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

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

Rapid antigen and antibody, serological tests, and RT ‑ PCR-based molecular methods are widely used for the detection of microorganisms worldwide. Objectives: This study aimed by Isothermal nucleic acid amplification techniques to detect the covid-19. Methods: In this study, 200 samples of nasopharynx and oropharynx were collected from Jamaran Heart Hospital in Tehran. Covid -19 was exami...

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...

Comparison of patient-collected and lab technician-collected nasopharyngeal and oropharyngeal swabs for detection of COVID-19 by RT-PCR

Background & Objective:  A simple approach to prevent close contact in healthcare settings during the COVID-19 outbreak is to train patients to collect their own nasopharyngeal and oropharyngeal swabs and deliver them to medical laboratories to have them processed. The aim of our study was to c...

Detection of Circulating Tumor Cells in Breast Cancer Patients Using Cytokeratin-19 Real-Time RT-PCR

PURPOSE The roles of circulating tumor cells (CTCs) as predictive and prognostic factors, as well as key mediators in the metastatic cascade, have been investigated. This study aimed to validate a method to quantify CTCs in peripheral blood using a real-time reverse transcriptase polymerase chain reaction (RT-PCR) assay for cytokeratin (CK)-19 and to evaluate the utility of this assay in detect...
