HOW IS PRE-DIABETES DIAGNOSED?

By testing your BGLs. There are two blood tests that can be used:

• A fasting blood glucose or a non-fasting random blood

glucose Blood is taken from a vein in your arm. This test may be done fasting (nil by mouth for at least eight hours) or non-fasting. If your BGLS are above the normal range (but not high enough to be diagnosed as diabetes) you will need further testing.

• An oral glucose tolerance

test (OGTT) You’ll have a fasting blood glucose test first. You’ll then be given a sugary drink and have your blood checked again two hours later. The results from the OGTT will show whether your BGLs are in the normal, pre-diabetes or diabetes range. If you have pre-diabetes, you’ll have one or both of these conditions: • Impaired fasting glucose: When your fasting BGL is higher than normal, but not high enough to be diagnosed as diabetes.

• Impaired glucose tolerance: When your BGL is higher than normal two hours after an OGTT, but not high enough to be diagnosed as diabetes. Your fasting BGL may still be in the normal range.
