Understand the biochemical basis of the disease and the biochemical changes during the occurrence and development of the disease; When clarifying the principle of biochemical diagnosis of diseases, it emphasizes the discussion of biochemical mechanism of diseases, so it is also called clinical biochemistry. On the other hand, the methods and techniques of clinical biochemical tests are developed and applied to evaluate the data of test results and their clinical value, so as to help the diagnosis of diseases and take appropriate measures.
Appropriate treatment focuses on the application of clinical biochemical laboratory, which is called clinical biochemical laboratory in China.
Its main task is to study the chemical composition and ongoing biochemical processes of human organs, tissues and body fluids, and the effects of diseases and drugs on these processes, so as to provide information and theoretical basis for disease diagnosis, disease monitoring, drug efficacy, prognosis judgment and disease prevention.
