A Review of Non-Invasive HbA1c and Blood Glucose Measurement Methods

Hemoglobin is a protein in Red Blood Cells (RBC) which supplies oxygen to the human body. A person’s hemoglobin becomes glycosylated as per the increase in the level of blood sugar. Glycated hemoglobin (HbA1c) is a widely used measure of glycemic control which measures the glucose attached to hemoglobin. Different methods are adopted and utilized for the measurement of HbA1c. Several invasive methods are widely used in pathological laboratories across the globe. The current status of non-invasive HbA1c and blood glucose measurement techniques is summarized in this paper.
