¨ T-cell clonality
Order Code: 219501
CPT Codes: 81340, 81342, G0452
Indication: Clinical Diagnosis
Required Patient Information: Clinical Diagnosis
Turn Around Time: 7-10 days
Specimen type: Fresh tissue biopsy, paraffin embedded tissue, whole blood
Methodology: Multiplex PCR analysis targeting the V, D and J regions that flank the unique hypervariable antigen-binding region 3 (CDR3) of the TCR beta gene locus (3 multiplex mixes) and the V and J regions of TCR gamma gene locus are used to identify clonal T cell populations. This assay detects 98% of clonal T cell gene rearrangements.
