Welcome to Connect @3419harrison, AL Amyloidosis is a disease which occurs when a protein called amyloid builds up in organs This amyloid buildup can make the organs not work properly and can affect the heart, kidneys, liver, spleen, nervous system and digestive tract.
If your doctor is suspecting your kidney is impacted, that may be why they suggested a kidney biopsy. It would allow them to test the tissue to see what type of amyloid is involved

Two members who have kidney involvement with amyloidosis are @sherryzitter and @peggyjean. They both make reference to having kidney biopsies. I’m going to tag them in hopes that they may be able to give you some more information related to the biopsy and whether you may want to reconsider the decision not to have it done.

What type of therapy has your doctor ordered for you?
