usless wrong and old test which is not quantitative.if it is sold as quantitative it is a fraud, quantitative has a unit iu/ml for quantity and it reflects quantity of infected cells/immune response
the quantity of the virus is useless, you can have no virus at all but many infected cells which can create new virus from a dna template of the virus inside the cells, hbsag can reflect more or less the number of this dna template
