title: Anti-HBbrno: a new CIEP hepatitis B marker, more sensitive than HBsAg radioimmunoassay.
abstract: Evidence is presented for the new HBbrnoAg-Anti-HGbrno system association with the HBsAg. The association is displayed particularly in a prevalence of Ausria detectable HBsAg carriers among the anti-HBbrno carriers, suggesting the anti-HBbrno to be a marker of contact with hepatitis B or, possibly, an indicator of co-existing HBsAg antigenaemia, not detectable by radioimmunoassay. Identity of HBbrnoAg with HBsAg/a, d, y, w, is ruled out, the identity with the other HBV associated antigenic specificities remaining questionable.
