Understanding Lab Tests for Biliary Cirrhosis
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Biliary cirrhosis is a chronic liver disease characterized by progressive damage to bile ducts, leading to scarring and impaired liver function. While the definitive diagnosis typically requires imaging studies and sometimes liver biopsy, blood testing plays a fundamental role in monitoring disease progression, assessing liver function, and detecting complications.
Recommended Test
Copper, Serum or Plasma
This test measures copper levels in the blood, which is important because biliary cirrhosis can cause copper to accumulate in the liver and subsequently overflow into the bloodstream. Monitoring serum copper levels helps assess disease progression and the need for copper-reducing treatments, as elevated copper can cause additional organ damage.

Why Blood Testing is Important in Biliary Cirrhosis
Although there isn't a single blood test to diagnose biliary cirrhosis itself, laboratory testing is essential for evaluating liver function, monitoring disease progression, and identifying complications such as mineral accumulation. Regular blood work helps healthcare providers adjust treatment plans and detect problems before they become severe.
Understanding Copper Accumulation
In biliary cirrhosis, impaired bile flow can interfere with the normal excretion of copper through bile. This leads to copper buildup in liver tissue, and as the condition progresses, excess copper can spill into the bloodstream, potentially causing damage to other organs including the brain and kidneys.
