Article Synopsis
- The study compares the effectiveness of the VersaTREK system to the Bactec9240 system in detecting bloodstream pathogens in patients suspected of having bacterial sepsis.
- The analysis involved 177 blood culture bottles, where Bactec9240 had no false positives and identified 43 positive results, while VersaTREK had 58 positives but 14 were false positives.
- Overall, while the VersaTREK system shows potential advantages such as versatility and lower blood volume requirements, its high rate of false positives raises concerns.
