Evaluation of incidence of biological markers for A and B hepatitis]

Fifty employees of the hospital laboratories were examined for the markers of non-A, non-B hepatitis infection. Immunoenzymatic tests of Abbott Diagnostic Division were used for this purpose. Anti-HAV antibodies were diagnosed in 68% of the examined persons, i.e. with an incidence similar to that in the general population. HBV markers were found in 50% of the examined persons, i.e. a few times more often than in the Polish general population. HBsAg carriers constituted 2% of this group. In the remaining persons with anti-HBV antibodies various combinations were found. Most frequent were anti-HBe+, anti-HBc+ and anti-HBs+.
