Do I have to fast for a hba1c blood test?

Do I have to fast for a hba1c blood test?

Not really: The aic test generally tells us what has been going on with your sugar over the past 3 months approximately. One does not really have to fast for it, but it is best done fasting in my opinion, because your doctor will probably want to see a fasting blood sugar at the same time to help manage your diabetes. Often a lipid panel is done at the same time, which requires one to be fasting. ...Read more

Not to worry...: These values are within the expected range, so i see no need to worry about them. If you are concerned about possibly having diabetes, due to family history, then i would suggest you see your primary care physician to discuss these concerns. ...Read more

Need help docs! my blood test showed a hba1c level of 6 (the maximum range level is 5.7). How concerned should I be and what dietary changes should I make?

Need help docs! my blood test showed a hba1c level of 6 (the maximum range level is 5.7). How concerned should I be and what dietary changes should I make?

6 is still good: A Hba1c of 6 is still good. You should be mildly concerned but determined to make significant lifestyle changes to lose weight, increase exercise. Now is the best time to do this, before the effects of diabetes set in making it harder to lose weight. Right now your body is just a 'little' off and resetting it will be easier than when it is 'way' off! ...Read more

What can I do to lower my HbA1C and glucose levels? My last blood test over a year ago shower HbA1C 5.6 and glucose 83.... I still eat lots of sugar!!

What can I do to lower my HbA1C and glucose levels? My last blood test over a year ago shower HbA1C 5.6 and glucose 83.... I still eat lots of sugar!!

What's the concern?: Eating sugar isn't really a factor when blood glucose is being evaluated. Maybe you can get your carbs in some other more wholesome form. Both your HgbA1c and glucose are fine. At age 24, you've got lots more worth your attention than fretting over labs. The key to preventing diabetes long-run -- and a huge help to one's emotions in a cruel world -- is staying aerobically fit. Best wishes. ...Read more

Find another cause: Make a conscious decision to stop the obsessive idea that you have diabetes. If your personal physician cannot find the cause of your symptoms, get a consult. If you want to tell us what symptoms / signs you're having, i bet the healthtap team can suggest a few ideas -- including some that are often missed. ...Read more

My father is 55 year old . His blood test result of hba1c is 7.6%. And urine microalbumin level 85 mg/l . Is it normal? ? If not so how to control it.

High HbA1c : Your father has two problems. One is poorly controlled diabetes and the other is proteinuria. (p). P has ominous implications. Patients with significant p have an increased incidence of renal failure, stroke and cardiac disease. Have a nephrologist collect his urine to see how much protein is in it/day. He will need to be on ace-i or arb's to lower it. Have his glucose controlled so his hb1ac. ...Read more

Can eating before a hemoglobin A1c blood test make the levels higher than they really are?

Can eating before a hemoglobin A1c blood test make the levels higher than they really are?

No: Hemoglobin A1c is a test used to measure the sugar content in your blood that has occurred over the last few months. By eating before a blood sugar test (usually done by finger prick) you can elevate the sugar levels in your blood, but this won't immediately change your hba1c. Hba1c comes from a build-up of "glycated hemoglobin" in the red blood cells over their life cycles, about 120 days. ...Read more
