Glycated Haemoglobin (IFCC)

Glucose Metabolism marker

HbA1c (IFCC)

Glycated Haemoglobin (IFCC)

Category: Glucose Metabolism
Unit: mmol/mol

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
