Fibrosis 4 Score
The Fibrosis 4 score is a non-invasive scoring system based on several laboratory tests that help to estimate the amount of scarring in the liver. This score has been studied in liver disease due to Hepatitis C and NASH.
( Age x AST ) / ( Platelts x ( sqr ( ALT ) )
Explanation of Result :
For NASH : Fib4 score < 1.30 = F0-F1Fib4 score > 2.67 = F3-F4
For HCV with or without HIV : Fib4 score < 1.45 = F0-F1Fib4 score > 3.25 = F3-F4

Liver biopsy has long been an important tool for assessing the degree of liver fibrosis. Information on the presence and degree of liver fibrosis is useful before making therapeutic decisions or predicting disease outcomes. The need to stage liver fibrosis, however, should decrease as treatment options become more successful (as has occurred with viral hepatitis). In recent years, noninvasive tests have demonstrated a reasonable ability to identify significant fibrosis, cirrhosis in particular, nor is it surprising that liver disease specialists and patients favor a noninvasive approach. However, only those tests with the highest diagnostic accuracy, cost-effectiveness, and availability should be implemented. Apart from their diagnostic acc [...]
