What Is A High A1c

Understanding Your A1c

The A1C is a blood test that helps determine if your diabetes management plan is working well. (Both Type 1 and Type 2 take this test.) It’s done every 2-3 months to find out what your average blood sugar has been. (You may also hear this test called glycosylated hemoglobin, glycohemoglobin, hemoglobin A1c, and HbA1c.) A1c is the most common name for it though. How the test works Essentially, the test can tell how much sugar is in the blood stream by looking for proteins (hemoglobins). When glucose (sugar) enters the blood, it binds to the protein in the red blood cells. This binding creates “glycated hemoglobin”. The more sugar in the blood, the more glycated hemoglobin. It’s important to test your blood sugar levels (BGLs) throughout the day; however, an A1C test gives you a bigger picture with a long-term average of those blood sugar levels. What do these numbers mean? The A1c is an average of what your blood sugar levels have been over the 3-month period. In general, the higher your A1C number, the higher your likelihood of diabetes complications. (You don’t want a high A1C; it means there is too much sugar in your blood and your body isn’t absorbing it.) A1C number Continue reading >>

    I recently had my HbA1c test and it has gone up from 6% to 9% my doctor has now doubled my metformin and said it wasn't too bad, just a little blip. I am wondering if he is correct as it sounds like a big jump to me. Is a HbA1c of 9% that high?

    I would say that's bad as it puts you up towards the amber section of the HbA1c levels as can be seen on this link just enter your values in the converter http://www.diabetes.co.uk/hba1c-units-converter.html
    A few months ago I had 7.5 % HbA1c results and my BS levels when I tested myself were in the teens to the 20.s. Do you have a meter to test yourself, if not I would ring one of the meter companies like Bayer, Abbott Medisense, Life Scan, or Accu Chek etc as they will more than likely send you one free.
    These meters generally come with 10 strips to start you off, then approach your gp to get test strips, but this can be a post code lottery as if they will provide strips on prescription. You have a good reason to ask for strips as you need to find outs what food etc is causing the highs.

    Hi. An Hba1ic of 9.0% isn't good and I can't understand why the GP said it's a blip. By definition the HBa1c is a 3 month average; hardly a blip. That HBa1C level needs action as NICE Pathways give 7.5% as the level to stay below and the Metformin increase will have little effect. Are you on a low-carb diet? If not then adjust your diet to have, say, a max of 150gm/day of carbs. How old are you and what has the HBa1C trend been since diagnosis. If you are not overweight and quite young then let us know as your diabetes type diagnosis may need to be reviewed.
