10 calculators
Hepatology and gastrointestinal calculators for liver disease severity, GI bleeding risk, hepatic fibrosis estimation, and transplant listing. Tools include the MELD and MELD-Na scores for liver transplant prioritisation, Child-Pugh and ALBI scores for liver function assessment, APRI and FIB-4 for non-invasive fibrosis estimation, and the NAFLD Fibrosis Score for steatohepatitis risk stratification. GI bleeding tools cover the Glasgow-Blatchford Score for pre-endoscopy triage and the Rockall Score for post-endoscopy rebleeding risk. The Maddrey Discriminant Function helps identify alcoholic hepatitis patients who may benefit from corticosteroid therapy, and the SAAG classifies ascites aetiologies. MELD scores are recalibrated periodically; always verify which version your institution uses.
Every tool in this domain is linked below, each with its own formula, inputs, and interpretation notes. Starting from the clinical area instead of the subject? The same calculators are grouped on the specialties pages, the full alphabetical list collects everything in one place, and the comparison tool lines up three tools side by side.
AST to Platelet Ratio Index (APRI) for estimating liver fibrosis and cirrhosis.
GastroenterologyNon-invasive score used to estimate liver fibrosis in chronic liver disease.
GastroenterologyPredicts the need for intervention or mortality in patients with upper gastrointestinal bleeding.
GastroenterologyPredicts severity and prognosis in alcoholic hepatitis.
GastroenterologyModel for End-stage Liver Disease (MELD) score for predicting 3-month mortality in patients with advanced liver disease.
GastroenterologyModel for End-stage Liver Disease Sodium (MELD-Na) score for predicting 3-month mortality in advanced liver disease.
GastroenterologyNon-invasive score used to estimate advanced fibrosis in patients with NAFLD/MASLD.
GastroenterologyPredicts mortality and risk of rebleeding after upper gastrointestinal bleeding.
GastroenterologyCalculates the gradient between serum albumin and ascitic fluid albumin to classify ascites as portal hypertensive (SAAG ≥1.1 g/dL) or non-portal hypertensive (SAAG <1.1 g/dL). First-line diagnostic tool for ascites workup.
Internal MedicineObjective prognostic assessment of liver function using serum albumin and bilirubin. Primarily validated in hepatocellular carcinoma (HCC) for stratifying prognosis and guiding treatment decisions.
