Among these, 20,231 components (8345 red blood cell concentrates, 5729 platelet concentrates [PCs] and 6157 plasma units) were tested as part of statistical quality control (QC). In addition, 100% bacterial screening was implemented for aphaeresis platelets in November 2019 and for pooled platelets in October 2022 with 17,187 aphaeresis platelets and 36,865 pooled platelets tested by the end of 2024. All pooled platelets were tested using the large\u2010volume delayed sampling (LVDS) method, whereas 9596 aphaeresis platelets were tested using the two\u2010step method (from November 2019 to November 2022) and 7591 using LVDS (from November 2022 to December 2024). BCs were sampled and inoculated into both aerobic and anaerobic culture bottles and incubated at 36\u2009\u00b1\u20091\u00b0C for 7\u2009days.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      As part of the statistical QC, 20,231 BCs (5729 PCs) were tested, resulting in a confirmed contamination rate of 0.09% (0.14% for PCs).
