Fig. 3: Deployment of clinical testing at the UCLA COVID-19 SwabSeq testing laboratory.

a, Since November 2020, we have used SwabSeq for large-scale screening in conjunction with our saliva and nasal swab collection processes. We have scaled up to nearly 10,000 samples per week and are continuing to increase our capacity. Week number refers to the week of the year spanning 2020–2021. Our weekly percentage positivity rate ranges between 0.3% and 2.4% over this period. b, Our clinical deployment streamlined the pre-analytical testing process such that we receive tubes that are ready to be processed through our testing protocol.
