As part of the ColoSSoS Project (Collaboration on Sewage Surveillance of SARS-CoV-2), Water Research Australia together with the National Measurement Institute, have released the Inter-laboratory Study.

Inter-laboratory studies play an important role in the improvement of the quality of scientific analysis and help ensure comparable results over time and between laboratories. This study has produced data on the performance variations that arose from the different protocols developed for sewage surveillance of SARS-CoV-2 over the last 12 months – allowing laboratories to improve their protocols, and if necessary, improve the accuracy and consistency of their methodology.

Understanding proficiency of different laboratory protocols and the reasons for any differences in performance is imperative to ColoSSoS, specifically with regards to method reproducibility and Limits of Detection in a low COVID-19 case setting, such as that in Australia and New Zealand.

With sewage surveillance of SARS-CoV-2 well-established across multiple jurisdictions and data being used on a daily basis to track and manage potential new outbreaks, it is important that laboratories maintain the quality of their work.

This study has allowed the water industry to understand the acceptable variations in the methods being used across Australia and New Zealand for sewage surveillance of SARS-CoV-2.  Going forward this will give industry the confidence to further develop these methods to address emerging issues as the pandemic continues.
