I was diagnosed with MM in 2023 by a bone marrow biopsy. My Iga and lambda numbers were very high but my oncologist did not order the test that types the MM, he just confirmed my assumption that I had Iga lambda myeloma. I changed hematologists and she did order further testing and scans that hadn’t been done and said that according to testing I actually had IgG kappa myeloma. She has never explained to me when I’ve asked, how I can have elevated Iga and lambda values and actually be IgG kappa. Has this ever happened to anyone? Does it sound reasonable? I was also diagnosed with kappa restricted Non-Hodgkin Lymphoma later in 2023. Could that skew the results? No one has been able to give me a straight answer. I even paid for a second opinion from Stanford and still it’s vague.
