The following article explains; How Does A.T.P testing work.
ATP (Adenosine Triphosphate) testing is a method used to determine the presence of biological contamination, such as bacteria, yeast, or mold, in a sample. The test works by measuring the amount of ATP (a molecule found in all living cells) in a sample using a luminometer.

Typically, the sample is mixed with a reagent called luciferin, which reacts with ATP to produce light. The amount of light produced is proportional to the amount of ATP present in the sample. The light emission is then measured by the luminometer, and the result is reported in relative light units (RLU). High RLU values indicate high levels of ATP and therefore high levels of biological contamination.
ATP testing is widely used in a variety of industries, including food safety, environmental monitoring, and healthcare, as a quick and simple way to assess the level of hygiene and cleanliness in a given area.
