Quick GuideBlood Sugar Swings: Tips for Managing Diabetes & Glucose Levels
How is hyperglycemia diagnosed?
There are different kinds of blood tests that can diagnose hyperglycemia. These include
- Random blood glucose: this test reflects the blood sugar level at a given point in time. Normal values are generally between 70 and 125 mg/dL, as discussed earlier.
- Fasting blood glucose: this is a measurement of blood sugar level taken in the early morning prior to eating or drinking anything since the night before. Normal fasting blood glucose levels are less than 100 mg/dL. Levels above 100 mg/dL up to 125 mg/dL suggest prediabetes, while levels of 126 mg/dL or above are diagnostic of diabetes.
- Oral glucose tolerance test: this is a test that measures blood glucose levels at given time points after a dose of sugar is consumed. This test is most commonly used to diagnose gestational diabetes.
- Glycohemoglobin A1c: is a measurement of glucose that is bound to red blood cells and provides an indication about blood sugar levels over the past 2 to 3 months.
