All synonyms of the above-mentioned keywords were also included in the search formula for more comprehensive literature. Study screening and selection The retrieved publications were independently selected by four researchers. MetaDiSc 1.4. The Stata 15.0 software was used to draw Deeks funnel plots to evaluate publication bias. Results We performed a pooled analysis of 38 self-employed studies demonstrated in 30 publications. The reference standard was reverse transcription-quantitative PCR. The results indicated the level of sensitivity of CRISPR-based methods for analysis was 0.94 (95% CI 0.93C0.95), the specificity was 0.98 (95% CI 0.97C0.99), the PLR was 34.03 (95% CI 20.81C55.66), the NLR was 0.08 (95% CI 0.06C0.10), and the DOR was 575.74 (95% CI 382.36C866.95). The area under the curve was 0.9894. Summary Studies Kv3 modulator 3 indicate that a diagnostic method based on CRISPR offers high level of sensitivity and specificity. Therefore, this would be a potential diagnostic tool to improve the accuracy of SARS-CoV-2 detection. strong class=”kwd-title” Keywords: CRISPR-based assays, detection, SARS-CoV-2, level of sensitivity, specificity INTRODUCTION Severe acute respiratory syndrome coronavirus Kv3 modulator 3 2 (SARS-CoV-2) was identified as the pathogen of the coronavirus disease 2019 (COVID-19), and it has caused more than 1.45 million deaths worldwide by November 30, 2020.1 Individuals infected with SARS-CoV-2 may exhibit symptoms such as shortness of dyspnea, high fever, and pneumonia, which are fatal for vulnerable individuals.2 Coronavirus-infected inpatients are more likely to develop acute respiratory failure, pulmonary embolism, or septic shock, resulting in death.3 Moreover, with the sharply increasing quantity of infected people and limited assays currently, the development of efficient, rapid, accurate, and sensitive SARS-CoV-2 sensing tools is urgent for general public health in the world.4 Molecular checks and serological checks have been implemented for COVID-19 diagnosis to detect viral RNA and anti-SARS-CoV-2 immunoglobulins, respectively.5 For molecular diagnostic checks, the collection of upper nasopharyngeal swabs is recommended Kv3 modulator 3 by the US Centers for Disease Control and Prevention. So far, reverse transcription-quantitative PCR (RT-qPCR) offers widely been used as the research standard for the detection of viral RNA in SARS-CoV-2.6,7,8,9 However, it requires well-trained personnel and advanced equipment, which limits the application of RT-qPCR, especially in resource-constrained developing countries.10,11,12 Metagenomic next-generation sequencing is another molecular test to identify SARS-CoV-2, but the sensitivity of this method is restricted from the influence of the human being sponsor background.13 On the other hand, the serology checks, including immunochromatographic analysis and enzyme-linked immunosorbent assay (ELISA), are not sufficiently accurate in detecting SARS-CoV-2.4 In addition, asymptomatic patients are considered to play a major part in the spread of the virus.14 These factors increase the need for effective, cheap, and rapid alternative methods.4 The clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated proteins (Cas) system shows strong collateral activity against single-stranded RNA and DNA targets through molecular immune mechanisms, providing accurate ways of nucleic acid detection highly.15 The mechanism from the detection system may be the specific binding and cleavage activity of CRISPR-Cas. After the primers for invert transcription loop-mediated isothermal amplification Kv3 modulator 3 or invert transcription recombinase polymerase amplification understand the specific parts of the SARS-CoV-2 genome, the targeted nucleic acidity is certainly amplified at a continuing temperature. The information RNAs focus on SARS-CoV-2 E, N, or Orf1ab amplicons using the base-pairing design at attomolar awareness, making sure the amplified nucleotide cleaved with the Cas nuclease accurately. The mark nucleotide is identified in the recognition platform with fluorescence tracking finally.16,17 Therefore, CRISPR is a far more suitable and efficient point-of-care diagnostic technique than RT-qPCR, considering its sequence-specific recognition Hbg1 technique and isothermal amplification techniques.18,19,20 Within this scholarly research, we conducted a systematic meta-analysis and review to measure the diagnostic Kv3 modulator 3 accuracy of CRISPR in detecting SARS-CoV-2 infections, measure the quality of obtainable proof, and perform an in-depth evaluation about the related analysis. Strategies and Components Search technique and supply This research was conducted based on the PRISMA suggestions.21 We decided on four directories, including PubMed, Embase, Cochrane Collection, and Web of Research, and sought out data using CRISPR and SARS-CoV-2 as keywords. Before August 2021 Every one of the technological documents had been released, without vocabulary restriction. All synonyms from the above-mentioned keywords were contained in the search formula to get more extensive literature also. Research verification and selection The retrieved publications were decided on by 4 analysts independently. Predicated on the predetermined exclusion and addition requirements, data had been extracted by examining the game titles, abstracts, and full text messages from the scholarly research. All disagreements were resolved through appointment and dialogue. Addition and exclusion requirements The magazines that met every one of the pursuing criteria had been included predicated on preset circumstances: 1) the researchers experimental goals included the function of CRISPR in the medical diagnosis of COVID-19 infections; 2) the analysis type was a diagnostic precision test, as well as the diagnostic precision was evaluated by looking at the index to.
