What is a CD3 (Natural Killer Cells) Test in Patna ?
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. Sample collection for Patna is available at labs and at home across Exhibition Road, Kankarbagh, and surrounding neighbourhoods.
How is CD3 (NATURAL KILLER CELLS) performed?
Collection is a routine blood draw. Using a single-use sterile needle, the phlebotomist takes a small sample from a vein in your arm; GetVisit's team in Exhibition Road and Kankarbagh, Patna then barcodes and transports it under controlled conditions to the NABL lab.
How accurate is CD3 (NATURAL KILLER CELLS)?
Results are analytically reliable because GetVisit's Patna logistics network maintains proper cold-chain transport from your Exhibition Road or Kankarbagh collection point to the processing lab, preserving sample integrity. NABL independently audits quality control at regular intervals.
Are there any risks to CD3 (NATURAL KILLER CELLS)?
There are no significant risks beyond those of a standard blood draw. For your appointment in Exhibition Road or Kankarbagh, Patna, 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?
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 Patna
Managing medication:
Avoid supplements of the nutrient being measured for a day or two before the test; taking one shortly before can inflate the reading.
Fasting instructions:
No special diet or fasting is needed. Carry on normally; just stay hydrated and avoid alcohol the night before.
Timing:
Choose a morning slot for the most consistent results. Same-day home collection is offered throughout Patna, Patna City and Kankarbagh included.
What to bring along:
Bring your doctor's prescription, a valid photo ID, and your insurance card if you're using cashless OPD. Loose sleeves make collection easier.

Why Take a CD3 (Natural Killer Cells) Test in Patna ?
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 Patna?
Iron-deficiency anaemia is common in Bihar, particularly among women and adolescents, and vitamin D deficiency is widespread despite strong sunshine due to indoor routines. B12 deficiency is frequent in the largely vegetarian population across Boring Road and Patliputra Colony. Deficiency testing benefits vegetarians and vegans, pregnant and breastfeeding women, older adults, people with limited sun exposure, and anyone with unexplained fatigue or hair loss. In Patna, indoor office culture across Exhibition Road, Kankarbagh, and similar areas makes vitamin D deficiency especially common despite ample sunshine.
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?
Vitamin D below 20 ng/mL: deficiency, loading dose (typically 60, 000 IU weekly for 8-12 weeks) followed by maintenance. Vitamin D 20-30 ng/mL: insufficiency, moderate supplementation. Above 100 ng/mL: toxicity risk. Vitamin B12 below 200 pg/mL: deficiency, oral or injectable supplementation depending on cause.
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 your CD3 (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.
