CD23 cell marker IVD, antibody

CD23 cell marker in vitro diagnostic (IVD) devices are laboratory tests designed to detect the presence or concentration of the CD23 protein in biological samples, such as blood or tissue. These tests use antibodies to identify CD23, a marker often linked to immune cell activity and conditions like chronic lymphocytic leukemia (CLL) or allergic disorders, aiding in diagnosis or monitoring of related diseases.

These devices are typically regulated as IVDs, with classification and supply depending on their intended use—whether for qualitative (presence/absence) or quantitative (levels) detection. They are usually supplied as kits containing reagents, controls, and instructions for use, requiring proper laboratory handling and validation to ensure accurate results.
