What is the SARS-COV-2 Surface Checker?
How to perform a test
step 1 - add buffer
step 2 - insert the swab
step 3 - wring the swab
step 4 - swab the test surface
step 5 - return the swab
step 6 - wring the swab
step 7 - insert the test strip
step 8 - wait 15 minutes
step 9 - check results
How does it work?
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.

Important Information
- 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 do i use it?
- 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.

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.
