The Chemiluminescence-Linked and Blood Bag With In-Line Filters Analysis (1)
The use of a chemiluminescence-linked universal bacterial ribosomal RNA gene probe and blood bag with in-line filters analysis for the rapid detection of bacterial contamination in white cell-reduced and nonreduced platelets. Because of the rising incidence of bacterial growth and septic platelet transfusions in aging units, platelet storage is currently limited in the United States to 5 days. This approved shelf life of platelets might be altered if methods were devised to rapidly detect infected units and/or to decrease the incidence of bacterially contaminated platelets.
An investigation was conducted on the effect of a prototype blood collection system with an in-line filter for the production of white cell-reduced platelet-rich plasma on the growth of bacteria in platelets prepared from whole blood that had been inoculated with Staphylococcus epidermidis. Additional studies were conducted with a chemiluminescence-linked ribosomal RNA (rRNA) gene probe and with blood gas analysis to identify possible methods for the rapid detection of bacterial contamination. All units were followed for 9 days of storage.
