Gucose Tolerance Test Information

glucometerWhat is a glucose tolerance test?

A glucose tolerance test is a test for diabetes.  Diabetes is a disease in which the body cannot control the level of glucose (sugar) in the blood properly.  In some people diabetes develops very quickly over a period of days or weeks.  These people have high blood glucose levels and are diagnosed without them having to have a glucose tolerance test.

Many people with diabetes develop symptoms very slowly.  Blood glucose levels are not usually very high in these patients and to make a diagnosis it may be necessary to carry out a glucose tolerance test.  It is important to diagnose all forms of diabetes to prevent possible complications.  If the glucose tolerance test shows diabetes, the treatment usually consists of alterations to the diet.  Treatment with tablets may also be needed.

What does the test involve?

It is important that you fast from midnight before the test.  This means nothing to eat or drink before the test except water and any medicines you have been prescribed.

The test involves the collection of two small blood samples.  The first sample is fasting blood to measure your baseline blood glucose.  Next you will then be given a glucose drink containing a known amount of glucose.  You will then be asked to wait for two hours.  It is important during this time that you rest and do not eat or smoke.  You may drink water.  At two hours a second blood sample will be collected.  This second sample allows to measure how well your body has coped with the glucose load.  You can then leave.
