Become Covid 19 Secure

We Can Fight the Virus If We Stick Together and become
Covid-19 Secure

The latest service offers the availability to test surfaces for Coronavirus (COVID-19) and also Protection Products to help prevent your customers and staff being exposed to Bacteria and Viruses such as Coronavirus (COVID-19)

Our unique test will not just indicate the presence of COVID-19 but also the amount collected, giving indication of how heavily infected a surface is and the likelihood of fomite transmission. For clarity this test does not test for the covid 19 strain itself but tests for the Coronavirus that creates the disease.

This service will assist in the long term fight to keep our population safe from Coronavirus (COVID-19). can provide 1-2 day results on the virus’s presence/ quantity on any surface. Our partners new testing capabilities allow workplaces / public places to test for suspected Coronavirus contamination and isolation hospital wards and their equipment checked to ensure their cleaning processes are providing sufficient disinfection.

The website is run and operated by Dunston Business Village Ltd the leading managed office space provider in South Staffordshire.

Dunston Business Vilage Ltd has been awarded the UK distributorship rights for the testing of covid 19 surface testing and auxiliary services from Anderson Caledonia.

Who combine expertise and capital equipment to meet Sterilisation and Environmental Testing needs. Specialising in Global Regulatory Compliance and Customised Solutions to provide Rapid Responses to their customers

Dunston Business Village in joint collaboration with Anderson Caledonia built one of the first laboratories in Europe providing an environmental surface Coronavirus (COVID-19) identification service

COVID 19 Test Process is partnering with one of the first laboratories in Europe providing an environmental surface Coronavirus (COVID-19) identification service. Our partner laboratory is located in Staffordshire and consists of a purpose built virology test suite and a separate UKAS accredited water/environmental sample test laboratory.

The test looks for the RNA of Coronavirus (COVID-19) in very small quantities left on surfaces as a result of fomite transmission. It is not known the volume of COVID-19 required to cause an infection or the number of infections caused by touching surfaces that have residual Coronavirus (COVID-19) left on them. Recent studies have shown that COVID-19 can survive up to 9 days on surfaces such as plastic, metal and glass and up to 5 days on wooden surfaces. The virus’s viability on these surfaces poses a significant threat via fomite transmission.

By testing surfaces in areas where high risk patients stay and / or where there are high volumes of human interactions facility managers are able to better coordinate their cleaning regimes to reduce the levels of COVID-19 on surfaces or to verify that existing cleaning regimes have been successful

After swabbing the swab will be placed within a viral transport media and stored at 2-8°C. That of a typical refrigerator. This prevents the breakdown of the Coronavirus (COVID-19) post testing. For shipping the sample vial is placed in the cool box supplied with the ice pack which has been stored in a freezer. The cool box will be collected by a courier to arrive at the laboratory the next day.

At our partners UKAS accredited laboratory the samples will be tested utilising a qPCR system, which is one of the two accepted systems by World Health Organisation (WHO) for Coronavirus (COVID-19). Note that due to the recent introduction of the Coronavirus (COVID-19) test it is currently not part of our UKAS scope of accreditation. However, the test and equipment has been accepted by the MHRA as a suitable PCR test and is widely used by the NHS to test human samples.

The qPCR process looks for Coronavirus (COVID-19) RNA in the sample media. It is highly accurate test in which it specifically detects strands of Coronavirus (COVID-19). The test will return a level of Coronavirus (COVID-19) found on the swab accurate to less than 100 strands of RNA due to dilution of the sample during testing. To gain a further insight into the level of surface contamination, the test also gives a result of how much Coronavirus (COVID-19) is present.

We look to report the results within 2 days of the test samples arriving at our laboratory. The test results will be sent by email or by our online database system once a customer account is set up. The test results will indicate the presence or absence of Coronavirus (COVID-19) in the areas tested by the customer.

(All of the components required for this test have been sourced in the UK and we would like to issue our thanks to the companies who have made the consumables available so we can offer this test)

qPCR is an accurate and rapid way to identify target DNA/RNA. It utilises detection kits, which have can detect less than 100 copies of a target template. PCR or polymerase chain reaction is a method widely adopted in molecular biology to amplify specific segments of DNA/RNA. The amplicon is copied exponentially to generate thousands or millions of copies of target DNA/RNA. In real-time PCR (qPCR), the accumulation of the amplified product is measured as the reaction progresses using fluorescence, in real time, with product quantification after each cycle. It is therefore an excellent modern day tool used for the rapid identification of named organisms including dangerous human pathogens.

Coronavirus (COVID-19) is an infectious disease caused by the evolution of Severe Acute Respiratory Syndrome Coronavirus or SARS. Coronaviruses are a large family of viruses causing flu like illnesses, which range widely in severity. On December 31 of last year, Chinese authorities alerted the World Health Organization of an outbreak of a novel strain of coronavirus causing severe illness. The virus has spread across the globe causing panic and has since been classed as a pandemic.

