The physical examination usually starts at 8:00 a.m. and is usually conducted in the morning from Monday to Friday, and the afternoon is the time to explain the report. It is usually necessary to make an appointment for the physical examination, so that you can clarify the items of the physical examination and know the relevant precautions. Before the physical examination, you should make preparations, for example, in the first few days before the physical examination, pay attention to a light diet, do not eat foods high in fat, purine, protein and carbohydrates, so as not to affect the results of blood glucose, lipids and uric acid tests. In addition, do not exercise strenuously, and try not to eat animal blood products a few days before the physical examination, so as not to affect the results of the fecal occult blood test.
