Could someone with a low fibroscan score still have cirrhosis? if yes then what is the point of test??

To save U a biopsy!: NO test is perfect, but the goal here is to avoid the great risk of liver biopsy, which is the gold standard in determining how much fibrosis (if cirrhosis) is present in an individual's liver. Regarding Fibroscan, fibrosis stage (F0-2) was the only factor to predict significant discordance between liver biopsy & liver stiffness measurement.
