The higher your blood sugar levels, the more hemoglobin you'll have with sugar attached. An A1C level of 6.5% or higher on two separate tests indicates that you have diabetes. An A1C between 5.7 and 6.4 % indicates prediabetes. Below 5.7 is considered normal.
What is GHB testing and why is it important?
GHb testing is being used routinely all around the world to help people with insulin-dependent (type I) diabetes and non-insulin-dependent (type II) diabetes manage their disease. The test has also played an important role in many diabetes research projects, including the recently completed Diabetes Control and Complications Trial (DCCT).
When should the GHB level be measured?
The ADA recommends that the GHb level first be measured at the time of diagnosis and initiation of treatment.
How does GHB affect the body?
GHB acts on the hypothalamus, which is involved in maintaining a number of regulatory functions in the body. One of the consequences of GHB is that the regulatory functions of the hypothalamus regarding body temperature can be disrupted, and individuals can become overheated extremely quickly.
What does it mean when your GHB is 6 percent?
In a person with diabetes, the level is typically higher because of the higher blood glucose levels. How much higher depends on what the person’s average blood glucose level has been. For example, if average blood glucose is 120 milligrams per deciliter (mg/dl), the GHb is about 6 percent.
What is GHb in diabetes?
General Information. Glycohaemoglobin (GHb) is a general term for whole blood glucose complexes that are non-enzymatically bound to alpha and beta chains of human haemoglobin. The most quantitatively prevalent complex is called HbA1C, in which glucose binds to the N-terminus of the alpha chain.

What does a high hemoglobin A1C level mean?
A normal A1C level is below 5.7%, a level of 5.7% to 6.4% indicates prediabetes, and a level of 6.5% or more indicates diabetes. Within the 5.7% to 6.4% prediabetes range, the higher your A1C, the greater your risk is for developing type 2 diabetes.
What is the clinical significance of hyperglycemia?
Hyperglycemia (high blood glucose) means there is too much sugar in the blood because the body lacks enough insulin. Associated with diabetes, hyperglycemia can cause vomiting, excessive hunger and thirst, rapid heartbeat, vision problems and other symptoms. Untreated hyperglycemia can lead to serious health problems.

At what A1C level does damage start?
According to the ADA, A1C level below 5.7 percent is considered normal. An A1C between 5.7 and 6.4 percent signals prediabetes, according to the ADA. Type 2 diabetes is diagnosed when the A1C is at or over 6.5 percent. For many people with type 2 diabetes, the goal is to lower A1C levels to a healthier percentage.
