Reducing blood culture contamination in the emergency room
Purpose/Objectives: When blood culture contamination in emergency departments is above 3%, it is associated with adverse patient outcomes, inappropriate antibiotic use, and increased hospital costs. In a large, Midwestern, level I trauma hospital, there is a blood culture contamination (BCC) rate …

Implementation Plan to Integrate the Nanosphere Verigene Assay in a High-volume Reference Laboratory and the Anticipated Workflow Benefits to Adopting Rapid Blood Culture Testing
… of the suspected pathogen from a patient blood culture specimen is required for a definitive diagnosis of bacterial septicemia. Reference laboratories are high-volume facilities most often located some distance away from the collecting facility. Given the lengthy work up already required …

Digital amplification for pathogen detection in bloodstream infections from whole blood
… is essential for control and treatment of bloodstream infections. Sepsis, a diagnostic challenge of blood stream infections, causes thousands of deaths each year. The gold standard for detection and identification of microorganisms is blood culture, which can take up to 5 days to yield a …

Development of A Molecular Gram-Stain Assay For The Diagnosis of Blood Stream Infections Associated With Sepsis
… to cost $24.3 billion annually. Currently, blood culture followed by Gram-stain analysis is the gold standard for diagnosing bacterial infections associated with sepsis. This method generates a high rate of false negative results and, in general, requires 20 to 48 hr to provide results. Both …

The impact of fish oil fatty-acids on post-prandial vascular reactivity.
… of vascular reactivity, were taken along with blood samples, at baseline and at 4 hours in order to coincide with the anticipated peak plasma concentration of these fatty acids. These blood samples were utilised for assessment of biomarkers associated with changes in vascular tone and …

Extraction of Leucocidin From Staphylococci and Its Practical Application in the Diagnosis of Septicemia
… phagocytosis after aseptic transfer of whole blood to a suitable liquid media has been a probable source of false negative blood culture results. This idea is due to the fairly high percentage of suspected septicemia patients who have given negative results with many blood cultures. It also …
