What blood test show amyloidosis?

None: Amyloidosis is not diagnosed by blood tests. It is diagnosed by biopsy of appropriate tissue. Anemia, a high platelet count or an elevated serum alkaline phosphatase may occasionally be associated with amyloidosis but these are not specific for the diagnosis.

No blood test: There is no blood test to detect amyloidosis. Sophisticated laboratory techniques called electrophoresis or free light chain assays may reveal early evidence of some amyloid proteins. A biopsy is needed to confirm a diagnosis of amyloidosis and determine the specific type of protein involved in the disease.

Biopsy: Rather than blood test often required. Blood protein electrophoresis or light chains may suggest it as a possibility
