Sensitivity and Specificity of a COVID-19 Lateral Flow Immunoassay Compared to RT-PCR in Pregnant Womenat Arifin Achmad General Hospital Pekanbaru, Indonesia

Comparison of sensitivity and specificity of PCR and sputum smear compared to culture in diagnosis of tuberculosis

Background: Molecular detection has recently been proposed by nucleic acid amplification, known as polymerase chain reaction (PCR). The aim of this study was to compare the diagnostic method of smear and polymerase chain reaction with culture in terms of sensitivity, specificity, positive and negative predictive value in the diagnosis of pulmonary tuberculosis. Methods: In this cross-sectional...

COVID-19 in Nursing Homes: The Problematic Management of Residents Without Positive COVID-19 RT-PCR

Comparing the Diagnostic Power of Chest CT Scan and RT-PCR in Diagnosis of COVID-19

Background and purpose: Proper diagnosis of patients with COVID-19 is one of the challenges in medical centers. RT-PCR is the standard and reference test in diagnosis of patients with COVID-19. This study aimed at accelerating the correct diagnosis of COVID-19 and the diagnostic power of chest CT scan and RT-PCR. Materials and methods: This study was performed in 569 patients with COVID-19 adm...

Rapid Detection of COVID-19 by RT-LAMP PCR Technique and its Comparison with Real-Time RT-PCR Method

Detection of influenza virus using a lateral flow immunoassay for amplified DNA by a microfluidic RT-PCR chip.

Influenza virus RNA was amplified by a continuous-flow polydimethylsiloxane microfluidic RT-PCR chip within 15-20 min. The amplified influenza virus RNA was observed with the naked eye, as the red color at the test line, using a lateral flow immunoassay within 1 min.
