What does a high NAFLD fibrosis score indicate?

A higher score suggests a greater likelihood of advanced liver fibrosis, but the result should be confirmed with additional clinical evaluation and possibly imaging or biopsy.

Can I use this calculator without lab test results?

No, the tool requires specific laboratory values including AST, ALT, platelet count, and albumin levels to compute the fibrosis score.

How does this score differ from FIB-4 or APRI?

The NAFLD fibrosis score uses a different combination of patient age, BMI, diabetes status, and liver enzymes, while FIB-4 relies on age, AST, ALT, and platelet count, and APRI focuses on the AST-to-platelet ratio.

Is the NAFLD fibrosis score reliable for all age groups?

The calculator is validated for adult patients with non-alcoholic fatty liver disease, but its accuracy may vary outside the studied age ranges, and results should be interpreted by a clinician.

About this tool

What NAFLD Fibrosis Score Calculator does

The NAFLD Fibrosis Score Calculator is a web-based tool that estimates the degree of liver fibrosis in patients with non-alcoholic fatty liver disease. By entering clinical data such as age, sex, body mass index, diabetes status, and laboratory values (AST, ALT, platelet count, albumin), the calculator produces a fibrosis score that helps assess the risk of advanced scarring and end-stage liver disease. The result provides a quick, formula-based assessment that can indicate whether the disease is likely to be stable or progressing. This Omni Calculator version stands out for its straightforward data-entry layout and the inclusion of contextual explanations alongside the score. While the core formula remains consistent with other fibrosis indices, the site presents the inputs clearly within a single form and offers links to related liver disease calculators, such as MELD and FIB-4, all within the same ecosystem. A prominent disclaimer emphasizes that the output is an estimate and cannot substitute for a professional clinical evaluation.
