How do hematology analyzers work
WebAutomated cell counters sample the blood, and quantify, classify, and describe cell populations using both electrical and optical techniques. Electrical analysis involves passing a dilute solution of the blood through … The three main physical technologies used in hematology analyzers are: electrical impedance, flow cytometry, and fluorescent flow cytometry. These are used in combination with chemical reagents that lyse or alter blood cells to extend the measurable parameters. For example, electrical impedance can … See more Manufacturers combine these three technologies with innovative uses of reagents, hydrofluidics, and data analysis tools to produce proprietary methods, each of which has strengths in terms of accuracy, speed, or … See more Your choice of instrument will be driven primarily by the setting of use: patient bedside, consulting room, clinical lab, or research lab.
