[Anti-HCV positivity in blood donors].

At the blood transfusion department of the Faculty Hospital in Olomouc in 1992 and 1993 18,293 blood donors were examined and in 70, i.e. 0.38% anti-HCV positivity was found. All positive subjects were subjected to clinical, laboratory and sonographic examination and are checked regularly at the Second Medical Clinic. In none of the patients liver biopsy was performed so far. The clinical, laboratory and sonographic findings provide evidence of liver damage in 15, i.e. 21.4%. In two of them, i.e. in 2.8%, the findings support the diagnosis of chronic active hepatitis; this will be verified by biopsy. The authors consider dispensarization of anti-HCV positive subjects useful. In all examination of RNA HCV however must be made.
