Algorithm

The Chronic Hepatitis B Liver Fibrosis Calculator (CHB-LFC) algorithm is presented on the picture. The flowchart is self-explanatory, however, it is important to clarify the possibility of situation with confounding results, where particular patient may be classified as both positive and negative for significant fibrosis/cirrhosis. In cases where APRI is <0.5 and FIB-4>1.45 or in cases where GUCI is <1.8 and Lok score is >0.65, patient is classified as positive for significant fibrosis/cirrhosis due to a high PPV for positivity thresholds.
