What physical examination items does the multifunctional home physical examination instrument generally include?

The general physical examination instrument has only one function. If it is multifunctional, it generally has three functions, blood sugar measurement, blood pressure measurement and ECG measurement. With the development of medical treatment and science and technology, there are more functional home physical examination instruments, which can detect more items besides the three functions mentioned above. You can also measure blood oxygen and body fat, and some of them are smart, and you can also ask for medicine online. I recently came into contact with a functional home physical examination instrument "elf", which has these functions and other entertainment functions, and is very practical.
