The rapid antigen tests for SARS-CoV-2 are quick, widely available, and inexpensive. Rapid antigen tests have gradually replaced the time-consuming and costly RT-PCR. Currently, although several RAT kits have been extensively used for the diagnosis of COVID-19, validity data are limited due to the inconsistent sensitivity and poor reproducibility. Meanwhile, WHO does not recommend specific commercial RAT kits. Therefore, it is crucial to establish a method to evaluate the effectiveness of different rapid antigen tests kits. This study aimed to develop an evaluation system for rapid antigen tests to provide an efficient and accurate technique for screening SARS-CoV-2 antigen detection kits. Given large number of rapid antigen tests kits available, this study only focused on those that are representative and commonely used in China. By minimzing biases through randomization, concealment, and blinding, we eventually found that the Test 1 had the lowest sensitivity and the Test VI had the highest sensitivity. This study provided an evaluation platform that can potentially serve as a reference for COVID-19 diagnostic strategies.</p> 2024-01-12T00:00:00+08:00 Copyright (c) 2024 Minghang Yu, Yang Xiong, Pu Liang, Danying Chen, Yuting Zhang, Huan Liu, Yuanyuan Zhang, Xuesen Zhao, Ronghua Jin, Xi Wang Development of an In Situ Hybridization Method for Detection of Akabane Virus 2023-12-25T02:49:05+08:00 Nihat Toplu Tuba Çiğdem Oğuzoğlu Ayşe Nur Akkoç <p>Akabane virus (AKAV) is an arbovirus belonging to the family Bunyaviridae, genus Orthobunyavirus. AKAV consists of three-segment (L, M, and S RNA segments), negative single-stranded RNA. The aim of this study was to investigate an in situ hybridization method (ISH) in a Vero E6 cell line infected with Akabane virus. The 320 base pair amplicon was obtained by RT-PCR with a primer pair and labeled with digoxigenin. Akabane virus RNAs were seen as a granular pattern in the cytoplasm of infected cells. As a result, the expression of the particular Akabane virus gene area was successfully disclosed in the current investigation using the ISH method with a digoxigenin-labeled probe.</p> 2024-02-23T00:00:00+08:00 Copyright (c) 2024 Nihat Toplu, Tuba Çiğdem Oğuzoğlu, Ayşe Nur Akkoç
