Glycosylated Hemoglobin (HbA1c), EDTA Whole Blood is an important test used to evaluate the average blood glucose levels over the past three months. It measures the percentage of hemoglobin that is bound to glucose in red blood cells, providing a comprehensive overview of blood sugar control. The sample is collected using whole blood treated with EDTA, which helps maintain sample stability and ensures accurate results. This test is considered essential for diagnosing diabetes and monitoring a patient’s response to treatment, helping doctors make informed decisions to improve overall health.
