liver damage is also independent to ast-alt and hbvdna undetactable because the virus is present inside the liver and inside the cells.although liver damage is none or much less with hbvdna und today we are finding damaged livers even in these some carriers in inactive phase this is thanks to fibroscan that was not available years ago so it was impossible to check livers of inactive carriers since biopsy was refused
hbsag quantitaive shows the number of infected cells you have in your liver and your immune response.sometimes hbsag is high (infection diffuse throughout the liver) despite hbvdna und, most of the time it is low ininactive carriers
