Patients receiving any kind of human blood preparations are in permane
nt danger of any infection including hepatitis C (HCV) infection. Test
ing for the presence of HCV in blood preparations is one of the steps
towards safe medical treatment, One of the approaches for this testing
is a detection of HCV nucleic acid. In this paper we describe a simpl
e method for isolation of HCV RNA from blood preparations and control
of HCV RNA presence in 19 intravenous and intramuscular products, manu
factured in the National Blood Transfusion Institute in Belgrade. RT-P
CR was performed according the rules saving RNA. Primers were located
in 5' conserved region. Seven out of 19 batches of gamma-globulin, alb
umin, anti-tetanus and anti-rabies immunoglobulin preparations were fo
und to be HCV RNA positive. For the time being, the PCR method is too
expensive for routine HCV RNA testing of hundreds of;blood donors per
day. Serological screening test of blood donors and nested PCR testing
for HCV RNA. in blood preparations could be an efficient combination
of tests in prevention of posttransfusion hepatitis C. (C) 1998 Elsevi
