Glycosylated hemoglobin A1c test (HbA1c test)

The glycosylated hemoglobin A1c test, also known as the HbA1c or glycated hemoglobin A1c test, is a type of lab test which reveals the average plasma glucose concentration over a period of three months. Specifically, it measures the number of glucose molecules attached to hemoglobin. Results are expressed as a percentage, with 4% to 6% considered to be normal. This test provides information regarding a patient’s possible risk of developing diabetes. By measuring the percentage of sugar-coated hemoglobin, a practitioner can determine a patient’s level of blood sugar control. Higher percentages of sugar-coated hemoglobin typically indicate a higher risk of developing diabetes. Tests such as these may be required prior to dental surgery as they provide insight into health conditions that could possibly hinder the healing process post-surgery. Patients shown to have higher A1c levels may first be required to address their blood sugar levels prior to having a procedure.
