T lymphocyte IVD, kit, fluorescent activated cell sorting/flow cytometry (FACS/Flow)

This category includes kits and reagent sets designed to identify and measure T lymphocytes in patient samples using fluorescent activated cell sorting or flow cytometry technology. These devices are used clinically to assess immune function, monitor disease progression, or support diagnosis in conditions such as immunodeficiency, autoimmune disorders, or post-transplant care.

Devices in this category are in vitro diagnostic (IVD) products that rely on specific antibody or ligand binding to detect T cell subsets via fluorescence-based analysis. They are supplied as complete kits containing all necessary reagents and controls for use with standard flow cytometry instrumentation, and their regulation depends on the intended use and jurisdiction, typically falling under IVD regulatory frameworks without implying a specific device class.
