What is hemoglobin a1c?

What is hemoglobin a1c?

Average blood sugar: Hemoglobin A1c is a measure of the percentage of red blood cells permanently bound to glucose. Normally about 5% of our red cells are glycosolated. If you have greater than 6.5% you are diabetic. It is not affected by fasting, and since our rbc's live 90-120 days, it reflects an average over that time.

Hemoglobin A1c level is 8.4--is this safe?

Diabetes.: A HgbA1C of 8.4 suggests you have diabetes which is not well controlled, and therefore you are at risk for long-term diabetic complications. It needs to be lowered, ideally below 6.5%

Have white cellscount 3.7th/ul, eosinophils 7ng/ml, vit d 19ng/ml and hemoglobin A1c 5.8%. What means? What happened with my health? Please answer me!

Blood work: The best way is for you to discuss with the doctor who ordered the test. Anyway, the interpretation will depend on the normal range used at the lab where you had the tests done. In general, here, your white blood cell is mildly low, and you are deficient in vitamin d. Go to see your doctor and discuss in detail, also further evaluation for your low white cell and prescription of vitamin d.

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.

Looking for hemoglobin A1c advice?

Hemoglobin A1C: This is a rough estimate of average blood sugar control over a three month period, more accurate than a single fasting blood glucose (sugar) level. In many tests, greater than 5.9 is considered abnormal, but you should discuss risk factors and prevention of diabetes with your doctor.

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.
