RT Journal Article SR Electronic T1 Bacterial contamination of platelet concentrates stored at 20°C JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 401 OP 404 DO 10.1136/jcp.26.6.401 VO 26 IS 6 A1 Margaret Cunningham A1 John D. Cash YR 1973 UL http://jcp.bmj.com/content/26/6/401.abstract AB Qualitative and quantitative data on the bacterial contamination of 1000 platelet concentrates prepared and stored at 20°C are presented.
