Systematic review with meta-analysis of the accuracy of diagnostic tests for COVID-19
To collate the evidence on the accuracy parameters of all available diagnostic methods for detecting SARS-CoV-2. A systematic review with meta-analysis was performed. Studies reporting data on sensitivity or specificity of diagnostic. Computed tomography has high sensitivity (91.9%) but low specificity (25.1%) For RT-PCR tests, rectal stools/swabs, urine, and plasma were less. RT-PCR remains the gold standard for the diagnosis of COVID-19 in sputum samples.
