I just came back from seeing the Oncologist at my cancer center. I got my IV Actemra and blood work. My IgG and Free Light Chains, both Lambda and Kappa are significantly elevated even though the ratio is still ok. He is concerned and retested today. He is sending all of this to my Rheumatologist and wants some kind of note back. He has also ordered a bone marrow biopsy. I had one 12 years ago, but he thinks I need another one. He isn't convinced this is just non-specific inflammation. They may stop my Actemra. My MTX was already stopped.
I hate RA.
Hope you got some good news.
