The normal range for a glucometer, specifically when measuring fasting blood glucose, is between 70 mg/dL (3.9 mmol/L) and 100 mg/dL (5.6 mmol/L).
Here's a breakdown of what these numbers mean, according to the World Health Organization (WHO):
-
Normal Fasting Blood Glucose: 70 to 100 mg/dL (3.9 to 5.6 mmol/L).
-
Prediabetes (Impaired Fasting Glucose): 100 to 125 mg/dL (5.6 to 6.9 mmol/L). The WHO recommends lifestyle changes and monitoring glycemia when levels are in this range.
This table summarizes the information:
| Category | Blood Glucose (mg/dL) | Blood Glucose (mmol/L) | Action Recommended |
|---|---|---|---|
| Normal | 70 - 100 | 3.9 - 5.6 | None |
| Prediabetes | 100 - 125 | 5.6 - 6.9 | Lifestyle changes and monitoring glycemia advised |
It's important to note that these ranges apply to fasting blood glucose levels, typically measured after an overnight fast (at least 8 hours without eating). Blood glucose levels will naturally fluctuate throughout the day depending on food intake and activity levels. Always consult with a healthcare professional for personalized advice and interpretation of your glucometer readings.
