Understanding Lab Tests for Cirrhosis
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Cirrhosis is a late-stage scarring of the liver caused by various forms of liver disease and conditions, such as hepatitis and chronic alcoholism. While the diagnosis of cirrhosis typically involves imaging studies and sometimes liver biopsy, blood tests play a crucial role in assessing liver function, monitoring disease progression, identifying underlying causes, and detecting complications.
Top Recommended Test
Alanine Aminotransferase ALT (formally known as SGPT)
Cirrhosis can cause elevated ALT levels, indicating ongoing liver cell damage. This enzyme test is essential for monitoring the severity of liver inflammation and damage progression.

Why Blood Testing is Essential for Cirrhosis
Blood tests are fundamental for managing cirrhosis as they help evaluate the extent of liver damage, monitor liver function, identify the underlying cause of liver disease, and detect complications such as liver cancer or heart dysfunction. These tests guide treatment decisions and help track the effectiveness of interventions.
Other Relevant Tests
Alpha-Fetoprotein (AFP), Serum, Tumor Marker
AFP levels can increase in response to liver damage and cirrhosis, though levels are usually not as high as in liver cancer. This test helps monitor liver damage progression and screen for potential liver cancer development.

Bilirubin, Direct
Cirrhosis impairs the liver's ability to process bilirubin effectively, leading to elevated levels of direct bilirubin. This test helps assess the severity of liver dysfunction and bile processing problems.

Bilirubin, Total
The liver damage from cirrhosis impairs its ability to function properly, leading to increased total bilirubin levels. This test provides a comprehensive view of the liver's bilirubin processing capability.

Ceruloplasmin
Cirrhosis can result in increased levels of ceruloplasmin, as this protein is produced in the liver and may increase as a response to chronic liver damage. This test helps assess liver synthetic function.

Gamma Glutamyl Transpeptidase (GGT)
Chronic liver disease like cirrhosis can lead to elevated GGT levels. In cirrhosis, liver cells are gradually replaced by scar tissue, which can cause GGT to leak into the bloodstream, making this a valuable marker of liver damage.

Carbohydrate Antigen (CA) 19-9
Liver damage and cirrhosis can cause an increase in CA 19-9 levels. While primarily a tumor marker, elevated levels in cirrhosis patients may indicate liver dysfunction severity.

Hepatitis C Antibody with Reflex to HCV, RNA, Quantitative, Real-Time PCR
Chronic Hepatitis C can lead to cirrhosis over time. This comprehensive test identifies both past exposure and current active infection, which is crucial for determining if Hepatitis C is the underlying cause of cirrhosis.
2907 reviews
Hepatitis Panel Acute, w/ Ref Confirmation
Since chronic hepatitis infections can lead to cirrhosis, this comprehensive panel helps identify various forms of hepatitis that may be the underlying cause of liver damage and scarring.
2907 reviews
CA-125 (Ovarian Cancer Test)
Cirrhosis can lead to elevated CA-125 levels due to the liver's impaired function and associated complications. While primarily an ovarian cancer marker, it can be elevated in liver disease.
2907 reviews
Hepatitis C Viral RNA, Quantitative Real-Time PCR
The presence of HCV RNA indicates ongoing Hepatitis C infection that may be causing or worsening cirrhosis. This test is essential for monitoring viral load and treatment effectiveness.
2907 reviews
B-Type Natriuretic Peptide (BNP)
Cirrhosis can cause fluid buildup and increased pressure in liver blood vessels, leading to heart dysfunction and elevated BNP levels. The liver's inability to regulate fluids effectively can pressure the heart, making this test important for detecting cardiovascular complications.

Understanding Your Results
Test results should always be interpreted by a healthcare provider who can consider your complete medical history, physical examination findings, and other diagnostic tests. Abnormal results may indicate the need for additional testing or specific treatments to manage cirrhosis and its complications.
