CD20 B-Cell Marker Test - Immunohistochemistry (IHC) for CD20 (B-Cell)

Immunohistochemistry (IHC) for the CD20 marker is a technique using antibodies to detect the presence of CD20 protein on the cell surface. CD20 is a highly specific marker for most stages of B-cell development, making it a fundamental diagnostic tool in classifying B-cell lymphomas and assessing B-cell density in autoimmune diseases or chronic inflammations.
