HbA1c

Meaning

HbA1c, or Glycated Hemoglobin, is a crucial clinical measurement that reflects the average plasma glucose concentration over the preceding two to three months. This blood test quantifies the percentage of hemoglobin in red blood cells that has been irreversibly bound to glucose, a process known as glycation. Clinicians utilize the HbA1c value as a primary diagnostic and monitoring tool for diabetes and prediabetes, offering a long-term view of glycemic control that is superior to a single fasting glucose measurement.
