ABSTRACT
A selfcollected gargle sample, which avoids discomfort and largely reduces the dependency on medical resources, is emerging for detection of SARSCoV2. However, the incomplete usage of starting materials for both routine oropharyngeal swabs (OPS)/nasopharyngeal swabs (NPS) and saline gargle (SG) samples implies sensitivity can be further improved. Presented here is a beadbased strategy for preenrichment of SG samples, and results revealed that it acquired about 20 times the starting materials obtained from OPS samples for downstream detection of SARSCoV2. The sensitivity and specificity of this preenrichment strategy were validated in 100 paired preenriched saline gargle (PenSG) and OPS samples and 89 PenSG samples from healthy volunteers. In addition to detection of SARSCoV2, this preenrichment strategy may also be implemented in more clinical settings to optimize detection of other diseases.
