What is Adenosine Triphosphate Testing (AFP Testing)?
Adenosine Triphosphate Testing (AFP Testing) Definition
ATP Testing refers to Adenosine Triphosphate Testing. This rapid and straightforward technique assesses the degree of biological contamination on surfaces, equipment, or water. ATP is a chemical present in all living cells; thus, its detection indicates the presence of living creatures, such as bacteria, mold, or food residues.
A specialized swab is used to collect a sample from a surface to perform ATP testing. The swab is then inserted into a portable instrument called a luminometer, which measures the light emitted from a chemical reaction involving ATP. Higher levels of light indicate higher levels of contamination.
Widely applied in hospitals, food processing facilities, laboratories, and other hygiene-critical environments, ATP testing does not identify the specific type of contamination. However, it quickly signals whether a surface has been effectively sanitized.
As a method for evaluating cleanliness, ATP testing offers a fast and reliable way to detect residual biological material that should have been removed through proper cleaning procedures.
