I have tested for hepitites b and its positive so i checked liver there is no demadge ,is there chances of acute hepittites b or chronic hepitites b ?

Need further tests: While Hepatitis B can be very serious, most cases in adults are self-limited. No more than 5% of adults who get Hep B develop chronic Hep B so the odds are good your test indicates past exposure and you will not develop further problems. But get further testing which can confirm that it is not chronic. See http://www.who.int/mediacentre/factsheets/fs204/en/
