Reliable Detection of T-Cell Clonality by Flow Cytometry in Mature T-Cell Neoplasms Using TRBC1: Implementation as a Reflex Test and Comparison with PCR-Based Clonality Testing

Abstract

Incorporation of the TRBC1 antibody using statistically derived cutoff points in a reflex setting for the evaluation of a suspected T-cell neoplasm improves the identification of clonal T-cell populations by flow cytometry and correlates well with molecular methods.
