We are proud to announce that PhenoPath is now a Quest Diagnostics Company.
Methodology: Flow Cytometry
This two-tube assay includes one tube targeted primarily at mature B cells, and a second tube targeted primarily at mature T and NK cells. This panel is ideal for ruling out lymphoma in any type of fresh material. Both tubes contain nine antibodies (“9 colors”), with a tenth color allowing use of the DNA binding dye DAPI to facilitate exclusion of DAPI-positive dead and dying cells from the analysis. Antigens evaluated in the B cell tube include CD45, kappa, lambda, CD19, C5, CD20, CD10, CD56, and CD38. Antigens evaluated in the T cell tube include CD45, CD2, CD7, CD3, CD34, CD56, CD5, CD4, and CD8. Potential add-on tubes include: • Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL)/ mantle cell lymphoma (MCL) add-on tube • Follicular lymphoma (FL)/Burkitt lymphoma (BL) add-on tubes • Hairy cell leukemia/marginal zone lymphoma add-on tube • CD5-negative B cell therapy add-on tube • CD5-positive B cell therapy add-on tube • Rule out plasma cell dyscrasia tube • B cell versus plasma cell add-on tube • T cell receptor add-on tube • T cell therapy add-on tube • Large T cell therapy add-on tubes • B-ALL add-on tube • T-ALL add-on tube
