LOINC display name : Lymphocyte proliferation.anti-CD28.maximum/CD45 FC (Bld);
LOINC long common name : Lymphocyte proliferation.anti-CD28.maximum/CD45 in Blood by Flow cytometry (FC);
LOINC short name : LPT aCD28 max/CD45 NFr Bld FC;
LOINC description : The percent of proliferating lymphocytes stimulated by anti-CD28 (aCD28) out of the
total CD45 cell population. 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.;
