Medical testing is the use of modern physical and chemical methods, means of medical diagnosis of a discipline, the main study of how to provide the basis for clinical diagnosis and treatment through laboratory technology, medical equipment. Through systematic study, we will understand how to identify the human blood type, to determine whether a person is anemic, liver function is normal and so on. The discipline requires the use of a variety of photoelectric instruments and chemical reagents to complete the experimental analysis, so it favors science and requires a good foundation in biology and chemistry.
Clinical testing is the patient's blood, body fluids, secretions, excretions and exudates and other specimens, through visual observation, physical, chemical, instrumental or molecular biology methods of detection, and emphasizes the whole process of testing (pre-analysis, analysis, post-analysis) to take strict quality management measures to ensure the quality of testing; thus, for the clinic, for the patient to provide valuable experimental information. Clinical testing is a multidisciplinary interpenetration, cross-fertilization of integrated applications involving chemistry, physics, biology, biochemistry, immunology, microbiology, physiology, pathology, genetics, molecular biology, statistics, and a variety of clinical medicine and other disciplines.
