Protect business continuity and identify the presence of asymptomatic staff using our COVID-19 staff screening surveillance service.

Routine COVID-19 surveillance testing gives you early warning of infection, allowing targeted measures to be taken to stop the spread.


COVID-19 surveillance looks for the presence of infection in groups to inform health management decisions at the population level. Ongoing surveillance is especially effective with groups in repeated contact, such as classroom cohorts or work teams.


Our Surveillance solution uses gold standard RT-qPCR technology which is the most sensitive COVID detection method according to the CDC.


Unlike nasopharyngeal swabs, saliva collection is minimally invasive, making it ideal for routine testing. Saliva eliminates the need for specialised training and collection materials that are in short supply.

Each saliva specimen kit contains a collection aid, cryovial transport container and instructions, which make it simple and easy to use, resulting in a comfortable, no mess collection process. 

Batches of saliva specimens are returned to our laboratory, at which point they are pooled in batches of up to 5 and submitted for testing using Polymerase Chain Reaction (PCR) techniques recommended by Public Health England (PHE).


Our CE approved saliva collection kits include all the neccessary materials to safely collection and transport COVID-19 surveillance samples from your workforce. Each kit contains the sampling materials to carryout surveillance testing of up to 5 staff members / week and the subsequent batch PCR laboratory testing.



We aim to process surveillance saliva samples and issue results the same day received at our laboratory. 



You should firstly identify groups within your workforce depending on the level of their interactions with one another. Saliva samples are pooled in groups of up to 5 and should follow the group format that already exists in current business operations so actionable results can be taken without affecting other teams in the case of a positive result. 

Frequency of testing is critical for transmission reduction, we recommend surveillance testing is carried on the workforce at least once or twice a week. To learn more about designing a COVID-19 surveillance testing program click here


Each kit is priced at £180+VAT (£36/employee) which includes 5x saliva collection aids / transport containers, return packaging (ice packs, thermosafe box) and the pre-paid pooled PCR sample anlaysis. A postage and packaging fee of £3.95 is charged on all orders.

Diagnostic testing looks for occurrence of COVID-19 at the individual level when there is a reason to believe an individual may be infected. Surveillance testing looks for infection within a population or community, and can be used for making health management decisions at the population level.

For example, if routine COVID-19 surveillance reveals the presence of infection in a workplace population, management might perform diagnostic testing to determine who is infected, and could even elect to close a facility pending diagnostic test results to prevent further spread.

Most customers test twice a week. Testing at least 2 times per week allows you to detect COVID-19 in its earliest stages of infection with minimal cost and disruption to your school or workplace. As test results are representative of only the specific time of test, testing frequency is an important consideration for detecting infection. A sporadic testing regimen could lead to undetected infections in a population. Even testing once a week allows you to detect and slow the spread of COVID compared to no testing effort at all.

No. Our COVID-19 Surveillance Test Kit is marketed for surveillance and research use only. It is not for use in diagnostic procedures. Individual results may not be returned to the tested population. To prevent obtaining individual results in the first place, it is recommended to pool samples. Sample pooling also increases the capacity and speed of testing efforts and reduces costs.

RT-qPCR, or reverse-transcription quantitative polymerase chain reaction, provides accurate, quantitative results within hours. It is the current gold standard method to test for SARS-CoV-2 infection due to it’s high sensitivity. RT-qPCR can detect a miniscule amount of RNA, specific to the pathogen, and make exponential copies of it until there are over one billion copies of that particular RNA segment. This is why RT-qPCR is able to detect an infection at earlier stages, even when viral loads are low. Our COVID Surveillance solution can detect an infection with as little as 5.8 viral copies per microliter of saliva.

Rapid antigen tests can provide results faster than RT-qPCR but at the expense of accuracy and sensitivity. Rapid antigen tests detect proteins on the surface of the virus, yielding qualitative results that heavily depend on higher viral loads for detection. Compared to RT-qPCR, antigen tests need a sample to contain thousands, or even tens of thousands, of viral particles per microliter to produce a positive result.

In cases where the sample has low amounts of virus, rapid antigen tests may be unable to detect a COVID infection and give a false-negative result. Multiple studies, including guidance by the CDC, concur that the sensitivity of rapid antigen tests are significantly lower than RT-qPCR8. One study found that rapid antigen tests detected between 11.1% – 45.7% of RT-qPCR-positive samples from COVID-19 patients. Due to the lower sensitivity of antigen tests, the FDA10 and CDC11 recommend confirming negative results with a RT-qPCR test.

Due to the minimally invasive and painless nature of saliva collection, saliva is more conducive for routine surveillance testing. Saliva is self-collected and eliminates the need to train specialized healthcare personnel on the collection process, making it easy to collect saliva on a regular basis. Studies have also found that saliva is as sensitive, if not more sensitive, than nasopharyngeal swabs in detecting COVID-19. In addition, the complicated sampling procedure of nasopharyngeal swabbing increases the risk of variable and unreliable results.

If infection is detected within a pooled group we advise that the following actions are taken:

1) Refer people for diagnostic testing
2) Discontinue group interactions
3) Decontaminate hotspots and surfaces within the building
