LOINC display name : Lymphocyte proliferation.anti-CD28.maximum/CD3 FC (Bld);
LOINC long common name : Lymphocyte proliferation.anti-CD28.maximum/CD3 in Blood by Flow cytometry (FC);
LOINC short name : LPT aCD28 max/CD3 NFr Bld FC;
LOINC description : The percent of proliferating lymphocytes stimulated by anti-CD28 (aCD28) out of the
total CD3 T-cells. The maximum (highest proliferating out of 3 titrations) response
to anti-CD28 is reported. This is a second-level test for assessing lymphocyte (T-cell)
function after lymphocyte proliferation to phytohemagglutinin has been assessed. The
test is used to evaluate patients with impairment in cellular immunity due to primary
or secondary immunodeficiencies and in patients receiving immunosuppressive or immunomodulatory
therapy.;
