hep b non-reactive, this means nothing, you mean hbsag non reactive (non reactive means negative)
in case yes you don't have hbv but if antibodies hbsab are non reactive (negative) you must make vaccine to be protected from hbv in the fuuture
I have read that on the CDC site HBsAG will be detected in infected person blood's at 9 weeks
and many doctors said its conclusive at 12 weeks
may I ask u where did get that information ( 6 months ) from ??
Is it updated info ?
guidelines are very slow on this and updated every year or two in europe and about 5 years in US
to have updated info you should be able to serach and understand the value of the studies
hbsag can be detected very early but and also other markers but this is not really important if you do something risky you just take vaccine within 48hours or even clever you do vaccine at birth
as to cronic you can tell after 6months/1 year but the most important thing is to make quantitative tests of antigens to consider it cronic or not since many get rid of hbsag even after one year, the bad is these new tests are relatively expensive so us, canada and uk do not use them.
there is much data on hbsg titers from them is easy to predict serconversion
