Diabetes (HBA1C) Test
Diabetes is a lifelong condition that causes a person's blood sugar level to become too high.
There are two main types of diabetes:
- type 1 diabetes – where the body's immune system attacks and destroys the cells that produce insulin
- type 2 diabetes – where the body doesn't produce enough insulin, or the body's cells don't react to insulin
Type 2 diabetes is far more common than type 1. In the UK, around 90% of all adults with diabetes have type 2.
During pregnancy, some women have such high levels of blood glucose that their body is unable to produce enough insulin to absorb it all. This is known as gestational diabetes.
HbA1c levels are considered to be a good measure of your 90-day glucose levels and do not vary as much day-to-day as your standard glucose marker.
High HbA1c levels are widely considered to be indicative that you either have, or have an elevated risk for developing, type 1 or type 2 diabetes. If already diagnosed, HbA1c can also be a good indicator on how well your diabetes treatment plans are working.
It's very important for diabetes to be diagnosed as early as possible because it will get progressively worse if left untreated.
