HbA1c measures how much sugar has stuck to your red blood cells over about three months. The ADAG study linked it to average glucose: eAG (mg/dL) = 28.7 × HbA1c − 46.7. So 7% ≈ 154 mg/dL (8.6 mmol/L).
Labs in the UK and Europe report HbA1c in mmol/mol (IFCC units): 48 mmol/mol equals 6.5%, the diabetes threshold.

Finger-prick tests are snapshots, often taken fasting; HbA1c also counts after-meal peaks and night-time levels. Anaemia and pregnancy can also affect HbA1c.
