Your HbA1c as a number you can picture: the average blood glucose it corresponds to across roughly three months.
| Result | Band |
|---|---|
| A1c under 5.7% (eAG under 117) | Normal |
| A1c 5.7 to 6.4% (eAG 117 to 137) | Prediabetes |
| A1c 6.5% and above (eAG 140+) | Diabetes range |
eAG = 28.7 × A1c − 46.7, from the ADAG study. A1c categories follow the American Diabetes Association.
BloodMarker reads your whole panel and tells you what the lines say together, which is the part no single calculation can do.

It converts your A1c into the average glucose concentration it represents, so it can be compared with meter or CGM readings.
A1c reflects roughly three months and is affected by red blood cell lifespan. Anaemia, recent blood loss and some haemoglobin variants all shift it.
