flow cytometry

This term refers to a specialized analytical technique used primarily in immunology, hematology, and cell biology. It is characterized by the high-throughput analysis of single cells, allowing researchers to identify specific cell types based on the presence of fluorescently labeled antibodies.

In a clinical or laboratory setting, the term is used as a technical noun. It is an uncountable mass noun because it describes a methodology or a process rather than a discrete object. You would refer to "the use of flow cytometry" or "performing flow cytometry" rather than "a flow cytometry."
