Abstract
In the organ donation process, screening for serologic markers for a selection of agents is essential to prevent infection transmission. The screening of donors for specific potential infections can never absolutely exclude the risk of transmission. For reevaluation of serology tests, we analyzed results of tests requested for all brain-dead donors. Our study included all actual brain-dead donors who were seen from January 2017 to February 2018, received ancillary tests, and had final confirmation of brain death at our organ procurement unit. Most candidates for organ and tissue donation were seronegative for intended agents. We found that 14.4% of the samples were suspicious for infectious and needed further evaluation; 12.2% of donors had positive results corresponding to hepatitis B, and only 1.9% were rejected from donation. Requisiteness to DNA detection for hepatitis B virus infection was mainly related to age over 50 years. The process of donor screening must systemically assess the donor. At the final stage, essential biomarkers must be investigated. Application of more caution in evaluation of older donors, including more screening tests before transfer to the operating room, remains mandatory.
