If confirmed in follow-up research and if the diagnostics industry can pivot quickly enough, findings from a South African study could make COVID-19 testing a lot easier for patients and healthcare workers, as the SARS-CoV-2 Omicron variant becomes the dominant source of infection.
In a manuscript posted to the medRxiv preprint server on Friday, researchers from the University of Cape Town reported that saliva samples yielded more accurate results in PCR analyses when Omicron was involved compared with those collected via nasal swabs.
When patients carried the Delta variant, on the other hand, nasal swabs were more accurate, according to the group, led by Diana Hardie, MBChB, MMedPath, who also heads the diagnostic virology laboratory at Groote Schuur Hospital...
