Hepatitis B is a serious disease of liver caused by Hepatitis B virus. The virus spreads from person to person through blood contact by any means. When it develops for the first time in adulthood, people usually develop Jaundice (acute Hepatitis B).

What are the tests for Hepatitis B? — Hepatitis B infection or its extent of damage to the liver can be diagnosed by routine blood investigations, viral markers including its DNA estimation and ultrasound.
Some people might need fibroscan or a liver biopsy.
How is Hepatitis B treated? — Most people with acute hepatitis B do not need treatment, and most of the patient can get rid of virus by body own defense mechanism ("immune system").
If someone has chronic hepatitis, doctor might suggest taking medicines (antivirals). However, not everyone with chronic hepatitis B needs treatment at the time of diagnosis, but they will need regular monitoring. This involves doing routine blood tests and ultrasound. If the tests show that the virus is doing more damage to the liver medicines can be started at that time.
