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

No: The hemoglobin A1c is a measure of the amount of hemoglobin that is bound to glucose (blood sugar) in red blood cells.

No alcohol problem.had blood tests done 2days after an evening out. so want to know how to get the level in blood down before CDT test ?

No alcohol problem.had blood tests done 2days  after an evening out. so want to know how to get the level in blood down before CDT test ?

Complicated issue: CDT is not likely to be abnormal from drinking one day. It is a marker for chronic alcohol use. If you have been drinking over the past two weeks, CDT may be abnormal and there is not way for you to affect the results now. Alcohol never did any body any good, so stay away from it. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more
