![]() The test used to determine the percentage of glucose unable to get into cells is called a glycosylated hemoglobin, or hemoglobin A1C, percentage. As a result, you feel chronically tired, and the pancreas works too hard trying to make more insulin. ![]() Insulin, a hormone produced by the pancreas, is required to move glucose out of the blood and into cells but when the cells become overwhelmed by the amount of sugar in the diet, or they become resistant against the action of insulin, the glucose stays outside the cells. This is also the time to correct the amount of glucose floating around in the blood, unable to get into the body's cells where it can be used for energy. Video of the Day Type 2 Diabetes If you're considering having a baby, the time to find out you have diabetes is before you stop using contraception and try to conceive, according to the American Diabetes Association. Having A1C blood testing for diabetes annually means a woman never has to guess. The 2004 National Health and Nutrition Examination Survey reported that 12 percent of women age 18 to 44 have high blood sugar and 26.5 percent are obese. Somīecause women in America are not routinely tested for diabetes before they conceive and between each pregnancy, the incidence of preconception diabetes is unknown but it can be estimated by considering risk factors. Liver disease and some conditions with abnormal haemoglobin decrease the A1c and kidney disease increases it. In normal late pregnancy the red blood cells stay around longer and the A1c normally rises a little, about 0.4 %. Thus a transfusion, or bleeding and the body making new red blood cells will lower the A1c, anemia where the cells hang around longer increases the A1c. If something changes the life span of the red blood cell, this can change the A1c even if the glucose is unchanged. In some countries the units for A1c have changed so 6% is now 42, 8% is 64 and 10% is 86. Thus an A1c of 6.5% is fairly good for someone with Type 1 diabetes, 8.0% would indicate things are not great and 10% or higher the sugars are not controlled. There is a pretty strong correlation between the average blood sugar and the percent A1c. If the blood sugar is high over the last three months (for the life of the red blood cells) then a greater percentage will be glycated. Normally some of the sugar in the blood stream sticks to the A1c (this is called glycation) so that at any given time some 4.1 to 6.1% of the A1c is glycated. They are mainly made of hemoglobin and a sub component of hemoglobin is A1c. Red blood cells survive for 3 months in the circulation. The A1c is a much more stable reflection of overall sugar control. Both have the same average of 11 mmol/l (198 mgs/dl) but the control of sugar in Mr Smith sounds much worse. Consider Mr Smith who has sugars ranging from 2 to 20 mmol/l (36 – 360 mgs/dl) and Mrs Dixon with sugars of 10 to 12 mmol/l (180 – 216 mgs/dl). What is it and is it good at reflecting over sugar levels? Simple average blood sugars are not that great at telling how the blood sugar control is really like. In diabetes a lot of attention is paid to the A1c. What Is A1c And Is It An Accurate Reflection Of Blood Sugar In Pregnancy? Although no test is perfect, the A1C and blood glucose tests are the best tools available to diagnose diabetes-a serious and li Why should a person be tested for diabetes? Testing is especially important because early in the disease diabetes has no symptoms. However, some medical organizations continue to recommend using blood glucose tests for diagnosis. Because the A1C test does not require fasting and blood can be drawn for the test at any time of day, experts are hoping its convenience will allow more people to get tested-thus, decreasing the number of people with undiagnosed diabetes. In 2009, an international expert committee recommended the A1C test as one of the tests available to help diagnose type 2 diabetes and prediabetes.1 Previously, only the traditional blood glucose tests were used to diagnose diabetes and prediabetes. Can the A1C test be used to diagnose type 2 diabetes and prediabetes? Yes. The higher the percentage, the higher a person’s blood glucose levels have been. The A1C test result is reported as a percentage. Thus, the A1C test reflects the average of a person’s blood glucose levels over the past 3 months. In the body, red blood cells are constantly forming and dying, but typically they live for about 3 months. How does the A1C test work? The A1C test is based on the attachment of glucose to hemoglobin, the protein in red blood cells that carries oxygen. The A1C test is the primary test used for diabetes management and diabetes research. The A1C test is sometimes called the hemoglobin A1c, HbA1c, or glycohemoglobin test. What is the A1C test? The A1C test is a blood test that provides information about a person’s average levels of blood glucose, also called blood sugar, over the past 3 months.
