A National Quality Control Reference Panel for Hepatitis B Diagnostic Kits has been established. Markers for these standards which were prepared include National Standards for HBsAg and anti-HBs calibrated against WHO International Standards. In addition, Reference Panels for HBeAg, anti-HBe, anti-HBc, anti-HBc IgM and HBV were established and National Requirements set. These panels have been used for the nationwide evaluation of HB kits and for licensing purposes. © 1993 by Academic Press, Inc.
