg/dl. Now, this was what was recorded by my Abbott Freestyle Lite meter, which is known to record at the lower end of the home-glucometer variability range, but with my A1c firmly in the high 5s and low 6s, the meter's tendency to...
