What are hematology analyzers?
Hematological analyzers are computer, highly specialized and automated machines that calculate the number of different types of white and red blood cells in a blood sample. The results they provide are jointly known as a complete blood number (CBC) or a complete blood number with cell differentiation (CBC with Diff). Most of the current hematology analyzers provide the number of red blood cells (RBC), hemoglobin in RBC, hematocrit levels, number of plates, corpuscular data and the number of five different types of white blood cells. Some newer machines also measure the number of two specialized cell types - immature white cells and nucleat red blood cells - which are necessary to confirm specific diagnoses. Before this time, the numbers of cells were manually performed. The laboratory technician sat on the stool and looked at the sesides marked with a microscope grid and calculates cells using the hand counter. Needless to say, no number of two cells were the same and the numbers could also vary according to the preparation of the image or what part of the sampleBlood was applied to the examined image. Automated Hematology analyzers have greatly reduced this type of variability.
Hematological analyzers count cells one of three general cellular flow cytometric techniques: electrical impedance method, light scattering or use of fluorescent dyes to distinguish cells. Cell cytometry refers to the ability of a hematological analyzer to classify one cell based on its specific size or shape or its biochemical or antigen composition. The size or shape of the blood cells can be determined either according to the degree of electrical impedance it causes or the type of light dispersion that demonstrates the might. Biochemical or antigenic properties are usually classified using fluorescent dyes. The final result of the laboratory of a complete blood point of view is the result of a blood sample of the cells examined by the cell, PThe blood is directed through the Inquiry Chamber.
among many remarkable advances in medical science in the last few decades hematological analyzers have a quietly revolutionized medical practice. Internal medicine, pediatrics and oncology are many specialties of medicine that require frequent, current and accurate CBC tests to see if treatment is effective. It is now taken for granted that CBC tests can be ordered, blood collected and results available within an hour with analyzer devices.
