Observing the pathological changes of cell morphology through a microscope, providing a basis for disease diagnosis, is the gold standard in the diagnosis of various diseases.
At present, the blood cell count has been freed from the traditional manual operation and microscopic examination, and can be completed by an automatic blood analyzer. Although the blood cell analyzer has been popularized, it has played a significant role in the actual work: improving work efficiency and quality, and providing more scientific parameters for clinical testing.
However, the blood cell analyzer does not have the ability to recognize the morphology of red blood cells, white blood cells, and platelets, and it is not completely possible to replace the microscopic identification and classification of blood cells.
If you rely solely on the test results of the instrument, without analysis and review, a certain number of error reports will be generated, which may lead to misdiagnosis or unreasonable treatment. Blood cell morphology test is still an important item in the basic diagnosis of blood diseases and routine hematology tests, and it is the most basic, simple and practical test method. The quality of blood cell morphology test is the key to the prevention, diagnosis, differential diagnosis and post-mortem judgment of many diseases, especially blood diseases. Blood cell morphology tests include basic knowledge and clinical experience of erythrocyte, white blood cells, platelets, and other abnormal cell morphology. When the disease occurs in the body, the number and morphology of the cells change. Due to the widespread use and abuse of antibiotics, when the disease occurs in the body, the number of cells often does not change significantly. The morphological test can reflect the changes of the disease. Neglect.
The difficulty of examining blood cell morphological changes under the microscope by manual operation is:
( 1 ) Inefficient . Manual operation is inefficient, cumbersome and has a huge workload;
( 2 ) Poor precision . The inspection results are affected by the random error of the operation process, the systematic error of the experimental equipment and the inherent error of the detection method, and it is difficult to ensure the accuracy; the unified standard inspection method and inspection conditions are the premise for the quality control of the inspection, but currently used by the laboratories. The quality of instruments, reagents, methods and inspectors are different. The test results are often subjective and one-sided. The results of each laboratory are difficult to recognize each other, which has a negative impact on clinical diagnosis and treatment. In addition, blood cell morphology tests do not have a quantitative standard control for indoor and inter-room quality control as biochemical tests. Therefore, the overall quality management of blood cell testing is very necessary.
( 3 ) High requirements for the testing physician . Blood cells (including white blood cells, red blood cells, and platelets) are numerous in variety and form, and are prone to mutations; they require considerable experience from the testing physician. In addition, cell morphology changes do not occur in isolation, and are related to the patient's signs, clinical manifestations, family history, and genetic history. The inspectors should have a high ability to combine clinical symptoms, signs, and test results for comprehensive analysis.
Compared with manual microscopy, the MEDICAEasyCell Blood Cell Morphology Analyzer has the following advantages:
( 1 ) Improve efficiency
( 2 ) Reduce the work intensity of doctors
( 3 ) Quantitative analysis
( 4 ) Remote diagnosis
( 5 ) Facilitate expert consultation
( 6 ) Easy for patients to understand the test results
( 7 ) Easy to retain image files
( 8 ) Making massive screening possible
( 9 ) Convenient research and teaching
( 10 ) Improve the informationization of hospital blood routine examination
The significance of blood cell morphology examination
The blood is generally easy to test and easy to detect. It is still the primary procedure for screening diseases and selecting other experimental tests. Blood cell counts and blood morphological examinations are the most basic and commonly used tests in blood testing programs. Blood cell morphology test is the basis and core of laboratory medicine, and is an important means of disease diagnosis.
In the field of blood routine morphological examination, the contradiction between supply and demand of medical resources is prominent, and there is an urgent need for an automatic image analysis system that can replace artificial microscopy.
