question about hba1c

[The Balladeer]

hey can the lab result be incorrect yesterday I got my hba1c its 9.6% 4 months ago it was 10.5% even tho I put a good effort trying to bring it down I reduced my carbs intake by alot mostly i eat protein and vegetables I drink so much water i march 30 min everyday I test my bg sometimes up to 10 times a day for the past 3 months it rarely goes above 200 mg/dl ( 11 mmo/l ) most of the time after eat between 140/170 ( 7.8 / 9.5 mmo/l) mg dl and fasting between 85 / 140 mg dl ( 4.7 / 7.8 mmol) should i test again in another lab

does anyone bring it below 8% without using a cgm

I think the lab test results will be reasonably accurate.
You can always use another lab to cross check, for your own peace of mind..
Use https://www.diabetes.co.uk/hba1c-to-blood-sugar-level-converter.html to work out what your average BG should be to give any HbA1c result.

People have gone into remission without using a CGM, which is relatively recent.
[Although as a T1 that isn't an option.]
If you are struggling, though, a CGM is very useful to work out where you may be having peaks which you miss by finger pricks.
You should only need one to give you a good overview of where your BG is going throughout the day.

It might help if you gave a sample daily meal plan.
Sometimes reducing your carbohydrates by a lot still doesn't take you down to low carbohydrate levels.

ty for the response I asked about cgm cause in my country that isn't an option not covered by assurance nor u can buy it out of pocket its unavailable my country thinks its a luxury and not necessary as a matter of fact the health minister never mention or discuss it 2 yes it doesn't bring you to low carb levels but 9.6% ( 12.6 mmol/l eAG ) is a lot compared to the effort still seems something off btw I have very low ferritin level on the test can that make hba1c higher

Definitely!

Influence of Iron Deficiency Anemia on Hemoglobin A1C Levels in Diabetic Individuals with Controlled Plasma Glucose Levels

Introduction: Hemoglobin A1C (HbA1c) reflects patient’s glycemic status over the previous 3 months. Previous studies have reported that iron deficiency may elevate A1C concentrations, independent of glycemia. This study is aimed to analyze the ...

Short version: "In iron deficiency anemia, ferritin is decreased with increase in the red cell life span, and increased red cell life span is associated with increased HbA1c."

In cases like this, where hba1c is likely to be skewed, a fructosamine test can be used instead. It doesn't measure the exact same thing, but it does give you an idea of your average blood glucose over the past few weeks.

I'm also including a useful conversion table for both hba1c in % and mmol/mol, and corresponding BG in mg/dl and mmol/l.
