Why high HbA1c needs immediate attention?
What is HbA?
HbA is a type of hemogloblin. A well known word “hemoglobin” is a protein present in the red blood cells (RBCs). It is responsible for carrying oxygen to different part of the body. The supply of oxygen helps in nourishing the cells and prevent it from damage. Studies suggests that 90% of the hemoglobin is HbA.
How glucose level relate to HbA?
As every lock has its specific key, this hemoglobin has a specific site for oxygen binding.
When the body’s glucose level increases, which usually occurs in case of a disorder called diabetes milletus; this high number of glucose molecules compete with oxygen to bind with hemoglobin, and occupies its place forming HbA1c (glycated hemoglobin).
As RBCs have a life span of 120 days, HbA1c can give an indication of the body’s glucose level for the last 3-4 months. Thus, enabling a person to keep a track of their glucose level.
High HbA1c- A crying call !
Levels of HbA1c below 6% mg/dL is considered as normal.
The high level relates to improper glycemic control in diabetic patients and warns non-diabetics of developing it.
The elevated levels of HbA1c increases the risk factor for stroke, coronary heart disease, organ dysfunction and damage to the nervous system.
Studies suggests that lowering the level of HbA1c reduces the risk of most complications related to diabetes.
Why is HbA1c test important?
It is currently the best way to check whether a person has diabetes or for monitoring the blood sugar levels in diabetics.
This test helps doctors to predict the effectiveness of the insulin treatment.
The cherry on the cake about this testing is that it does not need fasting to get accurate results.
Another advantage it offers is that it can be done immediately at a single visit and can reveals about diabetes and its control.
Above all it is accepted world wide as a gold standard test.
