What is Glycohemoglobin?
|
It is a bloodtest that measures the amount of sugar(glucose) bound to hemoglobin. Normally, only a small percentage of hemoglobin in the blood(4-6%) has glucose bound to it.
people with diabetes have more glycohemoglobin(Gly-Hg) than normal. |
|
|
Are there different types of Gly-Hg?
|
Three types, A1a, A1b, A1c are measured in a total Gly-Hg test. test results help monitor the long term control of blood glucose levels in people with diabetes. most experts consider the Gly-Hg A1c level the most effective way to monitor the control of diabetes.

|
|
What is the justification of Gly-Hg measurement?
|
It is useful to get information about the long term control of blood sugar levels. This test requires only one blood sample every 3-4 months, and the test is not affected by recent changes in diet, exercise or medications. Glucose is bound to hemoglobin in RBCs at a steady rate. Since RBCs last 3-4 months, the Gly-Hg level indicates a persons average blood glucose level in the 2-3 months before the test.
|
|
|
The A1c level is directly related to complications from diabetes. TRUE/FALSE
|
TRUE. The lower your A1c level, the lower the risk for complications.
|
|
|
How are Gly-Hg results interpreted?
|
The results reflect the amount of glycohemoglobin divided by the total amount of Hg multiplied by 100(to produce a percentage). Your A1c level may be reported without a total glycohemoglobin level.
|
|
|
What is a normal result?
|
Gly-Hg A1c= 4,5-5,7%
Total Gly-Hg=5,3%-7,5% Severely elevated= 10,5-14 with an average blood glucose mg/ml of 255-360. |
