The "% T Cell" marker refers to the percentage of T cells in the lymphocyte population of the blood. T cells, a type of white blood cell, are central to the adaptive immune response, playing a pivotal role in immune regulation and response to pathogens.
If the T cell percentage is high with normal or low B cells, or if there are normal T cell levels with low B cell counts, it may indicate a T cell dominance (Immunotype 2). This condition can be associated with immune dysregulation, including hypersensitivities, allergies, and certain autoimmune disorders. Conversely, a low % T Cell could suggest issues with bone marrow, lymph nodes, and other lymphoid organs, and is observed in conditions like viral infections, including HIV and COVID-19.
