HbA1c is the gold standard for assessing diabetes control.
Is it true that HbA1c is the gold standard for assessing diabetes control?
Partly. While hemoglobin A1c (HbA1c) remains the traditional gold standard for assessing long-term diabetes control, its limitations in capturing short-term glycemic variability, postprandial spikes, and red-cell lifespan anomalies have led to a contested landscape where continuous glucose monitoring and alternative biomarkers are increasingly recognized as essential.
Verdict: CONTESTED · 7 sources for, 4 against · Last checked
The retrieved papers universally acknowledge HbA1c as the traditional central biomarker for assessing long-term diabetes control (supporting papers 0, 2, 5, 6, 7, 8, 9). However, multiple papers highlight significant limitations, such as discordance with continuous glucose monitoring, inability to capture short-term glycemic variability, and unreliability in specific pathological conditions (against papers 1, 3, 4, 10). Because alternative methods and markers are increasingly utilized to address these shortcomings, the status of HbA1c as an undisputed 'gold standard' is contested by modern multimodal approaches.
