B-Cell Gene Rearrangement
Also known as: B-Cell Translocations
Use
B-Cell gene rearrangement testing is used for identifying clonal B cell populations, which are highly suggestive of B cell malignancies. This assay is useful in the diagnosis, staging or monitoring of various lymphomas and other B-cell lymphoproliferative diseases, however, not all clonal populations are malignant. Also, a negative result does not entirely exclude the presence of a clonal B-cell immunoglobulin gene rearrangement. Up to 20% of B-cell lymphoproliferative disorders can be negative by PCR evaluation. So, the results from this test must be interpreted within the context of clinical, morphologic and immunophenotypic findings.
Special Instructions
Specimen handling includes using a cold pack for transport, making sure it is not in direct contact with the specimen. For fresh samples, refrigerate before shipping and ship same day as drawn whenever possible. Do not freeze. Note the need for correct block and slide identifiers matching the specimen ID.
Limitations
Not all clonal B cell populations identified are malignant. Up to 20% of B-cell lymphoproliferative disorders may be negative by PCR evaluation, which means results need to be interpreted in conjunction with other clinical, morphologic, and immunophenotypic findings.
