Does what you eat the day before affect glucose test?

Will what I eat affect my glucose test?
The micronutrient, carbohydrate, protein, and fat levels in your food can all skew the results of some tests.

Eating foods high in carbohydrates can significantly raise your blood sugar levels within 15 minutes.
Does what you eat the night before affect blood work?

Can I refuse the glucose test when pregnant?

Is it easy to fail the 1 hour glucose test?
Odds of passing
The truth about this test is that the one-hour test is pretty easy to “fail,” and many people do! They make the threshold low enough so that they catch anyone who could be having an issue, just in case. The levels on the three-hour test are much more reasonable and easier to meet.
What is the normal blood sugar level for a pregnant woman?
Target Blood Sugar Levels for Women During Pregnancy

What should a 12 hour fasting blood sugar be?
After a fast of 8 to 12 hours, your blood is drawn to measure the blood glucose level. A blood glucose level measuring below 6 mmol/L (100 mg/dL) is normal. If your blood glucose level is between 6.0 and 6.9 mmol/L (100 mg/dL and 125 mg/dL), you have prediabetes (impaired fasting glucose).
Can I exercise the night before a blood test?
