What are the three items of routine physical examination

One type is the core three items in the general basic physical examination, which are the default "three routines" in clinical practice - blood routine, urine routine, and stool routine; the other type is the simplified three items in special screening scenarios such as employment, school enrollment, and health certificate application. The common combination is blood pressure, blood routine, and chest X-ray. In some areas, it will be adjusted to targeted items such as liver function and infectious disease screening according to needs.

A while ago, I helped my cousin who had just graduated to handle the physical examination before she started working. She checked the guide in advance and thought she should do a regular bowel movement. She drank a lot of warm honey water in advance to promote bowel movement. She squatted for more than 20 minutes at the physical examination center to hold in the sample. When she submitted it, the guide said that the three items required by her company did not include a regular bowel movement at all. She wasted a long time and made a big joke.

Speaking of which, why do clinical practices regard the three routines of blood, urine, and stool as the core items of a general physical examination? In fact, the core is that the price-performance ratio is high enough, and you can take a basic "full-body snapshot" of your body for a very small amount of money. Take a blood routine as an example. A tube of fingertip blood or venous blood can tell whether you have recent bacterial or viral infections, whether you have anemia, or whether you have abnormalities in your coagulation function. I used to have a friend who often stayed up late and didn't feel any discomfort at all. However, the annual physical examination showed that the platelet count was much lower than the normal value. Further investigation revealed that it was early immune thrombocytopenia. After intervention for more than half a year, it has returned to normal. If I hadn't done this test and delayed going to the hospital until bleeding, I would have been in big trouble. Routine urination is more convenient. By collecting urine in the middle, you can see the metabolism of the kidneys, whether there are urinary system infections, and even early detection of signs of diabetes and nephritis. Many people think it is dirty and do not want to do it. In fact, it is a pity if it leaks. As for the stool routine that many people despise the most, it is actually the most economical and non-invasive way to screen for gastrointestinal bleeding, intestinal inflammation and even early-stage colorectal cancer. Just take a small sample to detect occult blood in the digestive tract that you cannot see. Many early-stage colorectal cancers are screened out through this project. There is really no need to abandon the test out of embarrassment.

Nowadays, many people have different definitions of the "three items of routine physical examination". For example, some private medical examination institutions will refer to blood pressure, blood sugar, and blood lipids as three high screening items. In other infectious disease screening scenarios, screening for hepatitis B, syphilis, and AIDS will be called preoperative or employment three items. There have been many misunderstandings in the absence of unified standards. If you really encounter a requirement to do "three routine physical examinations", it is best to ask clearly about the corresponding scenarios and specific items in advance, so as not to make a wasted trip and avoid missing items and delaying things.
