How to Test Your Blood Sugar Using a Fasting Glucose Test

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.

What are the Steps for the Blood Sugar Test?

There are many ways to test your blood glucose level. You need to consult with your doctor, and they will prescribe you the type according to your symptoms and other conditions. But if they suggest you take a blood sugar fasting test, then you need to do some preparation before taking it.

  • If you have already been diagnosed with blood sugar, you may be asked to stop your morning dose of insulin or diabetes medicine.

What are the Various Blood Glucose Ranges?

You need to know about the three main ranges to determine if you have diabetes.

  • The normal range of blood glucose is 99mg/l or lower. You are in a safe zone if you see the number on your report lower than 99mg/dL. 
  • If the number falls between 100-125mg/dL, you may have a chance of having diabetes and need to control your diet. This range means you do not have diabetes yet, but you may be if you continue with your lifestyle.
