This protocol describes the pivotal accuracy study for the IdentiClone Dx TRG Assay. The intent of the accuracy study is to demonstrate agreement between the results of the IC TRG Dx Assay and a predicate devise or assay on retrospective and residual de-identified DNA extracted from FFPE (Formalin Fixed Paraffin Embedded) samples from individuals with suspected T-Cell Lymphoproliferations. The predicate device will be the LymphoTrack Dx TRG (FR1/FR2/FR3) Assays - MiSeq (LT Dx TRG-CE-IVD), which is a CE-IVD assay with a similar intended use as the IC TRG Assay on the same sample type.
De-identified, residual FFPE specimens with a minimum of 8 curls
Subject Age ≥ 18

IdentiClone Dx TRG Assay
Diagnostic testThe IdentiClone Dx TRG Assay ("Assay") is an in vitro diagnostic product intended for qualitative capillary electrophoresis based-detection of clonality in T-cell receptor gamma chain (TRG) gene rearrangements in Formalin-Fixed Paraffin-Embedded (FFPE) specimens as an adjunctive method for the diagnosis of T-cell lymphoproliferative disease. This qualitative, non-automated Assay is for use on the ABI 3500xL Dx and ABI 3500xL Genetic Analyzers.
% Agreement
Agreement between the results of the Invivoscribe IdentiClone Dx TRG Assay and the LymphoTrack Dx TRG (FR1/FR2/FR3) Assays - MiSeq by assessing the positive and negative percent agreement between the two assays.
