The laboratory examination is a discipline that includes clinicians detect specimens through clinical laboratory tests to obtain relevant information as needed, and to analyze overall disease in combination with other clinical information to complete the screening, diagnosis, evaluation severity, formulation of prevention and treatment measures, Promethation Judgment and Assessment of Human Health. at The Techniques that Commonly Used in Clinical Laboratories Related to at The Fields of Physics, Chemistry, Biology, Biochemistry, Immunology, Molecular Biology, and Cytogenetics. Specimens Commonly the include Human Blood, Bone marrow, secretions , excretions, Tissue Cells and other body fluids, etc.
Various known specimens that have been proved to be relevant for detection or disease-related in vivo can be used for testing, and for examination of most diseases in the whole body. The abnormal results may indicate that the disease at the source of the specimen or The alteration caused by other diseases in other tissues or organs. For example, abnormal detection of RBC, WBC, and PLT in hematological examination may indicate hematopoietic diseases of primary hematopoietic tissue or hematological changes caused by other non-hematopoietic diseases. a combination of clinical Some tests can provide support for diagnosis, such as pathogen detection by etiological examination.
The dynamic monitoring of certain indicators through laboratory tests can evaluate the therapeutic effects, and some indicators also have a certain predictive effect on the prognosis. Through screening, diseases can Be found early and its prevention can be achieved. The results of laboratory tests can also Provided accurate data for medical scientific research. With the advancement of scientific research, it promotes the progress of laboratory diagnosis.
