What is a CD16 (Natural Killer Cells) Test in Delhi ?

What is CD16 (Natural Killer Cells)?

This test measures CD16, a protein found on a type of white blood cell called natural killer (NK) cells. NK cells are part of your innate immune system. Accurate organism identification is clinically essential , typhoid, dengue, and malaria each require different treatment, and the wrong empirical approach delays recovery.

What does CD16 (Natural Killer Cells) measure?

They help destroy virus-infected cells and some cancer cells. Measuring CD16 helps show how many NK cells are present and how they function. Doctors use the result to check for immune system problems. It can help diagnose recurrent infections, immune deficiencies, certain blood cancers, and to monitor response to treatments such as cancer therapy or immunosuppressive drugs.

What symptoms suggest CD16 (Natural Killer Cells) may be needed?

A doctor may recommend CD16 (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. Sample collection for Delhi is available at labs and at home across Shahdara, Dilshad Garden, and surrounding neighbourhoods.

How is CD16 (Natural Killer Cells) performed?

GetVisit home collection in Shahdara or Dilshad Garden, Delhi: a certified phlebotomist arrives at your address at your chosen slot (available from 6:00 AM), brings all sterile single-use equipment, draws the sample, and dispatches it to the NABL-accredited lab. Your digital report is delivered to your GetVisit profile the same day for most standard blood tests.

How accurate is CD16 (Natural Killer Cells)?

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

Are there any risks to CD16 (Natural Killer Cells)?

Beyond a brief pinch, CD16 (Natural Killer Cells) carries almost no risk. Keep the arm relaxed during the draw, press gently on the site afterwards, and avoid heavy lifting with that arm for about an hour.

Did you know?

CD16 (FcγRIII) on NK cells binds the Fc portion of IgG on antibody-coated targets, triggering antibody-dependent cellular cytotoxicity (ADCC).

CD16 (Natural Killer Cells) Test Preparation in Delhi

Your medicines:

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

Before you come:

No fasting is required. Eat and drink as usual, stay well hydrated, and simply avoid alcohol and heavy exercise in the 12 hours before your appointment.

Booking your slot:

Book whenever is convenient; for fasting or hormone tests an early-morning slot is ideal. GetVisit covers Vasant Kunj, Saket, and all of Delhi.

Documents and clothing:

Keep your prescription and ID handy, along with your OPD insurance details if applicable. Wear sleeves that roll up easily.

CD16 (Natural Killer Cells) Test Parameters in Delhi

Single standalone test:

CD16 (Natural Killer Cells). Can be ordered individually or as part of a preventive health package on GetVisit.

Why Take a CD16 (Natural Killer Cells) Test in Delhi ?

When does a doctor order CD16 (Natural Killer Cells)?

CD16 (Natural Killer Cells) is often part of an immune panel or lymphocyte subset profile performed by flow cytometry. Doctors may order it for recurrent or unusual infections, unexplained low blood counts, suspected immune deficiency, or to monitor cancer treatment and transplant patients.

Who should get CD16 (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. CD16 (Natural Killer Cells) testing is important for symptomatic patients, for confirming recovery, and for household members of a confirmed case. Testing early in Delhi's fever season prevents the complications that come from treating the wrong infection.

What conditions can CD16 (Natural Killer Cells) help diagnose?

Abnormal results can come from infections, autoimmune diseases, chemotherapy, steroids, or inherited immune defects. A family history of primary immunodeficiency or recurrent infections may make this test especially important.

What do CD16 (Natural Killer Cells) results mean?

Your result is read against the reference range printed on your GetVisit report for your age and sex, and always alongside your symptoms and history. A single value slightly outside the range does not by itself confirm a problem, your doctor decides whether it is significant. The specific high and low patterns for this test are explained in the FAQs below.

How often should CD16 (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 CD16 (Natural Killer Cells) results are ready?

After the lab authorises your results, the report is uploaded to your GetVisit account and saved for future comparison. If anything falls outside the expected range, your doctor can advise whether it needs a repeat test, a lifestyle change, or a specialist opinion.

What does CD16 do on NK cells?plus

CD16 (FcγRIII) on NK cells binds the Fc portion of IgG on antibody-coated targets, triggering antibody-dependent cellular cytotoxicity (ADCC). Engagement induces ITAM-mediated signaling, NK cell activation, degranulation with perforin/granzymes release, and cytokine production (e.g. IFN‑γ), enabling killing of infected or tumor cells. CD16 is a low‑affinity Fc receptor; genetic variants influence its binding and ADCC potency.

What is the difference between CD16 and CD56 NK cells?plus

NK cells segregate into CD56bright CD16−/dim and CD56dim CD16+ subsets. CD56bright CD16−/dim are mainly in lymphoid tissues, produce high levels of cytokines (e.g. IFN-γ), have lower direct cytotoxicity, and respond strongly to cytokines like IL-2. CD56dim CD16+ dominate blood, express perforin/granzyme, are highly cytotoxic and mediate antibody-dependent cellular cytotoxicity via CD16 (FcγRIIIa).

What is CD16 a marker for?plus

CD16 (FcγRIII) is an Fc gamma receptor expressed mainly on natural killer (NK) cells and on certain myeloid cells , neutrophils, monocytes and macrophages. It’s used as a marker to identify NK cells and mature neutrophils and reflects capacity for antibody-dependent cellular cytotoxicity (ADCC) and immune complex handling. Two isoforms exist: CD16a (NK cells, monocytes/macrophages) and CD16b (neutrophils).

Do NKT cells express CD16?plus

Most canonical NKT cells (CD3+ CD1d-restricted invariant NKT) do not express CD16 (FcγRIII). They can share some NK receptors (e.g. CD56, NKG2D), but CD16 is typically absent or only present on rare/activated NKT-like subsets. Thus CD16 is not a defining marker for classical NKT cells; any CD16 positivity is variable and subset-dependent.

Can I take my diabetes medication before CD16 (Natural Killer Cells)?plus

If you take insulin or diabetes tablets and are fasting for CD16 (Natural Killer Cells), ask your doctor whether to delay the dose until after the sample is collected, to avoid a low-sugar episode.

Can I drink coffee or tea before CD16 (Natural Killer Cells)?plus

If CD16 (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.
