Why Get Tested?

To determine whether or not your blood glucose level is within normal ranges; to screen for, diagnose, and monitor diabetes, and hypoglycaemia (low blood glucose)

When to Get Tested?

If you have symptoms suggesting hyperglycaemia (high blood glucose) or hypoglycemia, or if you are pregnant; if you are diabetic, up to several times a day to monitor glucose levels

Sample Required?

A blood sample taken from a vein in your arm, or for a self check, a drop of blood from your finger. A few diabetic patients may use a continuous glucose monitor which is a small sensor wire inserted beneath the skin of the abdomen that measures blood glucose every five minutes.

Note: In general, it is recommended that you fast 8 hours before having a blood glucose test , however, persons with diabetes glucose levels are often checked both while fasting and after meals to provide the best control of diabetes.
