New test helps identify hepatitis C patients at high risk of developing cirrhosis

...se of individual variability, these factors don't yield a very accurate prediction. A liver biopsy can indicate the amount of damage to the liver up until the time of the biopsy, but can't reveal how much future damage will occur. The new test assessed by Cheung and his colleagues is a way to hedge ...
