Very welcome. My M-spike hovers between 0.7 and 0.9. I am not a healthcare professional, but my job required me to establish affiliation agreements with healthcare facilities so I was constantly in and out of doctor's offices and hospitals. I began to feel a general feeling of malaise over the course of about three months which was unusual as I had been working in this capacity for almost a decade and I had never felt that unwell before. I just dismissed my symptoms and figured it would pass. It wasn't until I was stricken with bilateral pneumonia and my blood counts were low that I knew something was wrong. Physicians also felt something had gone awry as I was only 35 years old. I was referred to a rheumatologist who ran a battery of tests. Dr. Smith found the elevated IgA levels. She then provided a referral to an oncologist/hematologist who ordered more blood tests. The abnormal Kappa Free Light Chain test prompted the BMB.
