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 in conjunction with TCR-gamma PCR studies in order to increase the likelihood of identifying such populations in reactive as well as neoplastic T cell proliferations. TCR-β clonal rearrangements can be identified in both mature and immature T cell lymphomas and leukemias and can aid in the diagnosis of such neoplasms in conjunction with other diagnostic modalities such as histology, immunohistochemistry and flow cytometry.
Organ: Skin & Mucosa
Disease State: Anaplastic Large Cell Lymphoma (Systemic or Cutaneous)
