What is a CD56 (Natural Killer Cells) Test in Delhi ?
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. In Delhi, you can book this test online with home collection available in Karol Bagh, Rohini, and beyond.
How is CD56 (Natural Killer Cells) performed?
You can have the sample for CD56 (Natural Killer Cells) taken at home in Karol Bagh or Rohini, Delhi, or at a partner lab. The phlebotomist draws a small amount of blood, applies a cotton swab with light pressure, and dispatches the sample to the NABL-accredited lab the same day.
How accurate is CD56 (Natural Killer Cells)?
Every GetVisit sample from Karol Bagh, Rohini, and across Delhi is processed at NABL-accredited labs that use internationally calibrated reference standards, pass external quality assessments, and maintain internal quality control at every shift. Reports are accepted by all major hospital networks, specialists, and insurance providers in India.
Are there any risks to CD56 (Natural Killer Cells)?
A blood draw for CD56 (Natural Killer Cells) is very safe. Occasionally there is minor bruising or light-headedness; sitting for a couple of minutes afterwards at the Karol Bagh or Rohini, Delhi collection point usually prevents this.
Did you know?
CD56 marks human natural killer (NK) cells, which provide innate immune surveillance.

Why Take a CD56 (Natural Killer Cells) Test in Delhi ?
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 Delhi?
Delhi's 30+ million population, India's most severe urban air pollution, one of the country's highest combined diabetes and cardiovascular disease burdens, extreme seasonal temperature range (from 3°C in January to 48°C in May), and monsoon infection risk across Dwarka, Rohini, Shahdara, and Uttam Nagar make regular preventive diagnostic testing an essential part of health management for all city residents. Anyone with fever or flu-like illness in Delhi, 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 Lajpat Nagar, Dilshad Garden, and flood-prone localities face higher seasonal exposure to mosquito- and water-borne infections.
What conditions can CD56 (Natural Killer Cells) help diagnose?
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 Delhi's monsoon fever season, prompt retesting is advised for any new febrile illness.
What happens after CD56 (Natural Killer Cells) results are ready?
Reports arrive digitally and remain in your GetVisit history, so repeat tests can be tracked over months and years. Review anything unexpected with your doctor before changing medication or lifestyle, and use the app to book a follow-up if needed.
