Go to see your doctor and discuss in detail, also further evaluation for your low white cell and prescription of vitamin d. ...Read more

What can cause a high hemoglobin A1c test?

What can cause a high hemoglobin A1c test?

Poor sugar control: Hemoglobin A1c measures average blood sugar over approximately the past 3 months. It is the measure of how much hemoglobin is attached to sugar molecules in the blood. Sugar in your blood binds to the hemoglobin of the red blood cell and stays there throughout the cell's lifetime (120 days). At high levels of blood sugar, more reacts w/ the hemoglobin, causing an elevated hemoglobin a1c. ...Read more

Do you fast for a hemoglobin A1c test?

Do you fast for a hemoglobin A1c test?

Short answer: The test measures indirectly measures glucose control over the preceding 6-8 weeks. It does not measure sugar directly; therefore I would believe it not to be necessary to fast prior to the test. However, the best way to answer this question is to call the lab where you go to have the blood drawn and ask them directly whether you need to fast for the test. ...Read more
