Hello Collin,
I fully understand the anxiety and apprehension you are feeling. Although the radio does look high, one of the things you will read or hear about is that MM is so individual that one person’s results should not to compared to another. When I started, I underwent MRI, CAT Scan, Bone Marrow, Bence Jones (yes all these test) to get properly diagnosed. I am a Light Chains patient (not paraprotein) and in the beginning (August 2018) it was 1122mg/l. After initial treatment we got it down to 116mg/l. The thing to look out for with light chains is the ratio.
Good that you are having the bone marrow soon. One step at a time, and you will find a rich source of information and helpful support here.
Have a good weekend.
