Glycated Haemoglobin (IFCC)
Glucose Metabolism marker
HbA1c (IFCC)
Glycated Haemoglobin (IFCC)
IFCC-standardised HbA1c measurement. Same marker as HbA1c % but in SI units. Normal: <42 mmol/mol. Pre-diabetes: 42-47. Diabetes: >=48. Conversion: mmol/mol = (% - 2.15) x 10.929.
PED Notes
Equivalent to HbA1c % — same clinical significance. GH use can worsen HbA1c over time, indicating insulin resistance. High haematocrit from AAS can affect accuracy of some HbA1c assays. Australian labs report both units; mmol/mol is the IFCC standard.
Same marker as HbA1c % -- identical management applies (see HbA1c marker).
IFCC units (mmol/mol) are simply a different scale. Targets: <37 mmol/mol optimal for athletes (<5.5%). Conversion: mmol/mol = (% - 2.15) x 10.929.
Supplements:
- Berberine -- 500mg 2-3x/day
- Alpha-Lipoic Acid (ALA) -- 300-600mg/day
Lifestyle:
- Low-glycaemic diet, regular cardio and strength training
- If HbA1c trending upward on GH, consider dose reduction
