Casandra Test Code QD32273Version 1 (DRAFT)
Performing Lab
T-cell Receptor (TCR) Beta Gene Rearrangement, PCR (91446)
Also known as: T-Cell Receptor (TCR) Clonality
Clinical Use
Order TestUse
This PCR-based assay evaluates T-cell clonality as part of the diagnostic work-up of specimens containing atypical T‑cell populations. It can be used as a stand-alone test, particularly when prior TCR‑gamma gene rearrangement results are inconclusive or inconsistent morphologically or clinically, and additional testing is desired. Combining analysis for TCRG and TCRB gene rearrangements may improve diagnostic sensitivity in T‑cell proliferative disorders.
