Question

Normal value of HbA1c falls in the range of

• A. 0.1% to 0.8%
• B. 6.5% to 7.5%
• C. 21.5% to 24.5%
• D. 51.5% to 53.5%

Answer 1

The Correct Option is D

The question asks for the normal range of HbA1c values. Hemoglobin A1c (HbA1c) is a form of hemoglobin that is bound to glucose. It is commonly used to gauge long-term blood sugar control in patients with diabetes.

The normal range of HbA1c for non-diabetic adults is typically between 4% and 5.6%. However, the options presented in the question seem inaccurate for the actual medical range of HbA1c, as stated values like 51.5% to 53.5% do not correspond to real HbA1c levels, unless there is a context mismatch in terms of system of expression or question setting.

To clarify, if there was an error in the options provided or if they showed values that are inconsistent with the actual measure of HbA1c, it should be checked or revised. Normally, based on medical standards the correct and general range should be stated as:

• The typical normal range: 4% - 5.6% in usual settings (denoting non-diabetic status).
• Prediabetic range: 5.7% - 6.4%.
• Diabetes typically diagnosed at levels of 6.5% or more.

In terms of logical reasoning for any similar question that had contextually accurate ranges within the options, the normal reference range should always fall within the mentioned medical standards.
