This presentation provides a comprehensive overview of the major liver enzymes that are clinically important in evaluating liver function and diagnosing liver-related diseases. It explains how enzymes such as Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST) act as markers of hepatocellular injury, while Alkaline Phosphatase (ALP) and Gamma-Glutamyl Transferase (GGT) are primarily associated with cholestasis and biliary tract obstruction. The content also highlights the relevance of Lactate Dehydrogenase (LDH) and 5’-Nucleotidase (5’NT) in differentiating liver damage from bone and muscle disorders.
The presentation discusses where these enzymes are found in the body, the biochemical reactions they catalyze, how they respond to different liver disorders, and their interpretation in routine laboratory testing. Special focus is given to how patterns of enzyme elevation help distinguish between viral hepatitis, alcoholic liver disease, metabolic conditions, obstructive jaundice, and systemic disorders.
Additionally, the presentation explains the clinical value of monitoring liver enzymes for early disease detection, assessing disease progression, evaluating treatment effectiveness, and identifying drug-induced liver injury. Overall, this presentation serves as a useful resource for medical students, laboratory professionals, and healthcare practitioners wanting to understand the diagnostic significance of liver enzymes in clinical practice.
