How much is it reasonable to buy a physical examination for parents?

First of all, the physical examination items for parents should be comprehensive enough. Secondly, the price should not be too expensive. In addition to basic internal medicine, surgery, blood routine, liver and kidney function, X-ray chest film, etc. It is best to have tumor markers, multi-organ color Doppler ultrasound and reproductive organs. If organ cancer occurs, it can be found and treated early through physical examination, and the price is almost 2000-3000 yuan. For your reference, I bought a beautiful and healthy sunset red package for my parents, which was in early 2000. Besides the above items, there are three items: myocardial enzymes (for acute myocardial infarction), Helicobacter pylori, bone mineral density detection, arteriosclerosis detection and so on. I think the physical examination items set by professional physical examination institutions must have been professionally considered. I recommend you to have a look. Now you should know how much a physical examination costs.
