Próby Wątrobowe — Liver Function Panel

Comprehensive liver function panel covering ALT, AST, GGT, bilirubin, albumin, and total protein. At 99 PLN (~€23), this provides a thorough hepatic assessment. Individual enzymes available from 22 PLN each for targeted monitoring.

The liver function panel evaluates hepatocellular damage, cholestatic dysfunction, and synthetic capacity. ALT (alanine aminotransferase) is the most liver-specific enzyme — elevated ALT indicates hepatocyte damage from fatty liver disease, viral hepatitis, medications, or alcohol. AST (aspartate aminotransferase) rises with liver damage but is also found in cardiac and skeletal muscle, making the AST:ALT ratio diagnostically useful. GGT (gamma-glutamyl transferase) is particularly sensitive to alcohol-related liver damage and biliary obstruction. An isolated GGT elevation with normal other liver enzymes is a common incidental finding in moderate alcohol consumers. Total bilirubin reflects both liver conjugation function and red blood cell turnover. Mild unconjugated hyperbilirubinaemia (Gilbert syndrome) affects 5–10% of the population and is benign but important to identify to avoid unnecessary investigation. Albumin and total protein assess hepatic synthetic function — the liver produces over 90% of circulating albumin. Low albumin suggests chronic liver disease, malnutrition, or protein-losing nephropathy. Non-alcoholic fatty liver disease (NAFLD) affects an estimated 25% of European adults and is the most common reason for elevated ALT in routine screening. This panel provides the baseline assessment needed for monitoring and staging.
