Lymphocyte Clonality Panel, PCR

Test Summary

This assay interrogates simultaneously the immunoglobulin kappa (IGK), the immunoglobulin heavy chain (IGH), the T-cell receptor beta (TCRB) and the T-cell receptor gamma (TCRG) genes by PCR methods based on the BIOMED-2 consensus. This combination assay will be most useful in diagnosing mixed B-cell and T-cell atypical infiltrates and for lineage identification in poorly differentiated or immature lymphoid malignancies.