A: The Centre for Disease Control (CDC) in the USA details that while direct contact via respiratory droplets is believed to be the main cause of transmission there is a possibility for transmission via aerosols and surfaces. The CDC recommends that any surface that has been within 2 metres of an infected person should be disinfected if it is to be used within the next 7 days.

A recent article from South Korea examining an outbreak at a call centre showed that sustained proximity with a carrier was required in most cases to create an infection but not always. Whether this was via the air or surfaces or both was not identified. The study was also interesting in showing that the number of asymptomatic carriers in the outbreak was only 5% and that none of the asymptomatic carriers infected anyone in their household.

An article from Malaysia emphasised how quickly the virus can spread over a few days of close proximity. In 3 days; up to 500 people during a gathering at a mosque, caught the virus from only a few initial carriers. The gathering included holding hands, standing shoulder to shoulder and sharing food.

A: A recent study at a Wuhan hospital handling COVID patients looked at different items for coronavirus. The most contaminated items were computer mice, followed by the floor, trash cans and patient bed hand rails. The study did not indicate the level of coronavirus found but only its presence and was also only undertaken in wards and the ICU of a hospital and not in a wider area. The level of positive samples results was as high as 75% for computer mice in the ICU. Another study of patient rooms in Singapore also found coronavirus in the environment with 61% samples positive in a room prior to cleaning. The positive samples included door handles, patient bed rails, toilet bowl and floor. There were no positive samples in the corridor outside or the ante room. Two other rooms which had been cleaned prior to testing produced no positive samples.

The high level of contamination of the computer mice suggests that the virus is transmitted by the hands as well as through the air. The studies also show that properly cleaned surfaces will be clear of the virus.

A: There have been at least 4 studies which have looked at the time coronavirus can last on different type of surfaces. These studies have shown that the type of surface and the environmental conditions are important in determining the time that the virus remains on a surface. Note that the virus cannot replicate outside a host (the human body) and so will only decay in the environment.

Overall, the studies have shown that on hard surfaces such as steel, plastic or glass at 20°C room temperature the virus will remain in a collectable form for about 4 to 5 days. This time will be shorter for fabrics and paper. A rise in temperature will accelerate the decay but at 4°C which is equivalent to a fridge the virus may last for a month.

The data supports the CDC advice that a surface should be safe after 7 days.

A: There is no clear data on the level of coronavirus required to start an infection which is known as the minimum infectious dose. The high rate of transmission of COVID suggests that it is fairly low. Studies on flu which is also highly infectious have shown that around 1,000 copies are required to create an infection.

A recent German study has found that a patient swab at the start of a COVID infection has over 600,000 copies / strands of RNA per swab.

There is no safe level of viral load on a surface but any test method would ideally show that a surface swabbed has less than 100 copies of coronavirus.



A: Surface testing can be used for a number of reasons;

  1. To verify that a contaminated area is now safe to use
  2. To check that cleaning policies are effectively being implemented
  3. To get an understanding of the level of risk for a location with high traffic passing through such as an airport, supermarket or train station.
  4. As an indication of community based-infection rates by continually checking a set high profile traffic location. This can be seen as alternative to sewage testing.

A: When testing a human, you expect to collect a dose in excess of 100,000 copies from a positive result. When testing a surface, the level of virus collected is likely to be much smaller (down to 100 copies) and the absolute level collected is important. To ensure all the viral particles collected are maintained until tested, the swab is placed inside viral transport media straight after testing, which is then kept cool to avoid RNA disintegration. At the time of testing the precise results from the qPCR process are recorded and the viral copy number calculated.


A: The highest risk surfaces are those that have been directly exposed to a COVID carrier’s coughs or hands. Hard surfaces retain the virus for longer than fabrics or paper. Potential areas to swab include computer mice, touch screens, door handles, sinks and floors. A single swab can be used to swab multiple surfaces for an initial screen.

Any surface that has residual cleaning chemicals or is wet might destroy the virus producing a negative result which is not representative of the level of coronavirus in the environment tested.




A: A study in Singapore of 3 patient hospital rooms with COVID showed that the rooms that had been cleaned were free of the virus but the one that was not had high contamination. This study suggests that standard cleaning with disinfectant is very effective against the virus. However, for rooms with very high contamination a more comprehensive decontamination using vaporised hydrogen peroxide may be required.

It is important that if there are positive samples the cleaning team is supplied with appropriate training and personal protection equipment (PPE). The major risk once a virus has settled is contact especially with hands and not aerosolization of the virus. Please see the CDC sheet for more information on handling a contaminated area.
