What is a CD3 (Natural Killer Cells) Test in Madurai ?
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?
CD3 (NATURAL KILLER CELLS) is generally requested as part of a nutritional status assessment. Doctors commonly investigate this area when someone 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.
