Seropositivity Rates of Hbsag, Anti-Hcv, Anti-Hiv and Vdrl in Blood Donors in Eastern Turkey

Abstract

Infections caused by hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency viruses (HIV) remain the leading most important health problems worldwide. Screening tests such as HBsAs, anti-HCV, anti-HIV and VDRL are mandatory tests to look at before transfusion of blood or blood components. In this study, donors who applied to our Blood Center in a nine-year period were retrospectively evaluated with respect to HBsAs, anti-HCV, anti-HIV and syphilis seroprevalence. HBsAg, anti-HCV and anti-HIV were examined by microparticle ELISA system, and syphilis antibodies were screened by a syphilis test device. Of the total 39,002 individuals, 16,601 (42%) were females and 22,401 (58%) were males. HBsAg positivity was found in 2.55%, anti-HCV in 0.17%, anti-HIV in 0.036%, and VDRL in 0.057% of overall donors. As a result, HBsAg, anti-HCV, anti-HIV and VDRL seropositivity rates in donors living in our region were found lower than those in many regions of Turkey. Nevertheless, because there is no screening method to reduce the risk resulting from transfusion to zero, it appears that it is essential to adopt strict criteria in the selection of donors and to avoid unnecessary transfusion. © Turkish Society of Hematology.
