Amyloidosis, all my symptoms , heart, liver high ggt, brain, neurological, gasrto and urinary, lungs. gfr not released, what is the genetic blood test?

Self-diagnosis?: Amyloidosis can mimic anything. It's not especially treatable so there's no hurry diagnosing it. Ask about a serum protein electrophoresis and urine test for Bence-Jones for amyloid AL. Amyoid AF is a neuropathy / pain syndrome and I wouldn't waste the money. Amyloid AA labwork isn't specific; it's rare in the absence of leprosy etc. I'd have a fat biopsy -- maybe you actually do have it.
