title: Hepatitis B, Hepatitis C and human immunodeficiency virus prevalences among first time blood donors in Istanbul, Turkey, 2004-2011.
abstract: OBJECTIVE
  This study aims to determine the yearly change rates of the HBsAg, anti-HCV and anti-HIV test results and their positivity rates obtained from the 68,393 donors who applied and donated blood for the first time at the Blood Center of the hospital.
  
  
  METHODS
  Using the ELISA method, screening tests were applied to the blood samples obtained from blood donors, and the HBsAg, anti-HCV and anti-HIV positivity rates were calculated at the end of year eight. However, HBsAg and anti-HCV positivities showed a decreased tendency of positivity in years.
  
  
  RESULTS
  A total of 68,393 donations were received within eight years. Seroprevalences for anti-HIV, HBsAg and anti-HCV tests were, respectively 0.01%, 1.54% and 0.38%. HBsAg and anti-HCV positivities showed a decreased tendency of positivity in years.
