You want to control your diabetes as much as possible. You wouldn't be reading this if you didn't. So you regularly check your A1C level. This is the best measurement of our blood glucose control that we have now. It tells us what percentage of our hemoglobin -- the protein in our red blood cells that carry oxygen -- has glucose sticking to it. The less glucose that remains in our bloodstream rather than going to work in the cells that need it the better we feel now and the better our health will continue to be. As we are able to control our diabetes better and better, the reasonable goal is to bring our A1C levels down to normal -- the A1C level that people who don't have diabetes have. But before we can even set that goal, we have to know what the target is. The trouble with setting that target is that different experts tell us that quite different A1C levels are "normal." They tell us that different levels are normal -- but I have never heard of actual studies of normal A1C leve...
I recently saw the following question:
My granddaughter’s HgbA1c was elevated to 10. Her glucose readings have been normal. Why does she have this elevated reading?
It seems obvious at first glance that either the elevated HgbA1c is wrong, or the glucose readings are misleading. I’ll assume that your granddaughter has a diagnosis of diabetes, and that the glucose readings you describe are being done by her with a home glucose meter, rather than being done in a commercial laboratory. You don’t describe her as being a child, teen, or adult, but the issues are mostly age-independent.
As you are aware, the glycosylated hemoglobin test (called by various acronyms including HgbA1c and A1C) has a normal range well below your granddaughter’s value of 10. In people without diabetes, the value is usually about 5; for people with diabetes, most endocrinologists would want to see the value below 7. So, based on her value of 10, one would assum...
HbA1c is a test that measures the amount of glycated hemoglobin in your blood. Your doctor may order this test if you have diabetes.
Glycated hemoglobin; Glycosylated hemoglobin; Hemoglobin - glycosylated; A1C; GHb; Glycohemoglobin; Diabetic control index
How the test is performed
Blood is drawn from a vein. The vein is usually on the inside of your elbow or the back of your hand. A nurse will clean the site for germs. The nurse then wraps an elastic band around the upper arm. This puts pressure on the area and makes the vein swell with blood.
Next, the needle is gently inserted into your vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm. Once the blood has been collected, the needle is removed. Then the area is covered to stop any bleeding.
In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it ble...
