Clinical Significance

The Lymphoid Molecular Profile is intended as an aid in the diagnosis and subclassification of lymphoid neoplasms as well as to identify potential therapies based on the patient's unique molecular drivers. The profile includes analysis of genes known to be recurrently mutated in chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), Richter's syndrome (RS), mantle cell lymphoma (MCL), marginal zone lymphoma (MZL), lymphoplasmacytic lymphoma (LPL), hairy cell leukemia (HCL), follicular lymphoma (FL), diffuse large B-cell lymphoma (DLBCL), Burkitt lymphoma (BL), double-hit lymphoma (DHL), and various T-cell neoplasms.

Specimen Requirements
