Hgb A1c Levels

Glycohemoglobin (hba1c, A1c)

A glycohemoglobin test, or hemoglobin A1c, is a blood test that checks the amount of sugar (glucose) bound to the hemoglobin in the red blood cells. When hemoglobin and glucose bond, a coat of sugar forms on the hemoglobin. That coat gets thicker when there's more sugar in the blood. A1c tests measure how thick that coat has been over the past 3 months, which is how long a red blood cell lives. People who have diabetes or other conditions that increase their blood glucose levels have more glycohemoglobin (sugar bound to hemoglobin) than normal. An A1c test can be used to diagnose prediabetes or diabetes. The A1c test checks the long-term control of blood glucose levels in people with diabetes. Most doctors think checking an A1c level is the best way to check how well a person is controlling his or her diabetes. A home blood glucose test measures the level of blood glucose only at that moment. Blood glucose levels change during the day for many reasons, including medicine, diet, exercise, and the level of insulin in the blood. It is useful for a person who has diabetes to have information about the long-term control of blood sugar levels. The A1c test result does not change with any Continue reading >>

    As Liang-Hai and the other answerers have shared, a haemoglobin A1c of 5.5% is considered ‘normal’ based on most clinical guidelines. The American Diabetes Association (ADA) considers an A1c of >5.6% to be prediabetes.
    I would add a few more points:
    The cut-off A1c and glucose levels for diagnosing prediabetes and diabetes are arbitrary levels defined by scientists and doctors. These may change over time as we understand diabetes as a disease better (there’s still so much we’re learning about it). The important thing to realise is that in reality the progression from normal -> prediabetes -> diabetes is a continuous spectrum, and not a categorical progression. I remember an interview with a world-famous endocrinologist, and when asked what he would want his own A1c to be ideally, he said it was 5.0%.

    There is a margin of error for the A1c blood test (particularly if you used a home A1c test kit), and the result can be affected by other medical conditions such as anemia. If you had a fasting glucose blood test done, that would be useful in determining where you are.

    It is normal.
    From Hemoglobin A1c Testing

    The reference range for healthy adults is 4.8–5.9%
    From https://www.researchgate.net/pro...

    A single A1C measurement served as the reference method and was used to define two levels of dysglycemia, ≥5.7% (39 mmol/mol) and ≥6.0% (42 mmol/mol), and type 2 diabetes, ≥6.5% (47.5 mmol/mol)
    From https://www.researchgate.net/pro...

    there is some controversy surrounding HbA1c-defined prediabetes ranges, with some favouring 6.0 – 6.4% (42 - 46 mmol/mol)
    So however so define prediabetes, your HBA1c value of 5.5% is wholly normal.

    Who told you “it is moving towards diabetes”, what qualifications does this person have medically speaking?

    No way this is moving towards diabetes. HbA1c is the new marker for Diabetes, but your level is under the permissible limits. Since the no of cases of diabetes is cropping up, and even 10 year old presenting its symptoms, HbA1c is a prognostic tool to access the level of sugar 90-120 days prior to the current date. Keep calm and relax, your's is under the prescribed level. If you feel that you might have diabetes, monitor these things in 24 hours, and then consult your doctor. He is a your best friend you see.
    1. The amount of water that you're consuming. Keep it between 2-2.5 liters if you have a sedentary lifestyle. Or are you consuming more?
    2. How frequently are you hungry, do you keep hungry for long time, or is there craving for food in shorter duration?
    3. Most important of all how frequently do you void yourself, see that it is not more than 6-8 times a day. Is it more?
    You might be having diabetes if answer to any of the questions above is yes. You can then get your fasting sugar (overnight fasting of 8 hours) checked and repeat the test after 15 days. If the both the levels remain above 126mg/dl, then you might have diabetes.

    Discover yourself. All the best!
