CD25 cell marker IVD, antibody

CD25 cell marker in vitro diagnostic (IVD) antibody devices are laboratory tools designed to detect the presence or measure the quantity of CD25, a protein marker found on certain immune cells. Clinically, these tests help diagnose or monitor conditions like autoimmune disorders, graft-versus-host disease, or immune system activation by identifying CD25 expression in blood or tissue samples.

These devices are typically regulated as IVDs, with classification and supply depending on their intended use—whether qualitative (presence/absence) or quantitative (levels). They are usually supplied as reagents or kits for use in flow cytometry, immunohistochemistry, or ELISA assays, requiring proper handling and validation in clinical settings.
