A Hemoglobin A1c test is used to evaluate glucose levels in the bloodstream over 2-3 months prior to having the test completed. This test is very important to monitor in Diabetes management. Scientists believe that keeping blood sugar in the body within a normal range can help individuals with diabetes avoid many of the associated risks and side effects that they often face. The benefit of the hemoglobin A1c blood test is that it provides information on overall glycemic health over a several month period. Other blood tests that measure glucose levels are highly sensitive for determining blood sugar levels at the time that the test is taken; although they do not give information on average glucose levels (which HgB A1C does). Hemoglobin is stored in red blood cells. When glucose levels are elevated, sugar begins to combine with hemoglobin. It takes the body 8-12 weeks to bring hemoglobin A1c levels back down to normal. Therefore, if hemoglobin A1c levels are elevated, this usually means that there has been a high level of glucose in the blood over the last 2-3 months.
