What is a CD19 (Pan B Cell Marker) Test in Bangalore ?

The CD19 (Pan B Cell Marker) test measures the CD19 protein on the surface of B lymphocytes. B cells are white blood cells that make antibodies and help fight infection. Measuring CD19 shows how many B cells are present and whether their pattern looks normal. This helps detect B‑cell leukemias and lymphomas, identify some immune deficiencies, and monitor therapies that affect B cells. Doctors commonly use it as part of flow cytometry immunophenotyping on blood or tissue samples. It helps confirm a diagnosis, guide treatment choices, and track response or relapse over time. Results are interpreted with other blood tests and clinical information. It can also be used before and after therapies like CAR‑T cell treatment to measure changes in B cells. Your doctor will explain what abnormal findings mean for your care.

CD19 (Pan B Cell Marker) Test Parameters in Bangalore

The CD19 (Pan B Cell Marker) test evaluates various parameters related to the different components. Here are the main parameters that are checked in the test:

  • Single test

Why Take a CD19 (Pan B Cell Marker) Test in Bangalore ?

CD19 (Pan B Cell Marker) is included in flow cytometry immunophenotyping panels used to evaluate blood and bone marrow. Doctors may order it for unexplained infections, abnormal white cell counts, swollen lymph nodes, or suspected leukemia/lymphoma. It helps diagnose and monitor B‑cell cancers and immune defects. Abnormal results arise from B‑cell malignancy, immunodeficiency, certain infections, or B‑cell–depleting therapies; family history of blood cancers may prompt testing.

What is CD19 a marker for in Bangalore?plus

CD19 is a transmembrane protein and a pan–B-cell marker expressed throughout B-cell development from pro-B cells to mature B cells, but typically lost when B cells differentiate into plasma cells. It is widely used to identify and classify normal and malignant B-cell populations in blood, bone marrow and lymphoid tissues, and serves as a target for B-cell–directed therapies.

What does it mean when CD19 is positive in Bangalore?plus

CD19-positive means cells express the CD19 protein on their surface, identifying them as B lymphocytes. In clinical testing (flow cytometry or immunohistochemistry) CD19 positivity indicates B‑cell lineage, helping diagnose and classify B‑cell leukemias and lymphomas, monitor disease burden or minimal residual disease, and select or evaluate therapies that target CD19 (for example, monoclonal antibodies or CAR‑T cells).

What is a pan B cell marker in Bangalore?plus

A pan B‑cell marker is a surface or lineage protein expressed broadly across B lymphocyte stages, used to identify B cells in diagnostics and guide therapies. Common pan‑B markers include CD19 and CD20 (widely used for flow cytometry and targeted treatments); CD79a and PAX5 are additional lineage markers useful in pathology, with varying expression on plasma cells.

What is the role of CD19 in B cells in Bangalore?plus

CD19 is a transmembrane co-receptor expressed through B‑cell development that amplifies B‑cell receptor (BCR) signaling by recruiting kinases and lowering the activation threshold. It forms a complex with CD21 and CD81, supporting B‑cell activation, proliferation, differentiation, antibody responses, and survival. CD19 is also used as a lineage marker and a therapeutic target in B‑cell malignancies and immunotherapies.

What cancers are CD19 positive in Bangalore?plus

CD19 is expressed on most B‑cell lineage malignancies: B‑cell acute lymphoblastic leukemia (B‑ALL), chronic lymphocytic leukemia (CLL), and many non‑Hodgkin lymphomas (diffuse large B‑cell, follicular, mantle‑cell, Burkitt, marginal‑zone). It’s also found in hairy cell leukemia and precursor B‑cell lymphoblastic lymphoma. CD19 is generally absent or low on mature plasma‑cell myeloma and is a common immunotherapy target.

What disease is associated with CD19 in Bangalore?plus

CD19 is a B‑cell surface protein primarily associated with B‑cell malignancies. It’s a hallmark of diseases such as B‑cell acute lymphoblastic leukemia (B‑ALL), chronic lymphocytic leukemia (CLL), and many non‑Hodgkin B‑cell lymphomas (including diffuse large B‑cell lymphoma). CD19 is widely used as a diagnostic marker and therapeutic target (for example, in CAR‑T cell therapies) in these B‑cell disorders.
