What It Measures
The percentage of hemoglobin proteins in red blood cells that have been glycated (sugar-coated), reflecting average glucose exposure over 90 days.
HbA1c reflects your average blood sugar over the past 2-3 months. It measures the percentage of hemoglobin that has glucose attached to it.
Current Value
What High Means
Elevated HbA1c (5.7-6.4% = prediabetes, ≥6.5% = diabetes) indicates chronic hyperglycemia and metabolic dysfunction. Strong predictor of diabetes complications.
Possible Symptoms
Often asymptomatic in prediabetic range; at diabetic levels: thirst, frequent urination, fatigue
What Low Means
Very low HbA1c (<4%) may indicate hemolytic anemia, blood loss, or other red blood cell abnormalities rather than excellent glucose control.
Possible Symptoms
Fatigue, pallor if due to anemia
Risk Factors
Type 2 diabetes, cardiovascular disease, kidney disease, neuropathy
