Understanding Lab Tests for Liver Diseases
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Liver diseases encompass a wide range of conditions that affect the liver's ability to function properly, including hepatitis, cirrhosis, fatty liver disease, and liver cancer. The liver performs many vital functions, including producing proteins, filtering toxins, and metabolizing nutrients. Blood tests are fundamental for diagnosing liver diseases, monitoring liver function, and assessing the severity of liver damage.
Recommended Test
Protein Electrophoresis, with Total Protein and Reflex to IFE, Serum
This comprehensive test evaluates the different types and levels of proteins in the blood, which are primarily produced by the liver. Liver diseases can cause characteristic changes in protein patterns, including altered albumin levels, abnormal globulin ratios, and the presence of abnormal proteins. This test helps assess liver synthetic function and can detect patterns suggestive of various liver conditions, making it a valuable diagnostic and monitoring tool.

Why Blood Testing is Essential for Liver Diseases
The liver produces most of the proteins found in blood and processes many substances that can be measured through laboratory testing. When liver function is compromised, these changes become detectable in blood work, making lab tests invaluable tools for early detection, diagnosis, and ongoing monitoring of liver health.
Understanding Liver Function Through Protein Analysis
Protein electrophoresis separates blood proteins into distinct groups, allowing healthcare providers to identify abnormal patterns that may indicate liver dysfunction. Changes in albumin production, alterations in globulin levels, and the presence of abnormal protein bands can provide important clues about liver health and help guide further evaluation and treatment decisions.
