Key Points
- Converts blood glucose between mmol/L (UK, Europe, Australia) and mg/dL (US) using the standard factor of 18.018
- Normal fasting glucose is 3.9–5.5 mmol/L (70–99 mg/dL); pre-diabetes sits at 5.6–6.9 mmol/L (100–125 mg/dL)
- Diabetes is typically diagnosed at a fasting glucose of 7.0 mmol/L (126 mg/dL) or above on two separate occasions
- A single reading is a snapshot. HbA1c gives a 3-month average and pairs well with fasting insulin for a fuller picture
- Values are influenced by recent food, exercise, illness, and stress. Always interpret results with a healthcare professional
