Overview

The diagnostic study of choice in amyloidosis is tissue biopsy of the affected organ. Congo Red staining will show apple green birefringence of the tissue sample under polarized light, and subtyping of light chains (for light chain amyloidosis) can be done via mass spectrometry. Bone marrow biopsy and organ-specific laboratory measurements are also important ancillary tests.
