ATP Bacteria Testing

Even surfaces that look and smell sparkly clean may be contaminated with germs and bacteria.

An ATP bacteria test can help you know for sure if an area is really clean of potentially harmful bacteria or pathogens.

AZ Bio is the only biohazard cleanup company in Arizona that offers ATP bacteria testing to confirm how clean the surfaces are. Our goal is to leave areas we clean with very little or no measurable trace of germs.

How we test for bacteria


Adenosine Triphosphate (ATP) is present in all organic material and is the universal unit of energy used in all living cells.

ATP monitoring is a rapid testing method that quickly assesses the cleanliness of surfaces or liquid samples.

Since germs can be transported within a structure, we swab multiple locations inside a home or business to determine to what level the affected area is cleaned.

It’s the same approach used by scientists to measure germs in labs, hospitals, and restaurants.

Swab readings of 0 – 100 relative light units (RLU) are considered to be relatively clean.

Any surface with a reading of 300 or more poses a danger and should be thoroughly cleaned and disinfected immediately.

We aim for RLU readings of 0 to 30.

What we can do for you

Our ATP bacteria services can help you in two ways:

1.) When you hire us for a cleanup, we can swab the cleaned areas and provide test results to verify cleanliness.

2.) We can test areas of concern to help you assess how clean (or not) the surfaces are.

If you need a clean up that can be verified with an ATP bacteria test, or the test alone, call AZ Bio Director of Operations Joe Trasser at 602-515-2364.
