There is a new test that now seems to be commercially available for patients taking Darzalex (dara­tu­mu­mab). This test overcomes the immunofixation false positives that are caused by the mono­clonal antibodies found in Darzalex.

See earlier ASH abstract regarding the test:

Caillon, H., et al, "Overcoming the Interference of Daratumumab with Immunofixation Electrophoresis (IFE) Using an Industry-Developed Dira Test: Hydrashift 2/4 Daratumumab," ASH 2016 annual meeting abstract 2063

And here are some more details on the test itself.
