Lambda Immunoglobulin Light Chain, technical only
Use
Lambda ISH is an in situ hybridization assay that targets the lambda immunoglobulin light chain on plasma cells or lymphocytes. This assay is used to establish clonality and detect plasma cell neoplasms. As a technical component only, the test does not include a pathologist read, making it crucial for laboratories to pair this assay with appropriate interpretative services.
Special Instructions
Not provided.
Limitations
The test is a technical component only, which means it does not include pathologist interpretations. Interpretation of results must be done separately by a qualified pathologist. Pre-analytical variables in specimen handling, fixation, and storage can affect the quality and readability of in situ hybridization results. Fixatives other than specified 10% NBF or B plus will lead to specimen rejection. Stability of fresh tissues is limited to 72 hours, after which quality may be compromised.
