ATP Tests: Surface, Water, and Residue Testing

Although surfaces may look clean in your food preparation, healthcare, sanitation or other business where biofilms may lurk, there can still be residue remaining that can lead to potentially dangerous cross-contamination.

Fortunately, Hygiena ATP testing allows companies to quickly and easily test for the presence of adenosine triphosphate, the organic compound that provides energy to living cells. Hygiena tests accurately indicate the presence of ATP with high rates of sensitivity so that you can determine whether your cleaning processes are sufficient enough to protect your customers and your brand, or if you need to expand upon your safety protocols.

ATP Surface Tests

SuperSnap™ High Sensitivity ATP Surface Test


If you need the most sensitive surface test available in Hygiena’s all-in-one device portfolio, choose SuperSnap™. This surface test detects extremely low ATP levels—being four times as sensitive as UltraSnap—making it ideal as an allergen cross-contamination prevention tool as well as the test of choice when needing to use harsh samples. Plus, it works with the entire spectrum of Hygiena™ luminometers with consistently true results.

Additional benefits include this test’s superior resistance to sanitizer effects and the ability of its pre-wetted swabs when it comes to breaking through biofilm. Prevention programs benefit significantly from this test because it allows companies to identify issues and risks in real-time and then implement corrective actions. Plus, because it’s crafted from 100% recyclable plastics, the carbon footprint is low.

UltraSnap™ ATP Surface Test Swabs


If you’re looking for an all-in-one, user-friendly, affordable ATP surface test with a high degree of sensitivity (0.1-1 femtomoles of ATP), UltraSnap™ can be the right choice. This test provides reliable results in just 15 seconds and it costs up to 50% less than other options. Collect samples with a pen-sized, easy to manage, environmentally friendly device with pre-moistened swabs that’s then used with Hygiena luminometers.

UltraSnap is exceptionally accurate, able to provide more reproducible results because of its unique liquid-stable reagent that comes with a longer-lasting signal strength. These surface tests use between 20 to 80% less plastic than other devices, carefully designed with a low impact on the environment in mind. You can use it to test wet or dry services, confident in its ability to handle temperature abuse.

ATP Water Test

AquaSnap™ ATP Water Test


AquaSnap™ measures free ATP in solution, as well as microbial ATP, providing consistent real-time results. Here’s how it works. This easy to use, economical device contains detergent that releases the ATP that’s connected to organic matter and inside microbes. Then, the difference between total and free ATP is detected and that difference illuminates the amount of the sample’s microbial contamination.

This ATP water test is ready to use, just out of the box, and contains a dipper that’s specifically designed to collect 100 µl of water. Why is that last part important? Because that’s what ensures the sample collection is consistent and reduces user variation so that you can count on accurate, repeatable results, even at low RLU levels.

ATP Surface & Water Test FAQs

When should ATP testing be conducted?
Ideally, you should conduct your ATP testing after you’ve cleaned surfaces but before you’ve sanitized them. Here’s why. Sanitization products don’t work as well when residue still exists on the surface, so it’s recommended that you clean and test for ATP to ensure a clean surface before you sanitize.

Sometimes, of course, you can’t test right after cleaning. In those cases, it’s fine to sanitize and then test. The majority of sanitizers do not have an impact on the reliability of Hygiena ATP testing devices. It’s still important to use the proper concentration and to wait the appropriate dwell time; if that’s followed, then sanitizers should not interfere with the processes or affect the results.

What is an ATP monitoring system?
This is another name for a testing system that allows companies to detect the presence of ATP on surfaces after cleaning.
How do you read ATP results?
ATP is measured in a metric called an RLU—which stands for “relative light units.” If a check-mark appears, this is a pass score, indicating that the surface was thoroughly cleaned. An exclamation point, meanwhile, is a caution result, showing that more cleaning should be considered. An X indicates a fail score. If you get that result, reclean and retest that surface until a caution—or, better yet, a pass score—is achieved.
