In histology, various techniques are used to measure cell volume, including: - Flow Cytometry: This technique uses lasers to measure the physical and chemical characteristics of cells in a fluid as they pass through a laser beam. - Hematology Analyzers: These automated machines use electrical impedance or light scatter methods to measure cell volume and other parameters. - Microscopy: Advanced imaging techniques, such as confocal microscopy, allow precise measurement of cell and organelle volume.
