What diseases can be detected by blood tests

Blood tests are part of routine physical examinations, mainly because the composition of our blood can truly reflect the health of our body. The content of red blood cells, white blood cells and different proteins in the blood corresponds to different aspects of health. For example, red blood cells can be used to determine whether anemia occurs, white blood cells can be used to determine whether inflammation occurs, and other blood sugar and blood lipid levels can also be used.

There are hundreds of commonly used blood tests, which are divided into two categories: one is non-specific indicators. If certain indicators increase or decrease, it can support or exclude the diagnosis of certain diseases. The other is a specific indicator, that is, an increase or decrease (negative or positive) of a certain indicator can diagnose or rule out a certain disease.
