Cirrhosis:

A serious liver condition characterized by irreversible scarring of the liver that can lead to liver failure and death. Alcohol and chronic viral hepatitis (such as chronic HBV and HCV) can cause continuous inflammation of the liver, which can lead to excess scar formation or fibrosis. Scarring results in the loss of liver cells and impairs liver function. 

A condition where scar rissue develops in the lever - to the extent where such scaring becomes extensive and permanent. Cirrhosis interferes with the normal functioning of the liver. PCR: PCR (polymerase chain reaction) is a process used to amplify pieces of the genetic make-up of a cell or virus. The amplified pieces are then detected and the presence of the virus itself can be determined. 

Cirrhosis is a process in the liver that is characterized on biopsy as having scarring and nodule formation. It is thought to occur following the death of many, many liver cells. A simplified explanation is that something hurts the cells of the liver, which then die, leaving a scarred liver. A liver with cirrhosis may be small and shrunken, as in the case of cirrhosis due to hepatitis or excessive alcohol, or it may be very much enlarged, as in the case of primary biliary cirrhosis and biliary atresia. In all cases it is nodular and firmer than it should be. Normal liver is very soft and spongy. A liver with cirrhosis is very firm and hard. The exact cause of cirrhosis is not known.
