Effectiveness of Sample Pooling Strategies for SARS-CoV-2 Mass Screening by RT-PCR: A Scoping Review

Abstract: The ongoing COVID-19 pandemic has hugely impacted the economy of many countries, and there is an acute shortage of diagnostic resources. With the exponential increase in the number of cases and necessity to screen large number of people, there is a steep increase in the demand for diagnostic kits. Pooled-sample testing is a promising strategy to screen a large population rapidly with limited resources. The aim of this work was to compile a cohesive literature review of the effectiveness and accuracy of pooled-… Show more

“…Based on the data from previous days or weeks, the software could suggest the pooling tool that would be optimal, including savings, pre-processing time and effort, or other metrics that could assist. This might provide the optimisation that would be capable to provide the best achievable savings, which are direly needed in low resource settings [ 30 ].…”

“…However, inaccurate results have been identified in more than one area within the process, particularly the high risk of false-negative results for borderline positive patients with a high Ct value (low viral load) due to viral dilution [ 24 ]. Nevertheless, this technical limitation could be overcome by using highly sensitive kits with additional thermal cycles to reduce the possibility of missing “weak positive” COVID-19 test results [ 24 , 25 ].…”

“…The other benefit of pooling samples is to allow better at-home quarantine decisions amongst communities. For instance, pooled samples from the whole family of a suspected case can provide guidance on strict quarantine for the entire family, to reduce disease transmission in the community [ 23 ].…”
