Carb Free Before the Glucose Test?

I have my glucose test coming up and I want to do whatever I need to to get the most accurate results. Should I withhold carbs that day prior to the test. I understand the importance of getting correct results but I don’t want to eat too many carbs and my blood sugar look higher than normal because of the food. I know the drink already has 50g of sugar. So my thought process is that if this is enough to get accurate results, if eating carbs on top of that will make my sugar levels look way too high? Or could withholding carbs make my body “hold on” to the sugar from the drink? I’m not trying to “cheat to pass” but I also don’t want to fail because of my food choice. I just want accurate results.
