CD5, IHC with Interpretation
Use
This immunohistochemical (IHC) test evaluates CD5 expression, which is typically found on most thymocytes, immature peripheral T cells, mature T cells, and mantle zone B cells, aiding in distinguishing T‑cell lineage and identifying certain B‑cell neoplasms such as mantle cell lymphoma, chronic lymphocytic leukemia, and other lymphoid malignancies.
