How HbA1c appears on your report
Look for Glycated Haemoglobin (HbA1c). The result is normally shown in mmol/mol, next to the reference interval used by the laboratory that ran the test.
Note the collection date before you compare it with anything, along with the context that matters for this marker: recent glucose changes take time to show. Iron deficiency, anaemia, kidney disease and conditions that change red-cell lifespan can affect it.
HbA1c range in Australia
Vector tracks HbA1c against an optimal range of 20–38 mmol/mol. Australia has no nationally harmonised reference interval for this marker, so the interval printed on your report varies with the laboratory and the assay it used.
Vector’s optimal range is the band the app tracks against and the one printed in the doctor report. Why the two differ.
What to read alongside HbA1c
A single marker rarely explains itself. These results are commonly interpreted together with HbA1c, and Vector keeps them within reach of each other as your record grows.
Tracking HbA1c over time
One HbA1c result is a single point. Import the report into Vector, check the extracted value, unit and collection date, and it becomes the start of a series instead — with each later report adding a dated point you can actually compare against.

Common questions
What is a normal HbA1c range in Australia?
Australia has no nationally harmonised reference interval for HbA1c, so the range printed on your report varies with the laboratory and the assay it used — always read your result against the interval beside it. Vector tracks HbA1c against an optimal range of 20–38 mmol/mol, which is deliberately tighter than a population reference interval.
What is the optimal HbA1c level?
Vector treats 20–38 mmol/mol as the optimal range for HbA1c. An optimal range is a target the app tracks against, not a clinical threshold, and it can differ from the interval your laboratory prints.
What unit is HbA1c reported in on Australian pathology reports?
HbA1c is usually reported in mmol/mol on Australian pathology reports. The performing laboratory prints a reference interval in the same unit beside the result, and that interval is the one that governs your individual result.
What can change your HbA1c result?
Recent glucose changes take time to show. Iron deficiency, anaemia, kidney disease and conditions that change red-cell lifespan can affect it.
