HbA1c 11.0%

Converted with the published ADAG regression. What it means for you is a question for a doctor, not for this page.

Converted value

269mg/dL eAG

An HbA1c of 11.0% converts to an estimated average glucose of about 269 mg/dL — 14.9 mmol/L. In IFCC units the same result is 97 mmol/mol.

Against the American Diabetes Association criteria, 11.0% is at or above 6.5%, which is the threshold for the diabetes range. That describes where the value sits on a published scale. It is not a diagnosis, and a diagnosis requires confirmation and a doctor.

Central estimate, not a reading. The regression explained about 84% of the variation, so real averages sit either side of this figure.

This page is reference information, not medical advice.

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 behind 11.0%

The ADAG regression is applied directly: 28.7 × 11.0 − 46.7 = 269.0 mg/dL.
That figure is divided by 18.016, the molar mass of glucose in these units, giving 14.93 mmol/L.
The NGSP master equation converts the percentage to the IFCC unit: (11.0 − 2.15) × 10.929 = 96.7 mmol/mol.
Rounded for display to 269 mg/dL, 14.9 mmol/L and 97 mmol/mol — the precision laboratories report.
Nothing on this page is interpreted. Where the value sits against a published band is a fact about the band; what it means for a person is a clinical judgement.

28.7 x 11.0 - 46.7        = 269.0 mg/dL
269.0 / 18.016             = 14.93 mmol/L
(11.0 - 2.15) x 10.929   = 96.7 mmol/mol

Provenance

The equations, and who published them

The regression is the ADAG equation from Diabetes Care 2008, which is the one the American Diabetes Association uses; the mmol/mol line is the NGSP master equation. Neither was adjusted here.

Where 11.0% sits

HbA1c converted to estimated average glucose with the ADAG regression, eAG (mg/dL) = 28.7 × A1C − 46.7. The mmol/mol column is the IFCC unit, from the NGSP master equation. The final column reads the A1C against the ADA diagnostic bands.

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 11.0% 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.

PeakForm is a training and accountability programme. It is not a treatment for diabetes or prediabetes, it is not a substitute for your doctor's advice, and nothing on this site should be acted on before speaking to one.

Questions this report anticipates

What does an HbA1c of 11.0% mean?

On the American Diabetes Association criteria, 11.0% is at or above 6.5%, which is the threshold for the diabetes range. It converts to an estimated average glucose of about 269 mg/dL (14.9 mmol/L) using the ADAG equation. A single value is not a diagnosis — published criteria require confirmation, and interpretation belongs to a doctor.

What is 11.0% HbA1c in mg/dL?

About 269 mg/dL as an estimated average glucose across the previous two to three months, from eAG = 28.7 × 11.0 − 46.7. That is an average, not a reading you would expect to see on a meter at any particular moment.

What is 11.0% in mmol/mol?

97 mmol/mol, using the NGSP master equation (percentage − 2.15) × 10.929. Both units describe the same measurement.
