Objective: Reverse transcriptase loop-mediated isothermal amplification (RT-LAMP) is one of the time-saving, accurate, and cost-effective alternative methods to real-time polymerase chain reaction (RT-PCR). This study aimed identify robustness a colorimetric RT-LAMP assay kit that we developed, detecting SARS-COV-2 viral RNA within 30 minutes using primer set special N gene against RT-PCR, gold...

Real-time reverse transcription polymerase chain reaction (RT-PCR) tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are occasionally repeated when clinicians suspect false-negative results, but the conditions under which RT-PCR testing is warranted remain unclear. We evaluated practice of repeat SARS-CoV-2 in 45 patients who were retested after an initial negative PCR test...

The disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in Wuhan, China, December 2019, has rapidly spread worldwide. SARS-CoV-2 is usually detected via real-time reverse-transcription polymerase chain reaction (RT-PCR). However, the increase specimen load institutions/hospitals necessitates a simpler detection system. Here, we present an ultra-rapid, RT-PCR assay for...

PurposeCurrent polymerase chain reaction (PCR) methods for the diagnosis of infections are time consuming and require large sample volume skilled technicians. We developed a novel, easy-to-use, rapid (processing time, 1 minute; total 33 minutes) multiplex real-time PCR test (Direct Strip PCR) that did not DNA extraction to detect 9 pathogens could cause uveitis in 20-μl samples.DesignMulticente...
