HbA1c 6.9%
Converted with the published ADAG regression. What it means for you is a question for a doctor, not for this page.
151 mg/dL An HbA1c of 6.9% corresponds to an estimated average glucose of about 151 mg/dL, which is 8.4 mmol/L. In IFCC units the same result is 52 mmol/mol.
Against the American Diabetes Association criteria, 6.9% is at or above 6.5%, which is the threshold for the diabetes range. That is a statement about a published threshold — it is not a diagnosis, and a diagnosis requires confirmation and a doctor.
Nothing here can diagnose you, and nothing here is a treatment plan. Blood glucose results are interpreted by a doctor alongside your history, your symptoms and a repeat test — a single number on a screen is not a diagnosis. If any reading concerns you, or if you feel unwell, see a doctor rather than a website.
The arithmetic
28.7 × 6.9 − 46.7 = 151.3 mg/dL · 151.3 ÷ 18.016 = 8.40 mmol/L
(6.9 − 2.15) × 10.929 = 51.9 mmol/mol
Rounded on this page to 151 mg/dL, 8.4 mmol/L and 52 mmol/mol. The equation is the ADAG regression from Diabetes Care 2008, which is the one the American Diabetes Association uses; the mmol/mol line is the NGSP master equation.

Where 6.9% sits
| HbA1c (%) | mmol/mol | eAG (mg/dL) | eAG (mmol/L) | Where it sits |
|---|---|---|---|---|
| 6.4% | 46 | 137 | 7.6 | In the prediabetes range |
| 6.5% | 48 | 140 | 7.8 | In the diabetes range |
| 6.6% | 49 | 143 | 7.9 | In the diabetes range |
| 6.7% | 50 | 146 | 8.1 | In the diabetes range |
| 6.8% | 51 | 148 | 8.2 | In the diabetes range |
| 6.9% | 52 | 151 | 8.4 | In the diabetes range |
| 7.0% | 53 | 154 | 8.6 | In the diabetes range |
| 7.1% | 54 | 157 | 8.7 | In the diabetes range |
| 7.2% | 55 | 160 | 8.9 | In the diabetes range |
| 7.3% | 56 | 163 | 9.0 | In the diabetes range |
| 7.4% | 57 | 166 | 9.2 | In the diabetes range |
Estimated average glucose is an average across roughly the previous three months. It is not a prediction of your reading tomorrow morning, and two people with the same HbA1c can have very different day-to-day swings.
What this page is careful not to say
It does not tell you whether 6.9% is good or bad for you, because that depends on things a web page cannot see — whether you have already been diagnosed, what else is on your report, whether you have a condition that makes HbA1c unreliable, and what your doctor is trying to achieve. It publishes no targets for anyone.
A result in this range is a reason to see a doctor and follow their advice about repeating the test — not a reason to start any diet, supplement or medicine you read about online.

General information only — NOT medical advice, and never a diagnosis. Only a doctor can interpret your results and diagnose or treat diabetes. If a reading concerns you, see a doctor rather than a website. Every threshold, equation and glycemic index value used on this site is listed with its publication on the data & method page.
