About the sars-cov-2 surface checker (5 tests)
What is the SARS-CoV-2 Surface Checker?
Covid-19 is the disease caused by the SARS-CoV-2 virus. The SARS-CoV-2 Surface checker is a rapid detection kit for coronavirus on surfaces. It is a simple and easy to use 'Do it yourself' swab test kit that produces results within 15 minutes. The checker is for quickly testing your surfaces during the covid-19 crisis. This checker is ideal for high traffic environments that require rapid hygiene testing without the time constraints or difficulty in accessing lab testing.
How to perform a test
Step 1 : Add buffer
Add 15 drops of buffer into the test tube.
Step 2 : Insert the swab
Insert the swab into the buffer and allow it to absorb some of the solution.
Step 3 : Wring the swab
Wring the swab against the edge of the tube to remove excess buffer.
Step 4 : Swab the test surface
In a 'zig zag' motion, swab the surface to be tested.
Step 5 : Return the swab
Return the swab back into the buffer and gently agitate the buffer in the tube by moving the tube slowly left to right.
Step 6 : Wring the Swab
Wring the swab again on the edge of the tube to remove the buffer from the swab.
Step 7 : Insert the test strip
Insert the test strip with the arrows pointing down into the buffer solution and place the cap on the tube.
Step 8 : Wait 15 minutes
Place the tube into the stand so it stays upright and leave for 15 minutes.
Step 9 : Check Results
After 15 minutes, check the test for your results. 2 red lines is a positive test, 1 line is a negative test.

- Positive result allows for immediate action rather than waiting at least a day for lab results
How does the SARS-CoV-2 Surface Checker work?
The checker detects SARS-CoV-2 viral proteins by immuno-detection. This detection method is inexpensive, fast and sufficiently presumptive of viral presence to be of value in hygiene monitoring. Unlike other methods of viral detection such as PCR, immuno-detection requires no specialised equipment or expertise to conduct the test and read results.
The SARS-CoV-2 checker is a lateral flow test (similar to a pregnancy test format). This method involves the interaction of an antibody with a target antigen. In this case, SARS-CoV-2 is the target and the detection kit carries the antibody. The strip antibodies bind to the coronavirus specific Nucleocapsid protein.
A positive test result indicates that SARS-CoV-2 protein N is present at a concentration higher than 3 ng /ml. A positive test result indicates that the hygiene procedures have failed. Action will need to be taken to rectify this. Cleaning and disinfection of the sampled surface is recommended. A re-test will need to be performed to ensure that the viral protein is no longer present.
A more technical explanation of how it works can be found further down the page in the 'In depth technical details' section.
What is in the SARS-CoV-2 Surface Checker kit?
Each kit contains 5 tests.
The kit includes:
- 5 x Detection Strips
- 5 x Swabs
- 5 x Tubes
- 5 x Tube stoppers
- 1 dropper-vial containing 3.5 ml of buffer / reagent
- Instructions for use
Who can use the SARS-CoV-2 Surface Checker?
Anybody can use the checker. No expertise or training is required other than following the instructions included with the product.
Workplaces / companies that may find the SARS-CoV-2 Checker useful:
- Public transport
- Airports and aircraft
- Restaurants / cafes
- Care Homes
- Holiday Lettings
- Service stations
- Gyms / Leisure facilities
- Salons / beauticians
- Tattoo parlours
- Cleaning companies
- Bowling alleys
- Education settings (schools and universities)
This test kit will detect viral proteins. It will not indicate if the virus is inactivated or infectious.
The test is qualitative and cannot predict the quantity of antigens present in the sample.
This test should be considered a hygiene test for verification of decontamination effectiveness or a rapid screening test. NOT for use with samples from human origin or for clinical diagnosis. For environmental testing only.
After opening, the reagents in the kit should be used in 3 weeks.
If strips are stored in a container, the container must be resealed as soon as the necessary number of strips for the operation has been removed, as the strips are sensitive to humidity. Make sure that the provided desiccant bag is present.
How to use the SARS-CoV-2 Surface Checker
- Place 15 drops of included reagent within tube.
- Put swab into the reagent in the tube. Press the swab tip against the tube to remove excess liquid.
- Use the swab to collect sample from surface.
- Shake the swab in the tube to resuspend collected deposits then discard swab.
- Put the strip in the tube
- Positive or negative result will occur within 15 minutes. Wait 15 minutes before reading and recording the result. A light red colour should be considered positive.

Viral detectability : 5 x 103 pfu/mL
Recombinant Nucleocapsid (recNP) protein detectability : 0,3 ng/mL
No cross-reaction with the following viruses:
- Influenza A
- Influenza B
- Respiratory Syncytial Virus (RSV)
- Respiratory Adenovirus
- Coronavirus HKU1
- Coronavirus OC43
- Coronavirus 229E
- Coronavirus NL63
The test is a series of absorbent material compartments that have the capacity to transport fluids spontaneously, by capillarity. Several of those absorbent compartments contain specific reagents, either in a free form in which case they will be carried by the flow of liquid, or immobilised onto the compartment material in which case they stay where they are.
When a test is run, a sample is added to the sample pad. The sample first moves through the conjugate pad, which holds the first anti-virus antibody to which a marker is attached (hence the name conjugate).
The conjugate is carried by the sample flow, attaches to the virus if it is present and continues across to the test and control lines.
When the sample hits the test line, an immobilised second anti-virus antibody catches the virus and the attached conjugate. As more and more viruses are fixed on the test line, the concentration of conjugate increases and a colour develops.
A colour, even a light one, observed at the test line indicates that some virus is present and should be considered a positive.
The conjugate is present in excess proportion to the amount of virus potentially present in the sample, so some conjugate continues to the control line.
Anti-antibody is immobilised on the control line and catches the conjugate antibody. (Anti-antibodies are antibodies from one species e.g. goat, developed against antibodies of another species e.g. rabbit).
As conjugate accumulates on the control line, the line color intensifies. The conjugate line is there to confirm that the test has functioned, even if nothing happens on the test line.
Due to the nature of DIY tests and user variables (that are out of our control), test result accuracy can't be 100% guaranteed. Testing steps must be followed exactly as described in the documentation provided. Must not be used to perform tests on the human body. No part of the test is safe to be inserted into or used on the human body. Tests should used for environmental testing only.

What does a negative result on the SARS-CoV-2 Surface Checker mean?
A negative test result indicates that the virus has not been detected or that the concentration was below the limit of detection (5 x 103 pfu/mL) for the SARS-CoV-2 test kit.
What does a positive result on the SARS-CoV-2 Surface Checker mean?
A positive test result means that the virus has been detected above the limit of detection (5 x 103 pfu/mL) for the SARS-CoV- 2 test kit.
