Am J Emerg Med
. 2014 Mar;
32(6):511-6.
PMID: 24666744
Background: Measurement of pathogen DNA polymerase activity by enzymatic template generation and amplification (ETGA) has shown promise in detecting pathogens in bloodstream infection (BSI). We perform an in-depth analysis of...

. 2013 Mar;
15(3):319-30.
PMID: 23499338
Bloodstream infections (BSIs) caused by bacteria and fungi are associated with significant morbidity and mortality. Currently, blood culture is the gold standard for confirming a suspected BSI, but has the...
