Why it's on the midlife checklist
The three-month average — steadier than any single glucose reading and the standard long-view metabolic number. UK and EU reports use mmol/mol where US reports use percent; Perity records whichever your report says, without silent conversion.
Keeping the record
Log each result in the unit your report uses. The multi-year trend through the transition is the useful shape — a slow drift is exactly what this test exists to catch.
