ALK Protein Test for Lymphoma - Immunohistochemistry (IHC) for ALK Lymphoma

A qualitative immunohistochemical (IHC) assay using a monoclonal antibody against anaplastic lymphoma kinase (ALK) protein on tissue sections from a lymph node or infected tissue. It reveals aberrant expression of ALK protein resulting from a genetic rearrangement, a hallmark of anaplastic large cell lymphoma (ALK+ALCL) and some other tumors.
