What is a CD23 (CLL Segregation Marker) Test in Bangalore ?

The CD23 (CLL Segregation Marker) test measures the CD23 protein on the surface of B lymphocytes. CD23 is a cell surface receptor involved in immune cell signaling. Measuring CD23 helps doctors identify the type of B-cell involved in blood disorders. High CD23 expression is often seen in chronic lymphocytic leukemia (CLL). The test helps distinguish CLL from other B-cell cancers. Doctors use it with other markers in a flow cytometry panel on blood or bone marrow samples. Results support diagnosis, guide treatment choices, and help monitor disease activity or response to therapy. Clinicians interpret CD23 alongside blood counts, symptoms, and other lab tests.

No special preparation is required.

CD23 (CLL Segregation Marker) Test Parameters in Bangalore

The CD23 (CLL Segregation 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 CD23 (CLL Segregation Marker) Test in Bangalore ?

CD23 (CLL Segregation Marker) is usually run as part of a leukemia immunophenotyping panel using flow cytometry. Doctors order it when blood counts are abnormal, lymphocytes are high, or there are swollen lymph nodes, fatigue, or repeated infections. It helps diagnose and monitor chronic lymphocytic leukemia and distinguish it from other B-cell cancers. Abnormal results come from blood cancers or unusual B‑cell activation; family history of blood malignancies may prompt testing.

What is CD23 a marker for in Bangalore?plus

CD23 is the low‑affinity IgE receptor (FcεRII) expressed mainly on mature and activated B lymphocytes, some monocytes/macrophages and follicular dendritic cells. It indicates B‑cell activation and participates in IgE regulation, antigen presentation and immune regulation. In diagnostic labs, CD23 immunostaining helps distinguish chronic lymphocytic leukemia (CD23‑positive) from mantle cell lymphoma (typically CD23‑negative).

What is CD23 expression in CLL in Bangalore?plus

CD23 is the low‑affinity IgE receptor commonly expressed on CLL B cells. Strong surface CD23 positivity, along with CD5 and typical B‑cell markers (CD19/CD20), helps distinguish CLL from other B‑cell neoplasms, notably mantle cell lymphoma which is usually CD23‑negative. Soluble CD23 levels can reflect tumor burden and correlate with disease activity and prognosis.

What are the CD markers for CLL leukemia in Bangalore?plus

Chronic lymphocytic leukemia immunophenotype: CD19+, CD5+, CD23+, CD20 dim/weak, surface immunoglobulin (sIg) weak, CD43+, CD200+, and CD79b weak; typically CD10– and FMC7–. CD38 expression is variable and used prognostically. These markers are identified by flow cytometry and help distinguish CLL from other B‑cell lymphoproliferative disorders. ZAP-70 is an intracellular prognostic marker often assessed separately.

Is CLL CD20 positive in Bangalore?plus

Yes. Chronic lymphocytic leukemia (CLL) B cells typically express CD20, but expression is often weaker and more variable than on normal B cells. CLL cells are characteristically CD19+, CD5+, CD23+ with low surface immunoglobulin and reduced CD20 density, which can affect responses to anti‑CD20 monoclonal antibodies such as rituximab; newer agents may overcome low CD20 levels.

Is follicular lymphoma CD23 positive in Bangalore?plus

Follicular lymphoma is usually CD20+, CD10+ and BCL2/BCL6 positive; CD23 is typically negative. However, CD23 expression can be variable and may be detected in a minority of cases, often weak or focal. Therefore CD23 status alone is not diagnostic; interpretation should rely on the full immunophenotypic profile, morphology, and genetic findings.

What cells express CD23 in Bangalore?plus

CD23 (FcεRII) is primarily expressed on mature and activated B lymphocytes and on follicular dendritic cells. It is also found on activated monocytes and macrophages, certain dendritic-cell subsets, eosinophils, and some epithelial cells. CD23 expression can be upregulated by cytokines and immune activation, reflecting roles in IgE binding, antigen presentation, B‑cell regulation and modulation of allergic and inflammatory responses.
