Liver Biopsy and Its Diagnostic Value in Wilson’s Disease
Liver biopsy remains one of the most definitive diagnostic tools for Wilson’s disease, particularly in cases where non-invasive tests produce inconclusive results. The procedure allows direct measurement of copper concentration within liver tissue.
In patients with liver-predominant disease, biopsy can confirm excessive copper accumulation even when blood or urine tests are borderline. It also provides valuable information about the extent of liver damage, including inflammation, fibrosis, or cirrhosis.
Histological examination may reveal fatty changes, cellular injury, and fibrosis patterns consistent with copper toxicity. These findings help assess disease severity and guide treatment planning.
Despite its diagnostic value, liver biopsy is invasive and not without risk. Therefore, it is typically reserved for complex cases or when diagnostic uncertainty persists. Advances in non-invasive testing have reduced reliance on biopsy, but it remains an important option in specialized care.
When performed appropriately, liver biopsy offers clarity and confidence in diagnosis, supporting timely and effective management of Wilson’s disease.
