With two slices of whole wheat bread, glucose likewise likely runs 150-180 mg/dl. Glycated haemoglobin, or HbA1c, is the main biomarker used to assess long-term glycaemic control in individuals with diabetes, and it correlates with the development of complications. Q: My PSA 4.31 I M 71 Years, is it normal? A normal hemoglobin A1C (HbA1C or A1C) level is below 5.7%.
