Abstract The first case of coronavirus disease 2019 (COVID-19) in Korea was reported in January 2020. As the secondary transmissions accelerated within the country, the government revised the outbreak alert for COVID-19 from attention to caution. Mid-February, when a massive outbreak was reported from a church in Daegu, our institution initiated testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). More than 300 laboratory tests were performed within the first 2 months, before the number of cases began to decline. Here, we describe our experience

Abstract Automated blood culture systems are widely used in clinical microbiology laboratories to minimize the workload of laboratory personnel and permit fast turnaround times. However, sometimes false positive signals occur due to leukocytosis, presence of fastidious bacteria, or unexplained causes. We experienced false positive signal in a patient with hyperleukocytosis for the first time since the automated blood culture system was introduced

Abstract Background: A bloodstream infection is a life-threatening medical emergency, with a mortality rate of up to 30%. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) can be used to identify pathogens directly from positive blood cultures. Two commercial preparation kits, SepsiTyper (Bruker Daltonics, Germany) and SepsiPrep (ASTA Corp., Korea), and two MALDI-TOF MS systems, MALDI Biotyper Sirius (Bruker Daltonics, Germany)
