In brief: GTT at home
Glucose tolerance testing is done less frequently now a days.
You can do your own home version geta home glucose testing kit. Do the 1st blood glucose after an overnight fast, have a very hearty breakfast and do a bl glucose 1 hour and 2 hrs after the breakfast. Your fasting bl glucose should be below 200 if above 200 you do not need to do the test, you have diabetes and the result will not cha.

In brief: 2-hr OGTT
Patients are asked to fast 8-12 hours before the test.
Some places can put in a little IV so that blood draws can come from it instead of repeated needles. The first sample or two of blood are about 15 min apart. Then you will get a very sweet drink. Blood will be drawn 30, 60, 120 min (sometimes more frequently) afterward for glucose to see how yor body responds to the sugar drink.
