An a1c of 5.7% to 6.4% means that you are at high risk for the development of diabetes and you have prediabetes. diabetes is diagnosed when the a1c is 6.5% or higher. fasting plasma glucose test (fpg). The hemoglobin a1c test tells you your average level of blood sugar over the past 2 to 3 months. it’s also called hba1c, glycated hemoglobin test, and glycohemoglobin. hemoglobin is a protein. If you don’t have symptoms but the a1c test shows you have diabetes or prediabetes, a falsely high a1c result can occur in people who are very low in iron; for example, those with iron-deficiency anemia. other causes of false a1c results include kidney failure or liver disease..

The a1c test is important in diabetes and prediabetes as a measure of the glucose control during the prior three months. normal values for the hemoglobin a1c are 5.6% or below. values between 5.7% and 6.4% are considered to reflect prediabetes, while values of 6.5% and over are typical for diabetes.. Hemoglobin a1c, often abbreviated hba1c, is a form of hemoglobin (a blood pigment that carries oxygen) that is bound to glucose. the blood test for hba1c level is routinely performed in people with type 1 and type 2 diabetes mellitus .. Symptoms of conditions associated with high hemoglobin levels many underlying medical conditions can lead to increased hemoglobin levels. take a look at the additional symptoms caused by these conditions, so you have a better understanding of what you might be dealing with..

Hyperglycemia (high blood sugar) is the most common cause of diabetes (both type 1 and 2). common symptoms of high blood sugar are increased thirst and the need to urinate often. causes of high blood sugar include lack of or decreased insulin in the blood due to poor medication control, diet, other drugs, and exercise.. High hemoglobin count occurs less commonly because: your red blood cell production increases to compensate for chronically low blood oxygen levels due to poor heart or lung function. you have a bone marrow dysfunction that results in increased production of red blood cells..
