HbA1c level that indicates poor glycemic control is greater than what percent?

• A. >6%
• B. >`>7%`
• C. >12%
• D. >8%

Answer: (C)

HbA1c shows the average blood glucose over the past 2–3 months, so higher values mean poorer long-term control. While targets are often <7% for good control, very high values indicate especially poor control that requires urgent attention. An HbA1c around 12% corresponds to an average glucose near 300 mg/dL, signaling sustained severe hyperglycemia. Among the given options, the threshold exceeding 12% best represents this level of poor control, whereas lower thresholds indicate suboptimal or poor—but not as extreme—control.
