HbA1c 5.6%

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

Converted value

114mg/dL eAG

An HbA1c of 5.6% converts to an estimated average glucose of about 114 mg/dL — 6.3 mmol/L. In IFCC units the same result is 38 mmol/mol.

Against the American Diabetes Association criteria, 5.6% is below the prediabetes 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 5.6%

The ADAG regression is applied directly: 28.7 × 5.6 − 46.7 = 114.0 mg/dL.
That figure is divided by 18.016, the molar mass of glucose in these units, giving 6.33 mmol/L.
The NGSP master equation converts the percentage to the IFCC unit: (5.6 − 2.15) × 10.929 = 37.7 mmol/mol.
Rounded for display to 114 mg/dL, 6.3 mmol/L and 38 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 5.6 - 46.7        = 114.0 mg/dL
114.0 / 18.016             = 6.33 mmol/L
(5.6 - 2.15) x 10.929   = 37.7 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 5.6% 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 5.6% 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 below the prediabetes range is reassuring at the moment it was taken. It is not a permanent result, and it does not mean testing never needs repeating.

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.

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 5.6% mean?

On the American Diabetes Association criteria, 5.6% is below the prediabetes range. It converts to an estimated average glucose of about 114 mg/dL (6.3 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 5.6% HbA1c in mg/dL?

About 114 mg/dL as an estimated average glucose across the previous two to three months, from eAG = 28.7 × 5.6 − 46.7. That is an average, not a reading you would expect to see on a meter at any particular moment.

What is 5.6% in mmol/mol?

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