What does a high Maddrey discriminant function score indicate?

A higher score suggests a greater risk of liver failure or death from alcoholic hepatitis, typically prompting consideration of steroid therapy and urgent medical evaluation.

Can this calculator diagnose alcoholic hepatitis?

No, the tool only calculates a prognosis score based on lab values; a clinical diagnosis requires patient history, physical examination, and additional testing by a healthcare provider.

What are the three variables needed for the Maddrey score?

The calculator requires the patient's bilirubin level, actual prothrombin time, and prothrombin time control/reference value to compute the discriminant function.

Is the Maddrey score used to decide treatment?

Yes, clinicians use the score to determine if corticosteroid therapy or other interventions are appropriate for patients with alcoholic hepatitis, but treatment decisions always involve a full clinical assessment.

About this tool

What Maddrey's Discriminant Function Calculator does

Maddrey's discriminant function calculator estimates the prognosis of alcoholic hepatitis by analyzing three blood test results: bilirubin level, prothrombin time, and prothrombin time control. Users input these values to receive a score that indicates the likelihood of liver failure or death. The tool is designed for healthcare professionals and researchers managing patients with alcoholic hepatitis, providing a quick numerical assessment based on established medical criteria. It also includes educational context about the condition, its symptoms, and the importance of alcohol cessation. While the calculation itself is straightforward, the site anchors the result in clear explanations of what the score means for patient outcomes. Compared to other liver disease calculators on the same platform, this tool focuses specifically on alcoholic hepatitis prognosis using a historically validated formula, offering a dedicated interface rather than a general health dashboard. It distinguishes itself by presenting the three required variables side-by-side with immediate score output, alongside concise disease background information directly on the calculator page.

Ast Alt Ratio Calculator6 options

Calculates the AST/ALT ratio, a common clinical marker used to assess liver health by comparing serum levels of aspartate transaminase (AST) and alanine transaminase (ALT). Users input their respective numerical values into the dedicated fields, and the tool instantly computes the resulting De Ritis ratio. The platform presents this calculation within an interface designed with clinical-style insights, providing a quick reference point for understanding the relationship between these two enzymes. Healthcare professionals, students in medical fields, and individuals monitoring liver function utilize this calculator to interpret blood work results. It offers a systematic way to determine if the ratio falls into common patterns associated with specific types of hepatic stress or disease.

APRI Calculator

Calculates the Aspartate Transaminase to Platelet Ratio Index (APRI) using user-provided laboratory values for aspartate transaminase (AST) and platelets. This ratio index provides a quick, non-invasive estimate of potential liver fibrosis or cirrhosis risk based on standard clinical measurements. The tool takes two key inputs, AST and platelet count, and processes them through the established formula to yield a single numerical score that helps gauge the severity of liver scarring. Medical professionals and clinicians utilize this resource to assess patient liver health efficiently during routine evaluations. By providing an immediate calculation of the APRI score, it assists in preliminary risk stratification when detailed imaging or biopsy results are not immediately available.
