CK19 Metastasis Detection Test - Immunohistochemistry (IHC) for Cytokeratin 19 (CK19)

Immunohistochemistry for CK19 (Cytokeratin 19) aims to detect this specific type of low molecular weight keratin (intermediate filament). CK19 is a highly sensitive marker expressed in most carcinomas, especially Adenocarcinoma, and is widely used in techniques like Sentinel Lymph Node Biopsy (SLNB) in breast cancer and in assessing tumor spread to bone marrow.
