We evaluated the overall performance of Cobas 6800 BKV test in detecting BK virus (BKV). examined imprecision and compared qualitative quantitative results obtained from Real-Q quantification assay. assessed 88 plasma 26 urine samples collected between September November 2022 patients with infection using The lognormal coefficient variation indicated that inter-assay precision ranged 13.86 to 33.83%. A strong correlation was observed assay for samples. Spearman’s rank coefficients (ρ)...
We established age-group-specific reference intervals for serum anti-Müllerian hormone (AMH) levels in a Korean population and investigated the effectiveness of AMH assay polycystic ovary syndrome (PCOS) diagnosis.We analyzed AMH, follicle-stimulating (FSH), luteinizing (LH) from 1540 women. Subjects were divided into three groups: healthy, benign gynecologic diseases, PCOS. Age-group-specific diagnostic performance estimated.The PCOS group had median level 7.0 µg/L, which was higher than...
The HLA-B*44:345N allele differs from HLA-B*44:03:01:01 by a 19 nucleotide deletion at positions 440 to 458.
Identifying Mycobacterium using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is challenging. We evaluated the performance of MALDI-TOF MS in identifying nontuberculous mycobacteria (NTM) ASTA MicroIDSys system (ASTA Inc., Suwon, Korea) with MycoDB v1.95s and upgraded v2.0-beta databases. tested 124 NTM isolates collected from Ogawa medium at Severance Hospital, Seoul, Korea, between January April 2019. scores were categorized into three groups:...
Appropriate decision-making is critical for transfusions to prevent unnecessary adverse outcomes; however, transfusion in the emergency department (ED) can only be decided based on sparse evidence a limited time window.This study aimed identify factors associated with appropriate red blood cell (RBC) ED by analyzing retrospective data of patients who received at single center.This analyzed associations between appropriateness and sex, age, initial vital signs, an triage score [the Korean...
Abstract Background Tuberculosis (TB) remains a significant global health concern. Accurate detection of latent TB infection is crucial for effective control and prevention. We aimed to assess the performance an interferon-gamma release assay blood test (QuantiFERON-TB Gold Plus [QFT-Plus]) in various clinical contexts identify conditions that affect its results. Methods conducted retrospective analysis 31 000 QFT-Plus samples collected from 26 subjects at tertiary hospital South Korea over...
The present experiment has been conducted to investigate effects of a recirculation zone at multi-slot film cooling system in ramjet combustor. tested model is pre-diffuser typed combustor having due the large expansion duct. directly affects on effectiveness and heat transfer coefficient first two slots system. Results from experiments are divided into flow regions - region boundary layer developing region. In former region, decreases rapidly mixing effect by shear between injected coolant...
taining bone strength [1,2].The plasma calcitonin concentration is relatively high in infants, and decreases rapidly until adolescence, leveling off during adulthood [3].On average, its higher men than women [4,5]. Calcitonin abnormally increases medullarythyroid cancer [6,7].A cut-off of 10 pg/mL most commonly used to differentiate between C-cell hyperactivity diseases (including medullary thyroid cancer) other [8-10].In addition, a follow-up after treatment for useful monitoring recurrence...
Human cytomegalovirus (CMV) transmitted through breast milk poses fatal risks to preterm infants. However, current molecular assay systems often do not accommodate samples. In this study, we evaluated the analytical and clinical performance of measurement procedure CMV load in utilizing Cobas test on 6,800 system. This was enabled by incorporating a simple independent sample preparation before application samples automated Clinical data from electronic medical records were retrospectively...
Abstract Objectives This study aimed to evaluate the analytical performance of cobas 6800 System (Roche Diagnostics) and assess feasibility using whole-blood specimens instead plasma. Methods The EBV test was evaluated. Thereafter, 120 clinical samples were collected compare artus RG PCR Kit (Qiagen). results conducted paired plasma as well 5× 10× diluted compared with those performed whole blood. Results precision acceptable, its linearity confirmed be within range 2.85 6.89 log IU/mL....
