Fasting is always below 100 mg/dl and PP is below 125 mg/dl. While high blood sugar may be a risk factor for diabetes mellitus, high A1C is not exclusively seen in those with the health condition.In fact, people can have a high A1C even if they don't have a history of diabetes. You could try testing at 1 hour, then 2, then 3 etc to see when your peaks are, and how highthey are, for your typical meals. HbA1c predicts the likelihood of having impaired glucose tolerance in high-risk patients with normal fasting plasma glucose The use of FPG concentration followed by selective measurement of HbA1c in patients who are at high risk of developing diabetes may represent a reasonable approach to identifying patients requiring an OGTT.

The best measure of all is a postprandial glucose one hour after the completion of a meal, a measure you can easily obtain yourself with a home glucose meter. Before the release of this report, diabetes was mainly defined using a fasting plasma glucose 126 mg/dl (7.0 mmol/l) in the U.S ().Using A1C (6.5%) to diagnose diabetes may identify different individuals than fasting plasma glucose because the two methods assess different elements of glucose metabolism ().The purpose of this study was to compare A1C 6.5% and fasting plasma glucose . Fasting plasma glucose level of 7.0 mmol/L or more. According to these guidelines, an A1c of 5.7 to 6.4 percent is used to diagnosed prediabetes, and an A1c of 6.5 percent can be used to confirm the diagnosis of diabetes.

The test for hemoglobin A1c depends on the chemical (electrical) charge on the molecule of HbA1c, which differs from the charges on the other components of hemoglobin. HbA1c also is known as glycosylated, or glycated hemoglobin. According to continuous glucose monitoring studies of healthy people, a normal fasting blood sugar is 89 mg/dL or less. HbA1c in Diabetes: 6.5% or more. Eating a healthy diet is also very important.

As blood glucose levels rise, more glycated hemoglobin forms, and it persists for the lifespan of red blood cells, about four months.2 Therefore, the A1C level directly correlates to the average blood glucose level over the previous 8-12 weeks; A1C is a reliable test that has been refined and standardized using clinical trial data.3 There are two key things to know about the appl HbA1c (Hemoglobin A1c), blood test measures the average blood sugar levles.

In general: An A1C level below 5.7 percent is considered normal An A1C level between 5.7 and 6.4 percent is considered prediabetes An A1C level of 6.5 percent or higher on two separate tests indicates type 2 diabetes Certain conditions can make the A1C test inaccurate such as if you are pregnant or have an uncommon form of hemoglobin (hemoglobin variant).

Diabetes and the A1C Test: What Does It Tell You? HbA1c is a marker that can determine your average blood sugar (glucose) levels over the previous 3-months (1). It is because your body digests the last meal (dinner), and the released glucose is either absorbed or stored in the morning.
