Understand how therapeutic monoclonal antibodies appear on protein electrophoresis
Learn why daratumumab and isatuximab can complicate the interpretation of myeloma monitoring results.
Impact of monoclonal antibody therapies on electrophoresis interpretation in myeloma patients
This webinar is presented in English.
Abstract
There has been an explosion of monoclonal antibody therapies in medicine in recent years to treat a wide range of conditions, including multiple myeloma. Daratumumab and isatuximab are monoclonal IgG kappa antibodies against CD38, a marker on plasma cells, and are used to treat myeloma. These therapies are given in doses high enough to be detected on routine protein electrophoresis and can confound interpretation of results.
This talk will show how these drugs appear on protein electrophoresis, give examples of cases where they have interfered with result interpretation, and discuss the use of the Hydrashift assays to accurately interpret the results.
What will you learn?
Review practical case studies of assay interference
Explore real clinical examples where therapeutic antibodies affected electrophoretic findings and M-protein assessment.
Discover solutions for accurate result interpretation
Understand the role of Hydrashift assays and other approaches to differentiate treatment-related antibodies from residual disease.
HYDRASHIFT assay moves the drug out of the way so you can see what is left, useful for proving remission but also for detecting relapse
