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

What is CD56 (Natural Killer Cells)?

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. Accurate organism identification is clinically essential, typhoid, dengue, and malaria each require different treatment, and the wrong empirical approach delays recovery.

What does CD56 (Natural Killer Cells) measure?

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.

What symptoms suggest CD56 (Natural Killer Cells) may be needed?

A doctor may recommend CD56 (Natural Killer Cells) when a patient reports sudden fever (above 38.5°C), body aches and chills, persistent headache, nausea or vomiting, abdominal pain, skin rash, joint pain, and extreme fatigue. If you have these symptoms, GetVisit offers booking and home collection across Pakhowal Road, Ghumar Mandi, and other parts of Ludhiana.

How is CD56 (Natural Killer Cells) performed?

At a GetVisit-partnered lab in Pakhowal Road or Ghumar Mandi, Ludhiana, a certified phlebotomist cleans the inner elbow, locates a vein, and draws the required blood (typically 5 to 10 mL). The procedure takes 3 to 5 minutes. You feel a brief pinch at insertion and mild pressure during collection, then can eat, drive, and resume all activities immediately afterwards.

How accurate is CD56 (Natural Killer Cells)?

Results are analytically reliable because GetVisit's Ludhiana logistics network maintains proper cold-chain transport from your Pakhowal Road or Ghumar Mandi collection point to the processing lab, preserving sample integrity. NABL independently audits quality control at regular intervals.

Are there any risks to CD56 (Natural Killer Cells)?

There are no significant risks beyond those of a standard blood draw. For your appointment in Pakhowal Road or Ghumar Mandi, Ludhiana, drink 2 to 3 glasses of water beforehand and stay seated for 2 to 3 minutes afterwards, as vasovagal fainting (rare) is more likely if you are fasting, anxious, or dehydrated. Tell the phlebotomist if you have fainted during previous draws.

Did you know?

CD56 marks human natural killer (NK) cells, which provide innate immune surveillance.

CD56 (Natural Killer Cells) Test Preparation in Ludhiana

Medication guidance:

Unless your physician advises a change, keep taking your usual prescriptions as normal.

Diet and fasting:

Eat and drink as you normally would; fasting is not required. Try to avoid a very fatty meal or alcohol right before the appointment.

When to book:

Why Take a CD56 (Natural Killer Cells) Test in Ludhiana ?

When does a doctor order CD56 (Natural Killer Cells)?

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.

Who should get CD56 (Natural Killer Cells) done in Ludhiana?

Ludhiana's large industrial workforce, ghee- and dairy-rich Punjabi diet driving high diabetes and cardiovascular prevalence, winter air pollution, and seasonal monsoon infections make regular preventive diagnostic testing an important habit for residents citywide. Anyone with fever or flu-like illness in Ludhiana, especially during and after the monsoon, benefits from prompt CD56 (Natural Killer Cells) testing, as do travellers returning from endemic areas and people caring for someone already infected. Residents of Pakhowal Road, Ghumar Mandi, and flood-prone localities face higher seasonal exposure to mosquito- and water-borne infections.

What conditions can CD56 (Natural Killer Cells) help diagnose?

The test helps confirm or exclude the specific infection it targets and can distinguish an active, current infection from past exposure or acquired immunity. This precision allows treatment to be directed at the actual cause rather than relying on broad-spectrum guesswork. 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 (Natural Killer Cells) results mean?

Higher or positive results: 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. Your doctor reads the value against the reference range on your report and your symptoms, and may repeat a borderline result to confirm it.

How often should CD56 (Natural Killer Cells) be repeated?

Infection tests are ordered when symptoms are present rather than on a fixed schedule. Repeat testing may be needed to confirm recovery, to check clearance after treatment, or if fever recurs. During Ludhiana's monsoon fever season, prompt retesting is advised for any new febrile illness.

What happens after your CD56 (Natural Killer Cells) results are ready?

You will be notified the moment results are ready, usually the same day for routine tests. Open the report in the GetVisit app to see each value beside its reference range, share it with your doctor in a tap, or book a specialist consultation to talk it through.

What do CD56 NK cells do?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?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?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?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.

Can I drink coffee or tea before CD56 (Natural Killer Cells)?plus

If CD56 (Natural Killer Cells) needs fasting, avoid tea and coffee (even without sugar) during the fasting window, as they can affect some results; plain water is fine. If no fasting is required, your usual drinks are okay.

Can I take my diabetes medication before CD56 (Natural Killer Cells)?plus

If you take insulin or diabetes tablets and are fasting for CD56 (Natural Killer Cells), ask your doctor whether to delay the dose until after the sample is collected, to avoid a low-sugar episode.
