An "easy" test for amyloidosis is a fat pad biopsy in which the doctor removes a small bit of fat from a shallow incision in your abdomen. I had one done two years ago due to multiple symptoms that pointed to amyloidosis. Turned out negative. Unfortunately when one collects autoimmune and other diseases (a sucky hobby) it is difficult to determine what is causing symptoms. Then the stress of not knowing hits us, and that makes symptoms worse. Hopefully you can get some answers soon.
