Blood glucose values
The following tables list blood glucose values based on the STANDARDS OF MEDICAL CARE IN
DIABETES 2016 from the ADA (American Diabetes Association).
Time of the blood glucose
measurement
Normal blood
glucose values
Increased risk of
diabetes (prediabetes)*
If you have
diabetes
On an empty stomach
(fasting plasma glucose)
Below 100 mg/dL
Below 5.6 mmol/L
100–125 mg/dL
5.6 – 6.9 mmol/L
≥ 126 mg/dL
≥ 7.0 mmol/L
Two hours after an oral
glucose tolerance test
(consumption of 75 g)
Below 140 mg/dL
Below 7.8 mmol/L
140–199 mg/dL
7.8 – 11.0 mmol/L
≥ 200 mg/dL
≥ 11.1 mmol/L
* The risk increases continually, beginning with values below the lower limit of the range and increasing disproportionately towards
the upper limit of the range.
Overview of glycaemic recommendations for non-pregnant adults with diabetes
A1C
< 7.0%*
< 53 mmol/L*
Preprandial capillary plasma glucose
80–130 mg/dL*
4.4–7.2 mmol/L*
Peak value of postprandial capillary plasma
glucose**
< 180 mg/dL*
10.0 mmol/L*
* For individual patients, more or less strict glycaemic targets may be appropriate. The target values should be adjusted depending
on the length of time the person has had diabetes, age/life expectancy, accompanying diseases, known cardiovascular diseases or
advanced microvascular complications, hypoglycaemia unawareness, as well as individual patient considerations.
** The postprandial glucose value can serve as a target value if the A1C values are not met despite the preprandial glucose targets
having been reached. Postprandial blood glucose measurements should be taken one to two hours after the start of a meal, as this
is when diabetics’ values are generally highest.
Critical blood glucose values
Display
Blood glucose
Action
Very low blood glucose
level

(under 1.1 mmol/L)
Immediately seek medical
attention.
Low blood glucose level
