The Immune Cell Function assay measures the increase in intracellular ATP production that occurs in T-lymphocytes within 24 hours of stimulation by antigens or mitogens. 3 Retrospective studies indicate that this ATP level correlates with T-lymphocyte activity and, consequently, cell-mediated immune function 4-6; thus, ATP measurement appears to be a useful clinical indicator of cell-mediated immune function.
