A non-fasting glucose test measures the amount of glucose (sugar) in your blood after eating. Normal non-fasting glucose levels are below 140 milligrams per deciliter of blood (mg/dL). If they're between 140 and 199 mg/dL, you may have prediabetes. If they're above 200 mg/dL, you may have diabetes.
Non-fasting blood sugar levels may indicate that an individual is prediabetic or diabetic based on the following ranges. Normal: 140 mg/dL or lower; Prediabetes: 140 mg/dL to 199 mg/dL
For some people with diabetes, a fasting blood sugar measurement of 120 is on the high end of normal. For people without this condition “normal” is lower -- under 100 except right after meals. Normal blood sugar levels differ depending on a person’s age and other health conditions.
If your blood glucose or A1C levels are high, a healthcare professional will likely recommend further testing to confirm a diagnosis of prediabetes or diabetes.
We have a chart below offering that glucose level guidance based on age, to use as a starting point in deciding with your healthcare professionals what might be best for you.
According to the National Institutes of Health (NIH), normal blood sugar levels for people without diabetes are typically 70 to 99 mg/dL (3.9 to 5.5 mmol/L) fasting, with after-meal levels generally not exceeding 140 mg/dL (7.8 mmol/L).
Normal non-fasting blood sugar levels should be less than 180 milligrams per deciliter (mg/dL) for those with diabetes, according to the ADA. For those without diabetes, it's less than 140 mg/dL, according to Virginia Mason Diabetes Care.
When you’re diagnosed, your doctor will give you a target blood sugar (glucose) range. That’s your goal range to stay healthy and avoid complications like nerve damage and kidney disease....
Since eating food affects blood sugar, fasting blood glucose tests show a more accurate picture of your baseline blood sugar. There’s also at-home blood sugar testing (using a glucometer) for people who have diabetes.
Doctors use blood sugar charts, or glucose charts, to help people set goals and monitor their diabetes treatment plans. Charts can also help people with diabetes understand their blood...
