Effectiveness of Tests to Detect the Presence of SARS-CoV-2 Virus, and Antibodies to SARS-CoV-2, to Inform COVID-19 Diagnosis: A Rapid Systematic Review
Category: Article Summary
Topic: Testing and Treatment
Keywords (Tags): testing
- A rapid systematic review of both SARS-CoV-2 virus and antibody testing found a sensitivity of 87.8% for an initial RT-PCR test, while sensitivity of antibody tests ranged from 18.4% to 96.1% and specificity ranged from 88.9% to 100%. The authors note that estimates of diagnostic accuracy should be interpreted cautiously due to the lack of a clear reference standard to diagnose or rule out SARS-CoV-2 infection. Additionally, the authors found high or unclear risks of bias in the majority of studies, due to unclear methods of patient selection and testing or use of a reference standard that may not definitively diagnose COVID−19.
