What is T- Cell Receptor (TCR-B) Gene Rearrangement?
This specialized test examines the genetic makeup of T-cells, a type of white blood cell crucial for your immune system. It looks for specific changes, called rearrangements, in the T-cell receptor beta (TCR-B) gene within a tissue sample. These rearrangements can indicate whether a group of T-cells is clonal, which is important for diagnosing certain conditions.
Why is this test important?
This test is primarily used to diagnose and classify T-cell lymphomas and leukemias, which are cancers of the T-cells. It helps differentiate between reactive (non-cancerous) T-cell proliferations and malignant (cancerous) ones, guiding appropriate treatment strategies and monitoring disease progression.
How to Prepare
No special preparation required. The tissue sample is typically collected during a biopsy procedure.
