A fasting Glucose test measures the glucose levels in the blood, commonly known as blood sugar. Glucose is one of the main sources of energy in your body. A hormone called insulin helps to transport glucose from your bloodstream into your cells.
The sugar level in your body needs to be in a range to regulate the activity of the different body parts. Increased or decreased amounts of glucose in your blood can cause severe medical conditions. High blood glucose levels, commonly known as hyperglycemia, may be a sign of diabetes, a chronic health condition that can cause serious problems.
Low glucose levels, known as hypoglycemia, are common in people with type 1 and type 2 diabetes. Certain conditions, like liver disease, may cause low levels of blood glucose, but that is in some rare cases. However, without treatment, severely low blood sugar can lead to health conditions, including seizures and brain damage.
There are many tests available for checking if your blood glucose is at a normal level. Some of them are blood sugar fasting tests, fasting blood glucose, fasting plasma glucose, etc.
