Preparation guidelines — step by step
Test preparation includes: dietary preparation, discontinuation of medications and supplements, and additional elements — described below. All recommendations must be followed for 24 hours without any deviations. Otherwise the test may yield incorrect results and will need to be repeated at additional cost.
The patient must fast for 12 hours before the test; water is the only permitted fluid. Tests are performed at 8:00 and 12:00. When scheduling the appointment, bear in mind the fasting requirement.
Do not smoke (for at least 12 hours before the scheduled test), including passive smoking — for at least one hour before the test and throughout its entire duration.
Sleep and physical exertion should be avoided for at least 1–2 hours before the test. Intense physical training should be suspended for 24–48 hours. Light physical activity, such as a walk, is permitted before the test. You must remain seated for the entire 3-hour test.
You may brush your teeth and tongue (patients with dentures should not use denture adhesive on the day of the test), but under no circumstances may you swallow toothpaste! If this poses any difficulty, you may proceed with the test without brushing your teeth.
