AST vs Direct Bilirubin: Key Differences Explained
Compare AST and Direct Bilirubin to learn which marker is more relevant for health assessment.
Why Compare AST and Direct Bilirubin?
Comparing AST and Direct Bilirubin is crucial because they are often used to assess similar yet distinct health conditions. Understanding their differences helps in selecting the right test and interpreting the results accurately.
AST vs Direct Bilirubin: Which Biomarker Matters?
AST and Direct Bilirubin are essential biomarkers used to evaluate different health conditions. Knowing when and how to interpret these biomarkers can significantly impact clinical decision-making.
Quick Comparison Table:
Biomarker | Purpose | Ideal Range | When to Test | Key Differences |
|---|---|---|---|---|
Purpose of Ast not available | Ideal range for Ast not available | Test indications for Ast not available | Key differences for Ast not available | |
Measures conjugated bilirubin | 0.0-0.3 mg/dL | Suspected cholestasis | Reflects conjugated hyperbilirubinemia |
Key Takeaways:
AST tracks injury inside liver cells; direct bilirubin points to bile duct issues.
High direct bilirubin may indicate bile backup, even if AST is mildly raised.
These help pinpoint obstructive vs. inflammatory liver problems.
