What is a CD3 (Natural Killer Cells) Test in Delhi ?
What is CD3 (NATURAL KILLER CELLS)?
This test measures CD3, a protein found on most T lymphocytes, and also assesses natural killer (NK) cells as part of an immune cell check. CD3 marks T cells that coordinate immune responses. Deficiencies develop over months before symptoms appear. Because symptoms like fatigue and hair loss are non-specific, targeted blood testing is the only reliable way to confirm the diagnosis.
What does CD3 (NATURAL KILLER CELLS) measure?
NK cells help destroy infected or abnormal cells. Measuring these cells shows how well your immune system is working. Doctors use results to detect immune deficiency, monitor HIV or chemotherapy effects, evaluate autoimmune disease, or look for blood cancers. Low or high counts can come from infections, medications, bone marrow problems, or inherited immune disorders.
What symptoms suggest CD3 (NATURAL KILLER CELLS) may be needed?
A doctor may recommend CD3 (NATURAL KILLER CELLS) when a patient reports persistent fatigue, hair thinning, brittle nails, bone or joint pain, frequent infections, poor wound healing, numbness or tingling in the hands or feet, and low mood or poor concentration. If you have these symptoms, GetVisit offers booking and home collection across Mayur Vihar, Rohini, and other parts of Delhi.
How is CD3 (NATURAL KILLER CELLS) performed?
At a GetVisit-partnered lab in Mayur Vihar or Rohini, Delhi, 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 CD3 (NATURAL KILLER CELLS)?
Every GetVisit sample from Mayur Vihar, 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 CD3 (NATURAL KILLER CELLS)?
Risks are minimal. Some people notice a small bruise or brief soreness at the needle site, which settles within a day or two. Serious problems such as infection are very rare when sterile, single-use equipment is used, as it is at every GetVisit collection in Mayur Vihar and Rohini, Delhi.
Did you know?
Natural killer (NK) cells are typically CD3‑negative; CD3 is a T‑cell receptor complex not expressed on conventional NK cells.
CD3 (Natural Killer Cells) Test Preparation in Delhi
Fasting and diet:
You do not need to fast. Have your normal meals, but skip a heavy, oily meal and alcohol the evening before as a general precaution.
What to bring:
Carry your test requisition, a government-issued ID, and any previous reports so results can be compared over time.
Medication:
Hold the specific vitamin or mineral being tested for at least 48 hours beforehand, so the result reflects your stored levels rather than a recent dose.
Timing and slots:
An early slot works best, especially for fasting tests. Home collection is available across Lajpat Nagar, Janakpuri, and the rest of Delhi.

Why Take a CD3 (Natural Killer Cells) Test in Delhi ?
When does a doctor order CD3 (NATURAL KILLER CELLS)?
CD3 (NATURAL KILLER CELLS) is usually part of a lymphocyte subset panel that checks T cells and NK cells. Doctors order it for recurring infections, unexplained fatigue, abnormal blood counts, or to monitor HIV, chemotherapy, or immune-suppressing drugs.
Who should get CD3 (NATURAL KILLER CELLS) done in Delhi?
Vitamin D deficiency is severe in Delhi due to a counterintuitive combination of factors: winter smog (PM2.5 particulate matter physically blocks UV radiation for 4 to 5 months), the widespread practice of wearing full-sleeve winter clothing, and indoor office culture across Connaught Place, Saket, Vasant Kunj, and the growing Dwarka-Rohini suburban corridor. Ironically, Delhi has abundant sunshine but its smog effectively converts it to a vitamin D-deprived city from October to February. Those who benefit most from regular CD3 (NATURAL KILLER CELLS) testing include people on restrictive diets, those recovering from illness, and anyone with persistent tiredness. Confirming a deficiency in Delhi allows correctly dosed supplementation rather than guesswork.
What conditions can CD3 (NATURAL KILLER CELLS) help diagnose?
It helps diagnose immune deficiencies, blood cancers, and autoimmune disease. Abnormal results may come from infections, medications, bone marrow disorders, or inherited immune problems, especially with family history.
What do CD3 (NATURAL KILLER CELLS) results mean?
Serum ferritin below 12 ng/mL: iron deficiency. Ferritin 12–30 ng/mL: iron depletion without yet affecting haemoglobin. Folate below 3 ng/mL: folate deficiency. Zinc below 70 µg/dL: zinc deficiency, associated with impaired immunity and wound healing.
How often should CD3 (NATURAL KILLER CELLS) be repeated?
After starting supplementation, recheck at 8 to 12 weeks to confirm levels are correcting, then every 6 to 12 months once replete. People with ongoing risk factors, restrictive diets, malabsorption, or limited sun exposure, benefit from annual screening even without symptoms.
What happens after CD3 (NATURAL KILLER CELLS) results are ready?
Book a follow-up consultation after reviewing your results. GetVisit stores your reports alongside your previous test history, so your doctor sees your full health trend, not just today's snapshot. This longitudinal context significantly improves the clinical value of each repeat test.
