| Additional information | This assay is useful for establishing clonality of T-cell receptor gene rearrangement for the diagnosis of T-cell lymphoid neoplasms and identification of minimal residual disease or early recurrence in patients with previous diagnosis of T-cell neoplasm. This test was developed and its performance characteristics determined by Quest Diagnostics-Nichols Laboratories. It has not been cleared or approved by the U.S. Food and Drug Administration. The FDA has determined that such clearance or approval is not necessary. |
