Mass Screening Using Saliva Samples and Pooled Testing Strategy For SARS-CoV-2 RT-PCR Detection in Latvia

Non-invasive methods for the detection of SARS-CoV-2

To address the urgency for a simple non-invasive method for the detection of SARS-CoV-2, a study by E. Gulbja Laboratory aims to demonstrate that saliva specimen samples can be used for SARS-CoV-2 detection and screening of extensive population groups via pooling.

“Research findings highlight that saliva specimens are stable for testing for up to 24hrs. The results of saliva samples were consistent with those obtained from NPS from the same patient with 90% sensitivity (95% CI 68.3%-98.7%) and 100% specificity during the first two weeks after the onset of symptoms. Patient-performed simple specimen collection allows testing an extensive number of people rapidly, obtaining results of the spread of SARS-CoV-2, and allowing authorities to take timely measures. Automated sample distribution and collection points are accessible 24/7 enabling a safe, contactless, and efficient way to submit various types of specimen samples for testing.”
