Tissue biopsy with Congo red stain is the gold standard test for the diagnosis of amyloidosis. Biopsy may be taken from an affected organ such as kidney, or from subcutaneous fat or rectal mucosa. There are no established criteria for the diagnosis of familial amyloidosis.
Diagnostic Study of Choice
Study of choice
- Biopsy may be taken from an affected organ such as kidney, or from subcutaneous fat or rectal mucosa.
- The rectal mucosa biopsy is especially sensitive for:
- Biopsy of the affected organ is recommended for patients with limited organ involvement.
- Biopsy from unaffected organs is more sensitive in patients with multi-organ involvement.
Sequence of Diagnostic Studies
The various investigations must be performed in the following order:
- Physical examination
