What is a CD56 (Natural Killer Cells) Test in Bangalore ?

The CD56 (Natural Killer Cells) test measures the number and proportion of white blood cells that carry the CD56 marker. These CD56-positive cells are natural killer (NK) cells. NK cells are part of the innate immune system. They help control viral infections and can destroy abnormal or cancerous cells. Measuring CD56 helps detect immune deficiencies, monitor some blood cancers, and follow immune treatments. Doctors use it with other blood and immune tests to investigate recurrent infections, unexplained fevers, or abnormal blood counts. Labs usually report NK cell count or percentage. Abnormal results can reflect infection, autoimmune activity, bone marrow or lymphoid disease, medications, or inherited immune problems.

No special preparation is required.

CD56 (Natural Killer Cells) Test Parameters in Bangalore

The CD56 (Natural Killer Cells) 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 CD56 (Natural Killer Cells) Test in Bangalore ?

CD56 (Natural Killer Cells) is often ordered as part of an immune panel or flow cytometry profile. Doctors may request it when a patient has recurrent or severe infections, unexplained fevers, abnormal blood counts, or suspected immune or blood cancers. Abnormal results can be caused by viral infections, autoimmune disease, bone marrow disorders, cancer, or medications like steroids and chemotherapy. A family history of immune disorders may prompt testing.

What do CD56 NK cells do in Bangalore?plus

CD56 marks human natural killer (NK) cells, which provide innate immune surveillance. CD56bright NK cells, mainly in lymphoid tissues, secrete cytokines (IFN-γ, TNF) to regulate immune responses. CD56dim NK cells, predominant in blood, are highly cytotoxic—killing virus-infected and tumor cells via perforin/granzymes and antibody-dependent cellular cytotoxicity. NKs also shape adaptive immunity and respond rapidly without prior sensitization.

What tumors are positive for CD56 in Bangalore?plus

Tumors positive for CD56 (NCAM) include neuroendocrine neoplasms — small cell lung carcinoma, carcinoid tumors, medullary thyroid carcinoma, neuroblastoma, and Merkel cell carcinoma; hematologic malignancies — NK‑cell and NK/T‑cell lymphomas and many multiple myelomas; and some acute myeloid leukemias. CD56 is a neural/neuroendocrine and NK‑cell marker, so expression is seen in tumors of those lineages.

What does a positive CD56 mean in Bangalore?plus

CD56 positivity means cells express the CD56 (NCAM) surface marker, commonly identifying natural killer (NK) cells and some T‑cell subsets. In clinical testing, CD56+ can indicate an NK‑cell population or abnormal expression seen in certain hematologic malignancies (some leukemias/lymphomas) and neuroendocrine tumors. Interpretation depends on cell type and other markers; clinical correlation and further testing are needed.

What is CD56 also known as in Bangalore?plus

CD56 is the cluster-of-differentiation name for the neural cell adhesion molecule (NCAM, also called NCAM1), a cell-surface glycoprotein involved in adhesion, migration and signaling. It’s expressed on natural killer (NK) cells, subsets of T cells and neuronal tissues. NCAM has multiple isoforms (e.g., 120, 140, 180 kDa) important in neural development and immune recognition.

What diseases are associated with CD56 in Bangalore?plus

CD56 (NCAM) is expressed on NK cells and neural and neuroendocrine tissues. High or aberrant CD56 expression is linked to NK‑cell leukemias and extranodal NK/T‑cell lymphoma, some acute leukemias and AML subsets, and multiple myeloma (with prognostic significance). CD56 is also found on neuroendocrine and neural tumors such as neuroblastoma and small‑cell lung cancer. Altered CD56+ NK cell subsets appear in certain infections and autoimmune diseases.

Are NK cells good or bad in Bangalore?plus

Natural killer (NK) cells are generally beneficial: they’re innate immune cells that rapidly detect and destroy virus-infected and cancerous cells and help shape immune responses. However, when overactive or misdirected they can cause tissue damage and contribute to inflammatory or autoimmune conditions. Overall they’re crucial for early defense but must be properly regulated to avoid harm.
