Analytical evaluation of newly developed presepsin by a Sysmex HISCL-5000 (Sysmex, Japan) automated immune analyzer was performed.For evaluation, sepsis patient samples were collected before treatment in an emergency department. Precision, linearity, limit blank/limit detection, method comparisons, and reference intervals evaluated. Method comparisons performed using PATHFAST (LSI Medience Corporation, Japan).Precision 20x2x2 protocol for low (306 pg/mL) high (1031 levels resulted...

The analytical performance and clinical application of measuring insulin connecting peptide (C-peptide) by point care (POC) assay were evaluated. A POC system (SelexOn, Osang Healthcare Inc., Anyang-si, Korea) was evaluated for precision, linearity, limit blank (LOB), detection (LOD). Method comparison performed with the Cobas Elecsys C-peptide (Roche Diagnostics GmbH, Mannheim, Germany) using 215 201 patient specimens C-peptide, respectively. For application, resistance indices studied....

Serology testing is useful to determine the past infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).We evaluated comparative performance of a newly developed neutralizing antibody test (R-FIND SARS-CoV-2 Neutralizing Antibody ELISA, SG Medical, Seoul, Korea) and rapid fluorescence immunoassay (FREND™ COVID-19 SP, NanoEntek, Hwaseong, for detection spike protein antibody. They were compared cPass™ Neutralization Detection Kit (Genscript Biotech, Piscataway, NJ, USA)...
