Diagnostic Accuracy of Antibody-based Rapid Diagnostic Test in Detecting Coronavirus Disease 2019: Systematic Review
Archives of Medical Science
IntroductionThe rapid transmission of Coronavirus disease 2019 (COVID-19) requires a fast, accurate, and affordable detection method. Despite doubts of its diagnostic accuracy, Rapid Diagnostic Test (RDT) is world-widely used in consideration for its practicality. This systematic review aims to determine the diagnostic accuracy of antibody-based RDT in detecting COVID-19.Material and methodsA literature search was carried out on five journal databases using the PRISMA-P 2015 method. We included
... method. We included all studies published up to February 2021. The risk of bias was evaluated using The Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Diagnostic Test Accuracy Studies. Data regarding peer-review status, study design, tests kit information, immunoglobulin class, target antigen, and the number of samples were extracted and tabulated. We estimated the pooled sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) with a 95% confidence interval.ResultsThirty-three studies met the eligibility criteria. The pooled data results showed that the combined detection method of IgM or IgG had the highest sensitivity and NPV, which were 73.41% (95% CI: 72.22-74.57) and 75.34% (95% CI: 74.51-76.16), respectively. The single IgG detection method had the highest specificity and PPV of 96.68% (95% CI: 96.25-97.07) and 95.97% (95% CI: 95.47-96.42%), respectively.ConclusionsAntibody-based RDT is not satisfactory as a primary diagnostic test but has utilities as a screening tool.
