What is a CD79a (B Lymphoid Cell Marker) Test?

The CD79a (B Lymphoid Cell Marker) test detects the CD79a protein on cells in a tissue sample. CD79a is part of the B‑cell receptor and shows whether cells come from the B‑lymphocyte family. This matters because it helps doctors tell B‑cell cancers from other cell types. It is commonly used on biopsies or bone marrow samples. Results help diagnose and classify lymphomas and leukemias. Doctors use CD79a along with other markers to plan treatment and monitor response. It can also help when common B‑cell markers are missing, giving a clearer picture of cell type and disease behavior.

CD79a (B Lymphoid Cell Marker) Test Preparation

No special preparation is required.

CD79a (B Lymphoid Cell Marker) Test Parameters

The CD79a (B Lymphoid 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 CD79a (B Lymphoid Cell Marker) Test?

CD79a (B Lymphoid Cell Marker) is usually run as part of an immunohistochemistry panel for suspected lymphomas or leukemias. Doctors may order it when patients have swollen lymph nodes, unexplained lumps, night sweats, weight loss, or abnormal blood counts. It helps identify B‑cell cancers and some related disorders. Abnormal results are most often caused by hematologic disease, reactive B‑cell growth, or sample issues; family history of blood cancers may increase the need for testing.

Frequently asked questions

What is CD79a a marker for?plus

CD79a is a B‑cell lineage marker expressed in precursor and mature B cells (and often in plasma cells). It is a component of the B‑cell receptor complex and is widely used in immunohistochemistry and flow cytometry to identify B‑cell neoplasms—such as B‑ALL, CLL, and various B‑cell lymphomas—even when surface immunoglobulin is absent.

What is CD79b a marker for?plus

CD79b is a B‑cell lineage marker: it encodes part of the B‑cell receptor complex (Igβ) expressed on mature B cells and many B‑cell malignancies. It’s used in immunohistochemistry and flow cytometry to identify and classify B‑cell neoplasms—for example diffuse large B‑cell lymphoma, follicular lymphoma and chronic lymphocytic leukemia—and to inform diagnosis and treatment choices.

What are the CD markers for B-cell lymphoma?plus

Most B‑cell lymphomas express pan‑B markers: CD19, CD20, CD22 and CD79a (and PAX5). Subtype markers include CD10 (follicular/Burkitt), CD5 (CLL/SLL, mantle cell), CD23 (CLL positive, mantle cell usually negative), CD43, CD30 (some DLBCL), and CD11c/CD25/CD103 in hairy cell leukemia. Light‑chain restriction (kappa or lambda) is also used diagnostically. Immunophenotyping by flow cytometry or immunohistochemistry defines diagnosis and guides subclassification.

What does CD79 positive mean?plus

CD79 positive means a cell expresses CD79 proteins (CD79a/CD79b), components of the B‑cell receptor complex. This marker indicates B‑cell lineage and is detected by immunophenotyping to help diagnose and classify B‑cell leukemias and lymphomas. CD79 positivity aids pathologists in confirming B‑cell origin and can inform prognosis and selection of targeted therapies.

What CD markers indicate leukemia?plus

Leukemia is identified by aberrant CD marker patterns on blasts via flow cytometry. Common markers: myeloid — CD13, CD33, CD117, CD34 and myeloperoxidase (MPO); B‑lineage — CD19, CD10, CD20, CD22, CD79a; T‑lineage — CD3, CD2, CD7, CD5. Additional markers (CD45, TdT, CD56) and abnormal co‑expression help subtype disease and guide diagnosis and treatment.

Are hematogones CD79a positive?plus

Yes. Hematogones, the normal B‑cell precursors in bone marrow, typically express CD79a. CD79a positivity is seen across maturation stages along with CD19, CD10 and bright CD38 (and TdT or CD34 in earlier precursors). This immunophenotype helps distinguish benign hematogones from malignant B‑lymphoblasts on flow cytometry when interpreted in the clinical context.
