Viral hepatitis can be caused by any one of six identified hepatitis viruses ? they are A, B,C, D, E and G. All cause the liver to become inflamed, which interferes with its ability to function normally. All of these viruses cause Liver function test (LFT) abnormalities in the acute phase. These return to normal as the liver recovers and the time range is 2 weeks to 3 months normally. It may be more in the case of weaker/ aged individuals. Depending on which virus causes the hepatitis the blood test report will vary. Hepatitis A (causes acute viral hepatitis- Jaundice) is usually a self limiting disease which resolves without any medication. Diet and rest are the important parts of treating it. The antibody (HAV antibody) is not a routinely done test in India. If the antibody test is done, it can show a positive result for up to a period of about 6 months. The infections caused by Hepatitis B or C are more chronic and dangerous and tests are done to detect them. Certain antibody blood test will show up positive for these two viruses even post cure.
