Educational institutions, resorts & hotels, childcare, eldercare, and any businesses with employees in groups or shifts benefit from reliable data on SARS-CoV-2 virus prevalence in their workforce, students and residents. Geosyntec provides surveillance data to our clients to understand if small groups such as sports teams, classes, residents, and work teams harbor SARS-CoV-2 and are at risk of further infection.

Group surveillance informs operational decisions on outbreak risk mitigation while balancing business continuity. Our approach employs pooled saliva samples from populations of people who interact with each other in the course of their day. Surveillance monitoring involves the collection of anonymous individual samples of saliva that are pooled and analyzed to provide an indication of the presence or absence of SARS-CoV-2 in the pooled population. A negative result clears the entire population as SARS-CoV-2 free at the time of sampling and allows continuation of normal operations. A positive result indicates that some within that pooled population are shedding the virus and also indicates that the others in that pool are at risk. The facility’s COVID-19 response plan will guide appropriate actions in the event of a positive result.

How We Can Help

  • Planning to help you use pooled saliva surveillance for the best benefit of your operation.
  • Next day results minimize down time and quickly trigger next steps for populations with positive detections.
  • Simple collection protocol that small children and seniors can do themselves without frightening and invasive nasal swabs.
  • Highly sensitive and reliable results provide confidence in decision making.
  • Geosyntec employs the most sensitive method, reverse transcriptase-quantitative polymerase chain reaction(RT-qPCR) analysis for definitively detecting SARS-CoV-2 in pooled saliva samples.
  • Positive and negative controls ensure each analysis is accurate and will yield a positive result if the viral RNA is present.

Pooled Saliva Surveillance analyzes populations for the presence or absence of SARS-CoV-2 virus. In Canada, sample collection must be performed under the supervision of a qualified medical professional. Surveillance results indicating the presence of SARS-CoV-2 in a sample requires subsequent diagnostic testing of individuals by a laboratory licensed to conduct medical tests.
