Article Correctness Is Author's Responsibility: Saliva can be more effective than nasopharyngeal swabs for COVID-19 testing

(Elsevier) Saliva samples are easier to collect than nasopharyngeal swabs for COVID-19 testing but can be mixed with mucus or blood, and some studies have found they produce less accurate results. A team of researchers has found that an innovative protocol that processes saliva samples with a bead mill homogenizer before real-time PCR (RT-PCR) testing results in higher sensitivity compared to NPS samples. Their protocol appears in The Journal of Molecular Diagnostics, published by Elsevier.
