ATP Testing - what and why | Touch Zone Clean

ATP Testing


How does it work and can it help with the fight against Virus Infection?

ATP testing has been around for over 30 years predominantly in food and beverage sectors and not just a pie in the sky invention due to Covid’s arrival. The use of ATP testing has grown as a result of efforts to ensure high levels of sanitisation, however, it is important that anyone considering introducing ATP testing understands what it measures and limitations of the system


Fact – ATP systems do not detect viruses directly.

Viruses cannot generate or store energy in the form of adenosine triphosphate (ATP) therefore ATP systems do not detect viruses directly. Performing ATP CleaningVerification does not guarantee removal of viruses on surfaces.

To repeat, ATP does not eliminate nor show if a virus is present or not. This is a common misconception made worse by unscrupulous claims and suggestions.


So why use ATP testing

ATP testing is a crucial tool for ensuring that surfaces have been thoroughly cleaned and disinfected. By taking this corrective action and ensuring cleaning has been performed to the highest standard, especially at this time, we are lowering the risks significantly of a virus being present. Therefore protecting staff and members.


What is RLU ?

RLU stands for Relative Light Unit and is the unit of measure used in bioluminescence. When a test swab is activated a bioluminescent reaction occurs generating light output. Luminometers measure and quantify that light with an RLU output. The questions always asked are –  Where do you set this? What should it be? Unfortunately, there are no legal standards set. This is of course, although frustrating, is for a very good reason. Imagine having a set RLU over so many different industry sectors. This would never work. A hospital involving sterile services compared to an airline for example will have very different challenges and will obviously work to very different RLU limits. Testing and validating is key to helping you to set your own benchmarks.


How does ATP testing help with the application of Antimicrobial Surface Protection?

For antimicrobial surface protection to work to its optimum performance it is vital that surfaces are cleaned and sanitised thoroughly. This is particularly important before the initial application. To help let’s draw comparisons to painting a surface. Before applying the paint you would ensure that the surface is free from grease and debris so that the paint forms a smooth layer and a great finish. Antimicrobial surface solution ‘coats ‘ the surface in a similar way to paint. The best way to ensure a thorough coating is to ensure that the surface is clean prior to application.
