Hematology and body fluid analysis, refers to use specific automation instruments and reagents to test the collected human samples (blood or body fluid, etc.), analyze the form and quantity of its tangible components (such as blood cells, etc.) and the content of its chemical components (such as proteins, glucose and other biological macromolecules), and then judge diseases or some functions of the human body. It mainly includes: blood analysis, urine analysis, anticoagulation function test and erythrocyte sedimentation rate analysis.

Clinical chemistry refers to use automatic biochemical analyzer to detect a variety of chemical substances (such as glucose, fat, protein, inorganic substances and metabolites, etc.) in human specimens (blood, body fluid, etc.) to diagnose diseases or evaluate the functions and metabolism of various organs of the human body.

Point-of-care testing refers to a test method that is carried out in the field of patient sample collection and rapidly obtains test results by means of portable analytical instruments and supporting reagents. POCT can be defined in two aspects: in terms of space, the test is conducted near the patient, that is, “Bedside Test”; in terms of time, “Real-time Test” can be conducted. The main features of POCT are rapid, easy to use and cost saving, such as blood glucose detection, cardiac markers detection, blood gas analysis, PT-INR detection, etc.

Clinical microbiological testing refers to a testing technology that uses the theory and method of microbiology, and uses specific instruments and reagents to detect and identify pathogenic microorganisms (mainly bacteria and fungi) in human specimens (such as blood, urine, various humors, feces, etc.), determine the type, quantity and nature of microorganisms, etc., and conduct antibiotic drug sensitivity experiments on the identified microorganisms, so as to provide the basis for rational use of antibiotics in clinic.

Analysis of immune function refers to use automatic immunoassay instruments and reagents to detect antigens or antibodies in human specimens (blood, humor, etc.), so as to evaluate the immune function of the body and diagnose disease. It is mainly used for diagnosis and treatment of infectious diseases, malignant tumors, inflammation and autoimmune diseases.
