IgH Clonality by NGS
Use
The IgH Clonality by NGS test is designed to detect clonal populations of B-lymphocytes in a given patient sample through the analysis of the VDJ segment of the immunoglobulin heavy chain (IgH) gene. Detecting the presence of clonal B-lymphocyte populations is important for the diagnosis of B-cell lymphoma or leukemia. Additionally, this test provides important information on somatic hypermutations in the neoplastic clone as well as tumor heterogeneity. The presence of more than one clone or subclones within the B-cell lymphoma/leukemia cells can also be determined by this assay. The IgH Clonality by NGS test is also useful for monitoring patients with B-cell lymphoma/leukemia due to its high sensitivity and its quantitative nature. Using this technology has been reported to be reliable in monitoring patients with diffuse large B-cell lymphoma (DLBCL) and acute lymphoblastic lymphoma (ALL).
Special Instructions
Use cold pack for transport, making sure cold pack is not in direct contact with specimen. For fresh samples: refrigerate before shipping and ship same day as drawn whenever possible. Do not freeze. Please select extract & hold - DNA if specimen hold service is desired.
Limitations
Note on FFPE: Paraffin block is preferred. Do not use zinc fixatives. If submitting slides, please use positively-charged slides and 10% NBF fixative. Block and slide identifiers should be clearly written and match exactly with the specimen ID and specimen labeling as noted on the requisition.
