Is it possible that your hbs ag and anti hbs could both be positive?
250iu/ml is the end of the range detactable without diluition, i think that you have a report like this:
hbsag >250iu/ml
this means hbsag is not quantified becuase your blood sample was not diluited, so hbsag can be any value higher than 250iu/ml.
so in the end we dont know what hbsag is.ask lab for accurate hbsag quantity in iu/ml, exact number reported like this:
hbsag 2500,99iu/ml
I think my values are 250iu/ml.
it means that if you check hbsag quantity by abbott architect and hbsag is less than 1500iu/ml you can clear hbv once and for all by interferon+tenofovir
on the contrary you will stay infected
