What is A1C?
The A1C test, also known as the hemoglobin A1C test, is a crucial tool in monitoring blood sugar control over a period of time. This test measures the percentage of hemoglobin in the blood that has glucose attached to it. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body, and when glucose binds to it, it forms glycated hemoglobin. Since red blood cells live for about three months, the A1C test provides an average of blood sugar levels over that time frame.
A1C testing is valuable because it reflects the body's overall glucose exposure and is not influenced by short-term fluctuations that might occur day-to-day. The results are expressed as a percentage, with higher percentages indicating poorer blood sugar control. It's a standard test for diagnosing diabetes and assessing long-term glucose management in individuals already diagnosed with diabetes.
Why is A1C Important?
A1C testing is particularly important because it helps to identify individuals at risk for diabetes-related complications. High A1C levels are associated with an increased risk of developing complications such as cardiovascular disease, neuropathy, and retinopathy.
