NASAL SWAB AS PREFERRED CLINICAL SPECIMEN FOR COVID-19 TESTING IN CHILDREN

Abstract: The first pediatric study demonstrating significantly higherpositivity rate of nasal (mid-turbinate) swab testing over oropharyngealswab testing in detecting SARS-CoV-2 (Fisher exact test 0.046, Cohen K0.43, confidence interval 95%, 0.014–0.855). Benefits might include lowercollection-related hazard for healthcare workers. We recommend it as preferred choice for swab-based SARS-CoV-2 testing in children.

Suboptimal Biological Sampling as a Probable Cause of False-Negative COVID-19 Diagnostic Test Results

False-negative severe acute respiratory syndrome coronavirus 2 test results can negatively impact the clinical and public health response to coronavirus disease 2019 (COVID-19). We used droplet digital polymerase chain reaction (ddPCR) to demonstrate that human DNA levels, a stable molecular marker of sampling quality, were significantly lower in samples from 40 confirmed or suspected COVID-19…
