Can the HbA1c test replace daily blood glucose monitoring?

No, the HbA1c test cannot replace daily glucose monitoring. While the HbA1c test provides a snapshot of long-term blood sugar control, it doesn’t show day-to-day fluctuations. Regular self-monitoring of blood glucose (SMBG) is essential, especially for patients using insulin or those prone to blood sugar spikes and drops. Daily monitoring helps you and your doctor make real-time adjustments to your diabetes management plan. Both HbA1c and daily glucose checks complement each other to give a full picture of how well your blood sugar is controlled.
