- A prospective study of pooled saliva specimens for RT-PCR testing for SARS-CoV-2 yielded lower sensitivity compared to nasopharyngeal (NP) or mid-turbinate (MT) swabs, but adequate detection in samples with high viral loads. Saliva specimens had 81.8% positive agreement with NP swabs, which rose to 90.0% positive agreement among samples with moderate to high viral load (Ct ≤34) in an analysis comparing 459 paired NP and MT swabs from 449 symptomatic individuals.
