Erythrocyte Image System

A: White blood cell count, red blood cell count, haemoglobin count, platelet count, lymphocyte percentage, monocyte percentage, granulocyte percentage, and other parameters can be determined with a hematology analyzer which is widely used. As a result, the hematology analyzer can currently be found in a variety of clinical settings. Because of the other factors that can be determined and analyzed in conjunction with blood cells, the hematology analyzer is also known as a haematology analyzer.
Instrumental analysis has numerous advantages, such as quick analysis, many parameters, cheap labor effort, consistent results, and so on, but it also has certain disadvantages. Instrumental analysis minimizes the perceived subjective factor and eliminates the impacts of perception to some extent, but it also rejects man's subjective initiative and so necessitates a review, particularly for cell morphology and classification, if there are questionable results during the test.
In practice, the hematology analyzer discovered that the size of mature red blood cell volume, and its morphological observation is the same as hematology analyzer determination. For abnormal changes in red blood cell morphology, the hematology analyzer can only suggest shadow red blood cells, but not other heterogeneous red blood cell morphology. As a result, the hematology analyzer has trouble recognizing the cell morphology of a lymphocyte. All classifications show an increased monocyte ratio and hematology analyzer is unable to distinguish between naive cells, heterogeneous lymphocytes, nucleated red blood cells, and toxic granules. Instrumental analysis is difficult to deliver a completely correct analysis since it only depends on the identification of a few physical features of the cells. As a result, manual cytomorphological examination of abnormal blood images should be performed and incorporated into the laboratory department's daily quality control to continuously improve the testing staff's comprehensive quality, reduce missed diagnoses and misdiagnoses, and provide a scientific basis for clinical diagnosis, treatment, and further examination.
The blood smear is the first window into blood analysis and disease diagnosis, and the information provided is unmet by the hematological analyzer in many ways. It not only is cheap and clear, but also offers the basic data provided by the hematology analyzer. It can now provide more complete and thorough information on a wide variety of features of blood, thanks to further study into blood smears. Blood smears are useful for the direct examination of human parasites, the study and testing of blood-borne infectious diseases, the detection of anemia, the diagnosis of abnormalities in leucocytes and platelets, and the microscopic examination of blood smears, especially when the data provided by the hematology analyzer is abnormal.
In conclusion, both traditional blood smear microscopy and modern hematology analyzers are useful for blood analysis and illness diagnosis. As a result, each laboratory should create its own rechecking circumstances, train its testing staff to these uniform standards, and conduct quality control. Only by constantly expanding knowledge and practical abilities via experimentation and practice can the hematological analyzer and the blood smear be made more scientifically useful.

A: The Hematology analyzer is a common tool in the laboratory, and it is also a basic clinical laboratory tool. In the process of using the instrument, cleaning is the most important thing to do in the maintenance of the instrument, so how can the Hematology analyzer be cleaned more thoroughly?　
When cleaning the Hematology analyzer, it must be cleaned every day, and the cleaning agent must be used well. The role of the cleaning agent is to remove the protein and debris from the small holes and pipes. The first cleaning job is flushing: press the FUNC key, select perfusion, and the instrument will automatically perform perfusion and flushing. Then turn off and perfusion: this procedure must be executed when the instrument is turned off after the work is completed to fill the probe cup with the cleaning solution.
If the effect of the cleaning agent is not good, it will not play its due role, and it will inevitably cause blockage after a long time. These cleaning agents are often used after each specimen is tested. If the physical and chemical indicators are too high, it will cause foam or other components of the cleaning agent. If it is not cleaned, it will affect the counting. The physical and chemical indicators are too low and the effect will not be achieved. This is the reason why the cleaning agent is second only to the complexity of the diluent. Domestic reagents are often imitated, and few people do basic verification and evidence analysis. .
In addition to the internal cleaning of the instrument, the appearance of the instrument should also be well maintained. The surface stains of the instrument, especially the blood sample splashes that may remain around the sampling needle, must be treated every week to prevent protein deposition, mildew and Pollution.
Cleaning agent is an indispensable reagent for the use of blood cell analyzer. Long-term use of poor quality cleaning agent will cause discoloration, hardening, and blockage of water system pipes, which will cause changes in liquid flow rate and pressure, drift of detection results, and system errors Larger, the hole blocking rate increases. The correct method of use is to clean every day after the test is completed, and to clean the instrument weekly and monthly, so as to make the test results more accurate.
