Test Name: T-cell receptor alpha/beta
Methodology: Flow Cytometry
Staining for TCR alpha/beta highlights the majority (>95%) of normal mature CD3+ T-cells in bone marrow and peripheral blood samples. TCR alpha/beta is also expressed on many subtypes of mature T-cell non-Hodgkin lymphomas and in a small subset of post-thymic T-cell lymphoblastic lymphoma/leukemia.
Testing for this antigen is typically performed as a part of the T-cell neoplasm add-on panel. For customized testing panels including this antigen, please contact the Medical Director of the Flow Cytometry laboratory.
