The usefulness of a muscle biopsy depends on consideration of all the following four criteria:

• choice of muscle;
  
• biopsy technique;
  
• array of histopathology performed.
  

APPROPRIATENESS OF THE TEST

Biopsy is most useful for the diagnosis of:

• Inflammatory myopathies (diagnosis and to monitor treatment).
  
• Certain muscular dystrophies for which the structural abnormality is known but genetic testing is not readily available (where there are many different mutations within the abnormal gene, e.g. the sarcoglycanopathies).
  
• Mitochondrial cytopathies, both to look for the
