WHO recommends specimens from upper respiratory tract like nasopharyngeal (NP), oropharyngeal (OP) swab or wash in ambulatory patients, and lower respiratory specimens like sputum, endotracheal aspirate or bronchoalveolar lavage in patients with more severe respiratory disease for the quantitative assessment of SARS-CoV-2 RNA level through real-time reverse transcription polymerase chain reaction (rRT-PCR). 17 Azzi et al collected saliva from 25 COVID-19 patients (confirmed by NP swabs) through the drooling technique and all were tested positive for the presence of SARS-CoV-2, while there was an inverse association between lactate dehydrogenase (LDH) and Cycle threshold (Ct) values (considered as semiquantitative indicators of viral load). Saliva is more sensitive for SARS-CoV-2 detection in COVID-19 patients than nasopharyngeal swabs.	./cache/cord-255498-npk4zv4i.txt	./txt/cord-255498-npk4zv4i.txt
