The Day Before Your Exam
For breakfast and lunch only, eat a light meal (plain rice porridge with soy sauce, white rice with broth, or castella/sponge cake with milk). After that, drink plenty of water to prevent low blood sugar and dehydration.
Please follow these precautions carefully to ensure an accurate exam. Repeat exams due to inadequate preparation will be at the patient's own expense.
Self-Check
Thoroughly emptying your bowels is essential for an accurate exam.
Even if your stool appears clear, please finish drinking the entire bowel-prep solution.
