Natural Killer Cells (Lymphocyte Subsets) by i-Screen

Blood test analyzing Natural Killer cell activity and lymphocyte subsets to assess immune function.

Additional Information

This blood test measures various types of lymphocytes, including Natural Killer (NK) cells, which play a crucial role in the innate immune system. It helps identify abnormalities in immune function that may be associated with infertility, autoimmune disorders, and chronic infections. The test provides insights into the balance of different immune cell populations, aiding in the diagnosis and management of various health conditions. Specific benefits include early detection of immune deficiencies and monitoring response to treatment. Key health aspects covered are immune function, infection susceptibility, and autoimmune disease risk.

Biomarkers Tested (9)

Lymphocytes % (%)

Lymphocytes % represents the percentage of lymphocytes, a type of white blood cell involved in immune response, in the total white blood cell count.

CD 19 (/µL)

B cells are responsible for producing antibodies. A decrease in B cell count may indicate immunodeficiency disorders or certain autoimmune diseases.

CD 3 (/µL)

CD3 T cells are a key component of the immune system, and their activation and expansion can occur in response to an infectious agent or an immune-mediated condition.

CD 4 (/µL)

CD4+ T cells, also known as helper T cells, are involved in coordinating immune responses. A decrease in CD4+ T cells may be seen in immunodeficiency disorders, or certain infections. An increase in CD4+ T cell count may be seen in some autoimmune diseases.

CD 8 (/µL)

CD8+ T cells, also called cytotoxic T cells, are involved in directly killing infected or abnormal cells. Elevated CD8+ T cell count may indicate a viral infection, autoimmune diseases, or certain malignancies.

CD 4.8

Natural Killer Cells (/µL)

Natural Killer (NK) play a crucial role in the innate immune system. They are a part of the body's first line of defense against viruses, tumors, and other infected or abnormal cells.

CD 56 (/µL)

CD56 is often used as a marker to identify and characterize NK cells. It helps distinguish NK cells from other lymphocytes, such as T cells and B cells, which may express different surface markers.

CD 16 (/µL)

CD16 cells are involved in antibody-mediated immune responses and play essential roles in immune surveillance, defense against pathogens, and elimination of antibody-bound target cells.
