HbA1c

HbA1c, or glycated hemoglobin, is a blood test that measures the average level of blood sugar (glucose) over the past two to three months. Hemoglobin is a protein in red blood cells that carries oxygen, and when glucose attaches to it, it forms HbA1c. Higher levels of HbA1c indicate poorer blood sugar control, which is an important factor in diagnosing and managing diabetes. Doctors use HbA1c results to assess how well diabetes is being managed and to adjust treatment plans accordingly. Normal HbA1c levels typically range from 4% to 5.6%.
