HbA1c is an important indicator of long-term glycemic control with the ability to reflect the cumulative glycemic history of the preceding two to three months. HbA1c not only provides a reliable measure of chronic hyperglycemia but also correlates well with the risk of long-term diabetes complications.

Patients do not need to fast before the test is given, and it is far less likely to identify clinically irrelevant fluctuations in blood sugar because it measures average blood glucose levels over several months. The new guidelines do not call for replacing traditional screening with the A1C test.

A hemoglobin test is often used to check for anemia, a condition in which your body has fewer red blood cells than normal. If you have anemia, your cells don't get all the oxygen they need.

“HbA1c is likely to be affected by iron deficiency and iron deficiency anaemia with a spurious increase in HbA1c values. This may lead to confusion when diagnosing diabetes using HbA1c,” the authors say.

It is dependent on the glycation of red blood cells over time. Several variables can affect the HbA1c value, leading to a false-positive or false-negative result, which can significantly affect clinical management.

An A1c Of Greater Than 5.4% Can Signal Undiagnosed Diabetes At-risk individuals with an HbA1c test level of 5.4% or greater can signal undiagnosed diabetes and certainly prediabetes, according to new study findings.

People with diabetes should have an A1c test every three months to make sure their blood sugar is in their target range. If your diabetes is under good control, you may be able to wait longer between the blood tests. But experts recommend checking at least two times a year.

Normal HbA1c A result of 40 or lower is normal for people without diabetes.

Performed by your doctor during your regular visits, your A1C test measures your average blood sugar levels by taking a sample of hemoglobin A1C cells—a component of your red blood cells. Here's how it works: Some blood sugar (or glucose) naturally attaches itself to A1C cells as they move through your bloodstream.

How often should you get your blood sugar checked? Get your blood sugar checked annually if you have prediabetes—higher-than-normal blood sugar levels. Your risk factors determine whether you should be screened annually or every three years.

A study has found that levels of hemoglobin A1C — a biomarker frequently used to diagnose and manage diabetes — are significantly lower in African-Americans with sickle cell trait, compared to those without.

For these blood glucose tests used to diagnose diabetes, you must fast at least 8 hours before you have your blood drawn.

The lower HbA1c levels experienced by people with sickle cell trait could lead to doctors underestimating the risk of prediabetes or diabetes and could lead to delayed diagnoses.

HbA1c levels between 5.7% and 6.4% (39–47 mmol/mol) indicate increased risk of diabetes (prediabetes) Diabetes is defined as HbA1c > 6.5% (48 mmol/mol) For people with diabetes, an HbA1c of 6.5% (48 mmol/mol) is considered good control.

OBJECTIVE—Mean blood glucose (MBG) over 2–3 months is a strong predictor of HbA1c (A1C) levels. Glucose instability, the variability of blood glucose levels comprising the MBG, and biological variation in A1C (BV) have also been suggested as predictors of A1C independent of MBG.
