With the increase of people’s health awareness and economic development, medical checkup centers are mushrooming, not only in public hospitals of all levels and types, but also in society, such as Aikang Guobin, Ciming, Guokang and so on. Medical checkups also seem to be like buying insurance, sitting in front of the computer, clicking the mouse, choosing white-collar package, celebrity package, noble package, 30 years old package, over 50 years old package and so on. I think this has lost exactly one of the essences of medical checkups, which is the consultation and interaction between the doctor and the person being examined. The human body has 9 major systems (motor system, digestive system, respiratory system, reproductive system, urinary system, endocrine system, vascular system, sensory organs and nervous system), 206 bones, 5 meters long small intestine, it can be said that countless organs can go wrong in every place, there is no one package can cover every aspect of the body. In addition, we have a wide variety of instruments, such as ultrasound, which includes ultrasound of blood vessels of the whole body, ultrasound of major organs from inside to outside, ECG, ambulatory ECG, ambulatory blood pressure, exercise panel, pulmonary function, CT, MRI, PET, gastroscopy, enteroscopy, otoscopy, nasal endoscopy, hysteroscopy, and so on. We also have more and more tests, such as blood sampling to check liver and kidney function, blood lipids, blood sugar, various hormones, tumor markers, allergens and so on. Through urine, we can check for red blood cells, white blood cells, tubular type, bacteria, etc. Through stool, we can check for bleeding, parasites, etc. There are also genomics and proteomics which are very popular recently. We don’t have the time or the need to go through all the tests. It is up to the doctor to decide which tests to do through questioning, physical examination and careful thought.
