Cytometry is a technique used to measure various characteristics of individual cells, such as their size, shape and internal complexity. Cytometric analysis involves counting or measuring specific cellular components, such as DNA content, protein concentration, or other biomarkers that can provide information about the health, developmental stage, or functional state of a particular cell population. The term "cytometric" refers to any method used in cytometry, including flow cytometry and image cytometry, which are techniques for analyzing cells by measuring their light scatter, fluorescence emission, or other physical properties that can be detected using specialized instruments.
