This ratio is particularly valuable in determining the cause of liver enzyme elevations. Values above 1 suggest more severe liver damage or alcoholic etiology, while values below 1 indicate less severe damage, typically seen in viral hepatitis or NAFLD. Serial measurements can track disease progression or response to treatment.

The De Ritis ratio, named after Italian physician Fernando De Ritis, is the ratio of AST to ALT enzymes used to evaluate liver disease etiology and severity.
High De Ritis Ratio levels above the standard range may indicate an underlying health condition that warrants further evaluation.
Low De Ritis Ratio levels below the standard range may indicate an underlying health condition that warrants further evaluation.
The De Ritis ratio, named after Italian physician Fernando De Ritis, is the ratio of AST to ALT enzymes used to evaluate liver disease etiology and severity.
Normal and optimal De Ritis Ratio ranges can vary by sex, age, and lab methodology. Review your result with a qualified clinician for personalized interpretation.

Serial measurements can track disease progression or response to treatment.
The ratio itself is asymptomatic. Underlying conditions may present with: right upper quadrant discomfort, fatigue, nausea, loss of appetite, jaundice, spider angiomas, and ascites in advanced disease.
Elevated ratio: Alcoholic hepatitis, cirrhosis (any cause), cardiac muscle damage. Normal/low ratio: Acute viral hepatitis, non-alcoholic steatohepatitis (NASH), drug-induced hepatitis.
De Ritis Ratio can be ordered through Vitals Vault without a doctor referral, then completed at CLIA-certified Quest Diagnostics locations nationwide. After checkout, you receive clear draw instructions, digital requisition details, and a structured report that explains whether your result is in standard range, optimal range, or needs follow-up review.
Start by identifying the root cause, then use targeted nutrition, training, sleep, stress, and follow-up retesting to verify improvement. De Ritis Ratio should be optimized with a personalized plan, not guesswork.
You should speak with a clinician if De Ritis Ratio is significantly outside the reference range, trending in the wrong direction across repeat tests, or accompanied by symptoms like fatigue, chest discomfort, dizziness, weight change, or persistent inflammation signs. Immediate medical care is important for severe symptoms, not just abnormal numbers in isolation.
A practical retesting cadence for De Ritis Ratio is every 8 to 12 weeks after major lifestyle, nutrition, or medication changes, and every 3 to 6 months for stable long-term tracking. Faster cadence is useful when values are clearly abnormal, while maintenance cadence helps confirm durability once results stabilize.
You can compare Essential ($99), Advanced ($199), and Max ($399) plans during checkout to confirm De Ritis Ratio inclusion before purchasing. If De Ritis Ratio is not in your selected tier, you can upgrade plans or add targeted testing so your panel matches your goals, symptoms, and retesting strategy.
De Ritis Ratio is included in our comprehensive biomarker panels, processed at CLIA-certified Quest Diagnostics locations nationwide.
