How is an HbA1c test performed and what happens during the blood sample collection?

The HbA1c test is a simple blood test that involves drawing a small blood sample from a vein in your arm or through a finger-prick method. The blood is sent to a laboratory for analysis to measure the percentage of glycated haemoglobin. The procedure is quick and minimally invasive, causing only slight discomfort. You don’t need any special preparation, and results are typically available within a day or two, depending on the lab. The test provides a reliable estimate of your blood sugar control over the past few months.
