  • The test is intended for healthcare professional use only. HBsAg consists of lipid, carbohydrate and protein.
  • The protein moiety of HBsAg contains several poly peptides. The antigenic determinants on the protein moiety of the HBsAg determine the specific characteristics of the different sero types of the virus and is the basis of the immunoassay.
  • The antigenic reactivity of HBsAg is also associated with the surface of spherical or tubular particles. HBsAg is a fragment of the viral lipoprotein capsid.
  • HBsAg test is an antibody sandwich immunoassay. Colloidal gold conjugated monoclonal antibodies reactive to HBsAg (sAb-Au) are dry-immobilized onto a nitrocellulose membrane strip.
