These scores are simplified educational tools derived from population data. They are not diagnostic on their own and must not be used as the sole basis for treatment, surveillance or prognosis decisions.
Educational Disclaimer
FIB-4 and APRI are simplifications and cutoffs vary between guidelines. Real decisions require hepatology or gastroenterology input, imaging, and possibly liver biopsy. Local lab reference ranges and units must always be checked.
