I am a 5 1 year-old male. After sub-health "a drop of blood detector" detection, there are many grains like rice grains. What is that phenomenon? What are the disadvantages?

This is a lie. I am only 24 years old. Tests show that I have cholesterol crystals, rheumatism and seven or eight problems in my blood. Also said to pay attention. A five-year-old child died of a cerebral hemorrhage the other day. Let me buy him medicine to expel cholesterol. You know cholesterol is also needed by the human body. As long as it doesn't exceed the standard, it can keep healthy. Those who claim that a drop of blood can check all diseases have little medical knowledge. If you have any questions about your health, you'd better go to a regular hospital for examination.
