• The detection of HBsAg in blood serum using immune-enzyme analysis techniques decisively matters both for diagnostics of acute and chronic hepatitis B and screening of donor's blood and its components, controls of persons from risk groups of hepatitis B injection. The making of panels containing wide specter of samples of blood serums with sero-variants and mutant forms of surface antigen of hepatitis B virus widespread on the territory of the Russian Federation is necessary to control analytic and diagnostic sensitivity of test systems for detecting HBsAg. The testing of reagents kits to detect HBsAg using twi panels containing recombinant and native variants of HBsAg, demonstrated that these kits enable to detect various sero-vatriants of HBsAg (ayw2, adw2, ayw3varA, ayw3varB, adrq-) in concentration 0.1-0.01 IU/l and the so called elusive mutant forms of HBsAg of recombinant and native origin (G145R, Q129R, Q129H, Q129L, T143K, T126N, T126S, D144A, M133L, K141E and P142S). At that, the sensitivity can differ during the detection of native and recombinant mutant forms. The results testify the importance of using the panels both with recombinant and native samples containing the mutant forms of HBsAg in evaluation of sensitivity of reagents kits.
