I am talking about the hepatitis B core antibody test.
In December 9, 2006 and February 9, 2007 same result.
(Hepatitis B core antibody) positive
(Hepatitis B surface antigen) Negative
(Hepatitis B surface antibody) Negative

In October 9, 2006 it was all negative!!!!
Did the result will be always positive? Forever?
If yes, do you know any medicine can remove it from the blood temporary for one day to do successful blood examination?
