A friend with RA has had a blood test come back with ”monoclonal proteins” in her recent test, with “light banding” and has been referred to a hematologist. This test can point to all kinds of bad things, but I seem to remember that this also has some significance/connection with RA. Are any of you familiar with this test and/or the RA connection? We’re all scrambling through the research here, but I thought some of you might have some first-hand knowledge.
Thanks for your help!
