from the same data as the platelet count. True or False True In healthy patients, there is an inverse relationship between platelet count and size. What are the three steps in a laser Cytochemical reactions prepare the blood cells technology? for analysis. A cytometer measures specific cell properties. Algorithms convert these measurements into familiar results for cell classification, cell count, cell size, and hemoglobinization. RBC/platelet channel uses a laser-based The basophil/lobularity channel. optical assembly that is shared with what channel? Where is the platelet histogram derived? The platelet histogram is derived from measurements made with the high-angle detector. What is the mode of the measured platelet MPV volumes? Most flow-cell instruments can at the rate of 5,000 to 10,000 cells/sec. simultaneously analyze multiple parameters at what rate? In flow cytometry, the cellular analysis The cellular analysis yields quantitative data yields what properties of individual cells? about the chemical and physical properties of individual cells. Major advances in this technology are owing The ability to produce monoclonal to several factors, what are these factors? antibodies resulted in the subsequent development of specific surface markers for various subpopulations of cells. The development of new fluorescent probes for DNA, RNA, and other cellular components increased the variety of possible applications at the molecular and cellular levels. The expansion of computer applications has improved the instrumentation technology, making it easier to operate and more practical for use in clinical as well as research laboratories. In hematology, automated differentials can Determination of cell volume by electrical be based on a variety of principles which impedance or forward light scatter, includes what? cytochemistry or peroxidase staining, and VCS technology. Because single-cell suspensions of hematology and immunology peripheral blood and bone marrow are easy to obtain, most clinical applications of flow cytometry are in the specialties of __________ and ______________. Reticulocytes Enumeration by flow accurate, precise, and cost-effective.
