WebMay 30, 2013 · Analyzers are highly automated to maximize throughput, to improve user safety from biohazards, and to diminish the risk of cross-contamination. Samples are loaded into the machine and tests are programmed by the user. A probe measures an aliquot of sample and places it into a reaction vessel. Reagents are added from an on-board … 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. Note that instruments must have regulatory approval for clinical as opposed to research … See more Time per analysis depends on the parameters being measured. The rate limiting step is the reaction time for reagents. A simple CBC can typically be returned in 1 min. … See more Every hematology analyzer returns a CBC and a three- or five-part WBC differential. However, even the simplest analyzer will return multiple parameters. The most basic analyzer from … See more
