Webinar presenter Xiaojun Wu, MD, PhD, Assistant professor, Director of Hematopathology Section at NCR of Johns Hopkins Medicine, Department of Pathology, SOM at Johns Hopkins University, discusses how to integrate Kappa and Lambda in situ hybridization testing into your standard hematopathology workflow to accurately assess B-cell and plasma cell clonality. You will also gain the skills to recognize testing pitfalls in challenging reactive versus neoplastic proliferations and apply ancillary tools to resolve complex cases.
This on-demand webinar was originally broadcast on July 15, 2026.
What should you expect to learn from this webinar?
• Integrate Kappa and Lambda in situ hybridization testing into the standard hematopathology workflow to assess B-cell and plasma cell clonality.
• Recognize pitfalls in Kappa/Lambda testing when differentiating reactive from neoplastic plasma cell proliferations, including subtle restriction and unusual staining patterns.
• Apply ancillary tools (molecular, immunohistochemistry, and Dual ISH for K/L stains) to resolve challenging cases beyond light chain analysis.
