I’ve been on Darzalex/Revlimid/Dexamethasone for the last year and a half. I just received the latest Myeloma labs, and my M-Spike is down to 0.11. Serum immunoelectrophoresis identifies it as type IgG.kappa. All past M-Spikes were IgG.Lambda. I wonder if the IgG.kappa M-Spike is from the Darzalex, (a Kapa monoclonal protein) and that the IgG.Lambda M-Spike may be gone. Anybody experience this?
If you’re M spike is that low. That sounds good to me
just prayed 4u gailpricard3 an will continue
Hi @A MyMyelomaTeam Member Daratubanumb can cause a false positive IGG Kappa M spike. Some labs can differentiate this as being therapeutically caused. A special test has to be run to determine this.
