T - B - NK cell lymphocyte subset analysis near me in Hooghly

The T - B - NK cell lymphocyte subset analysis measures the levels and proportions of three key types of lymphocytes (types of white blood cells). It measures T cells, B cells, and Natural Killer (NK) cells in the blood sample. Using flow cytometry, the test identifies these cells based on specific surface markers: CD3, CD4, and CD8 for T cells; CD19 for B cells; and CD16 and CD56 for NK cells.

Each of these lymphocyte subsets plays a unique role in the immune response. T cells (CD3+) are responsible for coordinating and regulating immune activity; CD4+ T helper cells support other immune cells, while CD8+ cytotoxic T cells destroy infected or abnormal cells. B cells (CD19+) produce antibodies that recognize and neutralize pathogens, contributing to long-term immunity. NK cells (CD16+/CD56+) provide rapid defense by attacking virus-infected or tumor cells without prior sensitization.

By analyzing the count and ratio of these subsets, the test helps evaluate immune system function and balance. Abnormalities in any of these cell populations can indicate conditions such as immunodeficiency disorders, autoimmune diseases, viral infections (like HIV), blood cancers, or bone marrow suppression. The results assist doctors in monitoring immune recovery, assessing treatment response, and identifying underlying immune dysfunction.
