As long as there is a problem in a certain part of the human body, it is unhealthy. Therefore, no matter blood test, stool test, B-ultrasound, CT, magnetic vibration, etc. It is impossible to find out all the diseases of the body by any examination, because every examination has its pertinence and limitations. The structure of human body is complex, and there are many other tissue structures besides internal organs.
I wish you the best of health!
Hope to adopt, thank you!
