Abstract
The relationship between the ALT value of blood donors and incidence of post-transfusion hepatitis was investigated. One hundred eighty-seven recipients received only single component of blood of which the ALT value of donor was investigated without any exception. The recipients received 1148 units of blood within 7 days for the first time. Twenty-five recipients (13.4%) received at least one unit of high ALT blood (donor ALT>26 KU). These recipients shared 9% of non-hepatitis patients, 19% of hepatitis patients. The share in hepatitis patients of high ALT recipients was significantly higher than the share in non-hepatitis patients. The incidence of post-transfusion hepatitis may decrease using the bloods whose donor ALT were below 25 KU only.
