At the time of his diagnosis, Mike&#8217;s A1C was 15.8%. The normal range of A1C is generally considered between 4-5.7%. (According to <a href=\"https:\/\/www.healthline.com\/diabetesmine\/highest-diabetes-A1C-in-history#1\">DiabetesMine<\/a>, Dr. Francine Kaufman has seen an A1C as high as 22%.)<\/p>\n<p>A hemoglobin A1C blood test reflects a person&#8217;s average blood sugar levels over the course of about three months. Hemoglobin is a protein in red blood cells that carries oxygen, and the A1C test measures how much sugar has &#8220;stuck&#8221; to those cells. The test is used both to diagnose and monitor Type 1 and Type 2 diabetes.<\/p>\n<ol>\n<li>A1C test goes by many other names, including glycated hemoglobin, glycosylated hemoglobin, hemoglobin A1C and HbA1c.\n<\/li>\n<li>The A in A1C stands for adult.\n<\/li>\n<li>In 2013, the FDA approved the first A1C test for <a href=\"https:\/\/asweetlife.org\/first-a1c-test-to-be-approved-by-fda-for-diagnosing-diabetes\/\"><em>diagnosing<\/em> diabetes<\/a>.\n<\/li>\n<li>In people <em>without<\/em> diabetes <a href=\"http:\/\/journals.plos.org\/plosone\/article?id=10.1371\/journal.pone.0171315\">A1C values are higher<\/a> in blacks, Asians, and Latinos when compared to white persons. Although the differences are small, they could have an impact on the use of a sole A1C value to diagnose diabetes in all ethnic populations.<\/li>\n<li>\n<p>For most adults, the American Diabetes Association recommends a target A1C of below 7 percent.\u00a0<a href=\"https:\/\/www.cbsnews.com\/news\/doctors-group-issues-controversial-type-2-diabetes-guidance\/\">New and much debated guidance<\/a> from the American College of Physicians, however, suggests that A1C should be between 7 and 8 percent for most <span class=\"link\">adults with type 2 diabetes<\/span>.<\/p>\n<\/li>\n<li>Iron deficiency anemia is associated with a higher A1C. However, blood loss from surgery, heavy menstrual cycles, other types of anemia may cause an <a href=\"https:\/\/www.thediabetescouncil.com\/ultimate-guide-to-the-a1c-test-everything-you-need-to-know\/\">A1C to be falsely low<\/a>.<\/li>\n<li>\n<p>The <a href=\"https:\/\/www.niddk.nih.gov\/health-information\/diabetes\/overview\/tests-diagnosis\/a1c-test#glucose\">A1C test<\/a> doesn\u2019t show sudden, temporary increases or decreases in blood glucose levels. &#8220;Even though A1C results represent a long-term average, blood glucose levels within the past 30 days have a greater effect on the A1C reading than those in previous months.&#8221;<\/p>\n<\/li>\n<li>An A1C result is an average. It does not necessarily reflect time spent with in-range blood sugars. For example, a person&#8217;s A1C of 6% could be the average of many highs and lows, not simply the result of steady in-range blood sugar.\n<\/li>\n<li>There is no need to fast before an A1C test.\n<\/li>\n<li>It is possible to lower your A1C by making small lifestyle changes, like adding more exercise to your routine, or eating low carb meals and snacks.
