My friend, a nurse who didn't report a few "minor" needle sticks over her career, has the same diagnosis. Hepatitis is the most confusing viral illness in the universe!
I was listening to Doctor Radio on Sirius, bonafied doctors, scientists, etc. One show had experts who were attending an international symposium on hepatitis, talk about hepatitis and take calls. The host doctor, and even the experts, admitted it can be very confusing!
You may just be surface antigen positive like my friend. I still don't understand it, but the bottom line is she is fine, she will not die from hepatitis or liver cancer. She didn't even need any extensive tests outside of blood work, no liver biopsy, etc. She gets routine labs once a year, her liver is fine.
I know you are scared. My friend, when she and I, tried to do some research, got scary advise from knowledgeable sources, including doctors, such as, you need to be under the care of a gastroenterologist, you must have a liver biopsy, etc. None of which is necessarily true according to experts.
I can't stop you from being scared. Go to your doctor with a list of questions. Realize you may not understand it all. Even your general practice doctor, if they are honest, may not know all the answers. Ask A LOT of questions before anyone tells you you have to have a liver biopsy. Make sure you are talking to a doctor who is really up to date on hepatitis. (In other words get a second opinion.)
