Decode your liver health with advanced AI intelligence. Comprehensive analysis of ALT, AST, and liver enzyme function with enterprise-grade precision and clinical insights.
Understanding ALT/AST Liver Enzyme Analysis
A comprehensive hepatic assessment that provides critical insights into your liver's cellular integrity and metabolic function
The ALT/AST Liver Enzyme Analysis represents a sophisticated hepatic diagnostic approach that evaluates your liver's cellular integrity through the measurement of transaminase enzymes. This comprehensive analysis examines Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST) levels to provide essential insights into liver function, cellular damage, and overall hepatic health.
Healthcare providers utilize ALT/AST analysis data as a cornerstone for diagnosing liver disease, monitoring treatment efficacy, and assessing hepatic function. The analysis enables identification of conditions such as hepatitis, cirrhosis, fatty liver disease, and drug-induced liver injury, while also providing insights into overall liver health and metabolic status.
This hepatic evaluation is essential for patients experiencing symptoms related to liver dysfunction, including jaundice, abdominal pain, fatigue, dark urine, or signs of liver disease. Additionally, ALT/AST monitoring is crucial for individuals with liver disease, those taking medications that affect liver function, and patients undergoing treatment for conditions that impact hepatic metabolism.
Clinical Significance
ALT/AST analysis serves as a fundamental diagnostic tool in hepatology, providing essential insights into liver cell integrity and function. Elevated levels can indicate liver damage, inflammation, or disease.
Testing Indications
Key ALT/AST Liver Enzyme Parameters Analyzed
Comprehensive analysis of essential liver enzyme markers for complete hepatic function assessment
ALT
Alanine Aminotransferase
Liver-specific enzyme marker
Clinical Significance
Primarily found in liver cells. Elevated levels indicate liver damage, hepatitis, or liver disease. More specific to liver than AST.
AST
Aspartate Aminotransferase
Multi-organ enzyme marker
Clinical Significance
Found in liver, heart, muscle, and other tissues. Elevated levels may indicate liver damage, heart attack, or muscle injury.
ALT/AST Normal Reference Ranges
Standard reference ranges for liver enzyme parameters in healthy adults
| Parameter | Normal Range | Units | Clinical Significance |
|---|---|---|---|
|
ALT
|
M: 7-56
F: 5-36
|
U/L | Liver-specific enzyme marker |
|
AST
|
10 - 40 | U/L | Multi-organ enzyme marker |
