Lymphocyte Subset Panel

A lymphocyte subset panel is a laboratory test that measures the levels of different types of lymphocytes in the blood. Lymphocytes are a type of white blood cell that play a key role in the immune response.

The main types of lymphocytes that are measured in a subset panel include: 1. T lymphocytes (T cells) - These lymphocytes are responsible for cell-mediated immunity and can be further divided into subsets such as CD4+ T cells (helper T cells) and CD8+ T cells (cytotoxic T cells); 2. B lymphocytes (B cells) - These lymphocytes are responsible for producing antibodies and are important for the humoral immune response; 3. Natural killer (NK) cells - These lymphocytes are responsible for killing infected cells and tumor cells.

The lymphocyte subset panel can help identify immune deficiencies, autoimmune diseases, and monitor responses to treatments for conditions such as HIV/AIDS, leukemia, and organ transplantation.

The results of the panel are typically reported as percentages or absolute numbers of each lymphocyte subset. Abnormal levels of specific lymphocyte subsets can indicate underlying health issues that may require further evaluation and treatment.
