What is ATP Testing and why is it worth doing? 21/01/2021Adenosine Triphosphate (ATP) testing is what we use to determine how clean a surface really is and gives us a good starting point to review our cleaning processes and the effectiveness of cleaning already in place.
But how does it work?
ATP is an energy molecule found in all living things from bacteria all the way up to humans. The detection of ATP is therefore a clear indicator in determining whether the cleaning process has been able to remove a large amount of detectable ATP. ATP testing works by swabbing a surface and then combining that swab with a liquid-stable reagent. Once these two are mixed together it causes a chemical reaction that emits small amounts of light. The mixture is then placed inside the handheld device which detects the light levels and give a true scientific reading of how much ATP has been detected. The lower the number the better. Anything below 100 is considered good and anything scoring below 10 would pass an NHS clinical test.
Benefits of ATP Testing
- Its a quick and easy way of validating cleaning processes and practices
- Reducing chances of safety breaches especially when food safety is concerned.
- Readings can demonstrate cleaning effectiveness to all types of customers
- The tests can be used to educate staff on the importance of cleaning in the workplace
