Can a leg muscle biopsy diagnose ATTR-wt amyloidosis?

While biopsies are essential for diagnosing amyloidosis, leg muscle biopsies aren't typically mentioned as a standard diagnostic approach for ATTR-wt (wild-type) amyloidosis.

Common biopsy sites include:
* Abdominal fat pad (belly fat)
* Bone marrow
* Inner lip
* Affected organs (heart, kidney, liver, digestive system)
* Rectum

For ATTR-wt amyloidosis specifically, diagnosis often involves a combination of tests. A technetium pyrophosphate (TcPYP) scan is particularly helpful - it can show amyloid deposits in the heart and sometimes confirm ATTR amyloidosis without needing a biopsy at all.

Additional tests help distinguish wild-type from other forms:
* Blood tests to rule out light chain proteins (seen in AL amyloidosis)
* Genetic testing to rule out hereditary ATTR amyloidosis
* Heart function tests like echocardiograms

If you're considering biopsy options, it's worth discussing with your doctor which site would be most appropriate for your specific symptoms and situation.
