Blood Drug Testing

how accurate is the blood test for Hepatitis B and C?

Original Blood sample was taken on 20.11.2006 by the Lab. Tests were done for LFT's and ALt was 62. I went to collect the report on 5.12.2006. Doctor then ordered Additional tests for Hep Bs Antigen, Hep B s Antibody and Hep C Antigen. The results were all conclusive and negative. I am just concerned that since they tested the same old blood specimen taken on 20.11.2006, ie around 15 days old, the antibodies and antigen might have vanished from the blood specimen. Does this ever happen?

1. Anything is possible. I would have a new blood sample checked after 2 weeks and then see if it is the same. The second opinion if one of the biggest tools you have in health care.
