I found a website that listed drugs that can affect blood glucose levels:

I didn't see Lorazepam or Ativan listed here.
Yes
When I had a glucose tolerance test during pregnancy I was told to fast from midnight the night before, I was told to only drink water and nothing else, hope that helps!
Blood samples are taken from a vein before and after a patient drinks a thick, sweet syrup of glucose and other sugars
Only your doctor can advise you of whether you should take or skip your antidepressant anti-anxiety meds before a glucose tolerance test. You have to fast for eight hours prior to the test so it has to be done early in the morning. You can always just hold off on the medication until the test is finished.
There are many factors that influence this. They include what you have eaten the night before, how you are feeling that day, and how you react to the drink.
4 mg Lorazepam
Yes it will affect the reading you get (not your actual blood glucose). If you have food (especially sugary food) on your finger where you take the drop of blood from, then the sugar from the food will mix with the blood and give a false reading. This is why it is important to wash the finger before testing blood glucose.
To make the results all the same for different people. If you have eaten food prior to the test, the results will be different - actually fasting before the test might avoid any false result. because when we are fasting the glucose supply will be cut and so, this will not interfere with the glucose loaded during the experiment. because what we want to observe is how the body will react with that particular amount of glucose intake in the given time.
Water. Anything else will affect the glucose levels...including black coffee.
Normally the blood sugar levels is lower before the drink, rises quickly during the first few hours, and slowly drops again.
There are several blood tests that can diagnose diabetes. The most common is a fasting blood glucose test, where the glucose level is measured after at least eight hours of fasting. The blood glucose can be measured without fasting, but it can only diagnose diabetes, not prediabetes. The oral glucose tolerance test monitors how a body responds to an influx of glucose. After fasting for a least 8 hours, blood glucose levels are measured before and every 30-60 minutes after the ingestion of a glucose beverage for three hours. A urine test for high levels of glucose and ketones can help diagnose diabetes, but these results are not enough on their own.
After eating, glucose is greater in the hepatic portal vein than in the hepatic vein . Hepatic vein contain more glucose before eating, because the stomach is empty .
