FIB-4 Calculator
FIB-4 Calculator
What is the calculator for and who produced it?
The Fibrosis-4 index (FIB-4) is used as a non-invasive tool for the presence of advanced liver fibrosis in metabolic dysfunction associated steatotic liver disease and type 2 diabetes
How should it be used?
NICE advises not to use liver function tests to monitor patients with Non Alcoholic Fatty Liver Disease (NAFLD) but use either FIB-4, NAFLD or ELF to estimate the risk of liver fibrosis.
The calculator requires coded AST, ALT, and platelet values in the record. These can be added on the template prior to pressing the Calculate button. EMIS will return an error if any value is missing.
This FIB-4 calculator will not work on patients aged 35 or under, and will return an error.
Interpretation of score
A score of greater than 2.67 suggests advanced liver fibrosis. Patients at high risk of advanced liver fibrosis should be referred to a hepatology specialist for further assessment and management.
