My husband is to have a 2 hour glucose tolerance test on Thursday. What preparation should he have. I have googled it and am totally confused. Specifically, what should he avoid in order to have a good result. Should he do the low carb diet for 3 days before or eat normal. I find several answers each way. Does smoking affect his results? What about coffee? He is concerned about having a false positive result.
Thanks in advance.
Your husband should not be concerned about a false positive test result. The point of the test is not to fake a pass. The point of the test is to help you - to diagnose a disease that can lead to several devestating side effects if its left undiagnosed (e.g. blindness, amputation, heart attack, etc.). If its diagnosed, your husband can take steps to control it and live a healthy life. Of course if he tests negative, all the better.
You're supposed eat, drink, do everything as you normally do. I believe you stop eating at midnight the night before, and then go in that morning. Tell your husband to take a good book to read with him since he'll be there for a while.
Thanks. I'm sure you are right, but he has read about the incidences of false positive tests and just wants to avoid that if possible.
It's better to have a false positive than to fake a pass. A false positive would entail eating better food, and living a healthier lifestyle through more exercise, while a faked negative would leave him with unchecked high blood sugar and the accompanying damage.
