CD138 (Plasma Cell Marker)
Measures CD138 protein on tissue to identify and count plasma cells, helping diagnose plasma cell disorders.
What is a CD138 (Plasma Cell Marker) Test?
CD138 testing detects a protein called CD138 on the surface of plasma cells. Plasma cells make antibodies and are mainly found in bone marrow and some tissues. The test helps pathologists find and count plasma cells in biopsy samples. This matters because large numbers of plasma cells can indicate conditions such as multiple myeloma, plasmacytoma, or plasma cell–rich inflammation. Doctors use CD138 staining on bone marrow or tumor biopsies to confirm diagnosis, guide treatment choices, and check for leftover disease after therapy. Results are interpreted together with blood work, imaging, and clinical findings to direct care.
CD138 (Plasma Cell Marker) Test Preparation
No special preparation is required.
CD138 (Plasma Cell Marker) Test Parameters

Why Take a CD138 (Plasma Cell Marker) Test?
CD138 (Plasma Cell Marker) is used in pathology panels for suspected multiple myeloma, plasmacytoma, or plasma cell–rich tumors. Doctors may order it when a patient has unexplained bone pain, anemia, recurrent infections, or abnormal blood or urine tests. The test helps confirm a plasma cell diagnosis, measure how many plasma cells are present, and monitor response to treatment. Elevated levels usually reflect cancer or marked inflammation, and family history of blood cancers may make testing more urgent.
