Surface Cleanliess Test

Aims

This test aims to evaluate and verify the cleanliness of any surface (e.g. walls & ceilings, kitchen cabinets, air conditioners and dehumidifiers) by finding out how active the microorganisms activities are on the tested area.

How clean is your home?

When mould spores land on a wet or damp surface, they begin to grow. Moulds can cause to health problems because they produce allergens (substances that can cause allergic reactions), irritants, and in some cases, even toxic substances (mycotoxins). Inhaling or touching moulds or mold spores may cause allergic reactions for sensitive people.

Bacteria can enter homes on people, food and pets. Once bacteria are in, they can spread from people to people, or from people to surfaces and back again (cross-contamination). Common bacteria found in home are MRSA (meticillin-resistant Staphylococcus aureus) and E. Coli 0157.

Our test does more than just verify surface and equipment cleanliness. We help you to evaluate the effectiveness of cleaning materials / chemicals and measure the performance of daily cleaning work.

Where should I test?

Samples will be taken from up to 5 items / surfaces, suggested testing locations include…

  • Ceilings & walls
  • Kitchen countertops & cabinets
  • Countertop basins & wash-bowls
  • Toilet bowls & Seats
  • Air-conditioners & dehumidifiers (cooling fins)
Testing device(s)

We adopt Hygiena SystemSURE Plus™ Luminometer to perform the ATP Cleaning Verification. The device gives a numeric measurement of organic material (ATP) on a surface, measured in relative light units (RLU). The more ATP presents on a surface, the higher the RLU measurement. This method is recommended by Centers for Disease Control and Prevention (CDC).

The detection of Adenosine Triphosphate (ATP), the universal unit energy in all living cells, determines if surfaces are truly clean. For those sensitive areas like homes, schools, nurseries and, health institutions (i.e. clinics), ATP Cleaning Verification provides a quick way to detect microorganisms. By collecting samples from the environments, and measure the ATP level, it gives a direct measure of biological concentration in the environments.

RLU levels
  • Hospital: <15
  • Public: <50
