HbA1c
HbA1c reflects your average blood glucose over roughly the past 2–3 months, giving a longer-range view than a single fasting glucose draw.
Reference range
Watch points
- High: at or above 6.5 %
- Borderline: at or above 5.7 %
Same thresholds apply to men and women in this table.
Why hard-training athletes watch it
Because HbA1c averages months rather than one morning, it catches a slow upward drift through a long bulk that a single fasting glucose reading might miss entirely — pair the two to see both the snapshot and the trend.
When to retest
Retest roughly every 3 months, since the marker itself represents a 2–3 month average — testing more often than that won't show meaningful new information.
Talk to your clinician
Tighten diet and add cardio, and discuss your HbA1c with your clinician. A borderline reading is a signal to tighten diet and add activity, and to discuss a recheck timeline with your clinician — not an emergency.
