Test Name: CD2
Methodology: Flow Cytometry
Staining for CD2 detects normal T-lymphocytes and NK cells. It is also expressed at normal or abnormal levels by most mature T-cell non-Hodgkin lymphomas and precursor T-cell lymphoblastic lymphomas/leukemias. Abnormal CD2 expression also occurs on monocytes in some acute myeloid leukemias and on mast cells in systemic mastocytosis.
Testing for this antigen is typically performed as a part of the leukemia/lymphoma screening panel and the systemic mastocytosis add-on panel. For customized testing panels including this antigen, please contact the Medical Director of the Flow Cytometry laboratory.
