70-100 mg/dL
1 A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. 2  A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. 3  If it's 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes. 4  Oral glucose tolerance test. 1 Oral glucose tolerance test. 2  For this test, you fast overnight, and the fasting blood sugar level is measured. 3  Then you drink a sugary liquid, and blood sugar levels are tested periodically for the next two hours. 4  A blood sugar level less than 140 mg/dL (7.8 1 The doctor tests your blood sugar level after fasting for 8 hours and it’s higher than 126 mg/dL. 2  Oral glucose tolerance test. 3  After fasting for 8 hours, you get a special sugary drink. 4  Two hours later your sugar level is higher than 200. 5  Random check.  Fasting test results. The results of a fasting test with respect to glucose levels in the body are as follows: 1  Normal: 3.9 to 5.5 mmols/l (70 to 100 mg/dl). 2  Prediabetes or Impaired Glucose Tolerance: 5.6 to 7.0 mmol/l (101 to 126 mg/dl). 3  Diagnosis of diabetes: more than 7.0 mmol/l (126 mg/dl).  1 A blood sample will be taken after an overnight fast. 2  A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. 3  A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. 4  If it's 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes. 1 Oral glucose tolerance test. 2  For this test, you fast overnight, and the fasting blood sugar level is measured. 3  Then you drink a sugary liquid, and blood sugar levels are tested periodically for the next two hours. 4  A blood sugar level less than 140 mg/dL (7.8 A normal fasting blood glucose target range for an individual without diabetes is 70-100 mg/dL (3.9-5.6 mmol/L). The American Diabetes Association recommends a fasting plasma glucose level of 70–130 mg/dL (3.9-7.2 mmol/L) and after meals less than 180 mg/dL (10 mmol/L). A person with prediabetes has a fasting blood glucose level between 100 and 125 mg/dl. If the blood glucose level rises to 126 mg/dl or above, a person has diabetes.&quot; and &quot;•An A1C 5.6% or below is normal. In prediabetes, A1C levels range between 5.7%-6.4% First of all, the levels of sugar in your blood measured after you've been fasting for at least 8 hours are considered as fasting. As you may see from the chart above, the normal results vary from 70 to 100 mg/dl. Meanwhile, if you get 100 to 125 mg/dl, this means that you may have pre-diabetes.

Remember: you need another tests to confirm your diabetes diagnose. The American Diabetes Association recommends a fasting plasma glucose level of 90-130 mg/dL (5.0-7.2 mmol/L) and after meals less than 180 mg/dL (10 mmol/L). If your doctor feels that you are pre-diabetic it would be okay to check a fasting blood sugar at home once a week or so. A person with prediabetes has a fasting blood glucose level between 100 and 125 mg/dl. If the blood glucose level rises to 126 mg/dl or above, a person has diabetes.&quot; and &quot;•An A1C 5.6% or below is normal. In prediabetes, A1C levels range between 5.7%-6.4%
