T- and B-Cell Quantitation and Lymphocyte Proliferation to
Mitogens Panel
Clinical Information: See individual test IDs.
Useful For: Assessing global T-cell function and quantitating lymphocyte subsets in a single orderable
test. This panel is most helpful when evaluating patients with immunodeficiencies, where quantitative
decreases in T cells can lead to reduced functional mitogen responses. See individual test IDs for
additional information.
Interpretation: Since the presence of lymphopenia, particularly in the T-cell compartment, can reduce
the magnitude of the proliferative response to antigens, it is helpful to perform simultaneous numerical
evaluation of lymphocyte subsets to aid in interpretation of the functional (proliferation) data. See
individual test IDs for additional information.
