ATP Test

What are Relative Light Units (RLU)? 

The principle of the ATP test is based on the firefly luciferase reaction, which can produce light using luciferin and ATP. The amount of light produced is proportional to the amount of ATP in a sample and can be quantified by measuring the light. The results are displayed in relative light units (RLU). RLU are not a standardized unit of measurement like inches or centimeters, and each manufacturer sets their own value for 1 RLU based on their reagent formulations and light detection systems. Therefore, a system that can indicate larger RLU values for a certain amount of ATP is not necessarily more sensitive. Benchmark RLU values are set to determine regular cleanliness in a facility. They are generally set from tens to thousands of RLU depending on sites.

How do I set the standard value for ATP Test?

Standard (benchmark) values are RLU levels that are used to determine the pass-fail criteria for cleanliness levels controls for the test being conducted. Standard values are set using either specific site data or recommendations. Based on the data collected during sampling, Standard Values 1 and 2 are set to develop Action Levels (Figure 1) with tests below Value 1 being a “Pass” test, indicating that cleaning processes are being effective according to the validated methods, above Value 1 but below Value 2 serving as a “Caution” range, indicating that adherence to cleaning processes may be deteriorating and the cause should be investigated, and finally, levels above Value 2 indicate that cleaning has not been effective and recleaning is appropriate.

The ATP Test (Kikkoman A3)

What are the advantages of the ATP Test (Kikkoman A3)?

Since organic debris onsite contains remarkably large amount of ADP and AMP, the A3 Test can detect organic debris more effectively than conventional ATP tests. Accordingly, one can see that the primary consideration for selection of an ATP tests to manage the effectiveness of cleaning is the ability of the test to detect ADP and AMP as well as ATP rather than the precision of the test’s detection of pure ATP.
