Is a1c a good indicator of diabetes?
A1c diabetes test is a better indicator of risk. WASHINGTON (Reuters) - A test that shows blood sugar levels over a span of several weeks is not only the best way to diagnose diabetes but also may be better at identifying who is at risk of getting diabetes than standard blood sugar tests, researchers said on Wednesday.
Accordingly, is a1c the best test for diabetes?
“While the American Diabetes Association guidelines specify that diabetes can be diagnosed based on fasting plasma glucose (FPG), the OGTT, or the A1c, our findings confirm that reliance on A1c remains the least reliable method for assessing diabetes risk.”
Similarly, what is the most accurate test for diabetes? Three blood tests are considered the most accurate for diagnosing prediabetes and diabetes: Fasting plasma glucose test measures blood sugar level after an overnight fast (eight to 12 hours) and has been the standard initial diagnostic method for decades.
Keeping this in view, can you still have diabetes if your a1c is normal?
For someone who doesn't have diabetes, a normal A1C level is below 5.7 percent. If your A1C level is between 5.7 and 6.4 percent, you have prediabetes (also called impaired fasting glucose), which means you have a high risk of developing diabetes in the future. This may make your A1C test results falsely low.
What is more accurate glucose or a1c?
But in people with diabetes, who have more sugar in the bloodstream, the percentage can reach 15% or higher. The hemoglobin A1c number reflects your average blood sugar over the past 2-3 months. It's a way to gauge long-term glucose control, or lack of it.
