1. What is SGOT/SGPT Ratio?

Definition: The SGOT/SGPT ratio (AST/ALT ratio) is a calculated value used in medical diagnostics to assess liver health and differentiate between various liver conditions.

Purpose: This ratio helps clinicians evaluate potential liver damage, with different ratio values suggesting different types of liver disease.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Ratio \) — SGOT/SGPT ratio (dimensionless)
• \( SGOT \) — Serum glutamic-oxaloacetic transaminase (U/L)
• \( SGPT \) — Serum glutamic-pyruvic transaminase (U/L)

Explanation: The ratio is calculated by dividing the SGOT (AST) level by the SGPT (ALT) level from blood tests.

3. Clinical Significance of SGOT/SGPT Ratio

Details: The ratio helps differentiate between:

• Viral hepatitis (ratio typically < 1)
• Alcoholic liver disease (ratio often > 2)
• Cirrhosis (ratio frequently > 1)

4. Using the Calculator

Tips: Enter both SGOT and SGPT values in U/L from blood test results. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are normal SGOT and SGPT levels?
A: Typically 10-40 U/L for both, but ranges vary by lab. Always consult your healthcare provider.

Q2: What does a high ratio indicate?
A: A ratio > 2 may suggest alcoholic liver disease, while > 1 may indicate cirrhosis.

Q3: What does a low ratio indicate?
A: A ratio < 1 often suggests acute viral hepatitis or non-alcoholic fatty liver disease.

Q4: Is this ratio diagnostic by itself?
A: No, it must be interpreted with other clinical findings and tests by a physician.

Q5: Why is it called AST/ALT in some places?
A: SGOT is now called AST, and SGPT is called ALT in modern terminology, but both names are still used.
