1. Introduction
The luminometer is part of an ATP Hygiene/Sanitation Monitoring
System intended to detect ATP found in organic matter and
microorganisms. The Hygiena luminometer, in conjunction with
Hygiena’s ATP and Micro-snap test devices, measures levels of
contamination on surfaces, water and product samples.
1. Remove swab from test tube and collect sample. Refer
to instructions included with testing device.
2. Place swab back in test tube.
3. Break Snap Valve at top of swab by bending bulb.
Squeeze bulb twice, pushing liquid reagent down swab
shaft.
4. Shake test for 5 seconds.
5. Place test in the luminometer and close lid.
6. Hold the luminometer upright and press “OK”. Reading
will appear in 15 seconds.

1.1 What is ATP?
Adenosine Triphosphate (ATP) is an
organic molecule that is used by living
cells as the main source of energy.
Animal, plant, bacterial, yeast, and mold
cells produce and break down ATP in
order to drive a number of biological
processes. It is the main energy-transfer
molecule in the cell. The presence of ATP on a surface indicates that
the surface has not been adequately cleaned and has the potential
to harbor and support bacterial growth. The residue may also
contain hazardous material including potential allergens. Therefore,
ATP is an ideal indicator of surface cleanliness.
1.2 How Does the Luminometer Work?
The luminometer detects ATP using a chemical reaction.
Luciferin/Luciferase + ATP = Light
A sample is collected using a Hygiena ATP device (see section 1.4).
Surface tests come with a buffer moistened swab bud that aids in
the removal of any biological material (ATP) on either a wet or dry
surface. Once the sample is collected and exposed to the chemistry
(buffer) in the Hygiena device, the ATP contained inside the
collected cells will be released. ATP released from inside these cells,
along with any free ATP picked up from the surface by the swab, is
now available to react with the chemistry in the bulb of the device.
When the Luciferin/Luciferase enzymes are exposed to ATP, light is
produced. The light is detected and measured by the luminometer.
The amount of light detected is directly proportional to the quantity
of ATP collected and accordingly is proportional to the amount of
residue in the tested sample. The higher the reading, the higher the
amount of contamination in the sample.
1.3 What is an RLU?
The luminometer displays results in Relative Light Unit (RLU) values.
The light produced from the Luciferin/Luciferase and ATP reaction in
the swab is emitted in the form of photons. A photon is an
elementary particle and the basic unit of light. The luminometer
detects these photons and displays them directly as RLU values. The
more light detected by the luminometer, the greater the RLU value.
The quantitative RLU reading is then compared against user
programmable thresholds to provide an overall qualitative pass ,
caution or fail result.
The luminometer detects total ATP, not just ATP from bacteria,
yeast, and mold but also the ATP from anything organic in the
sample. Therefore, an RLU value is not the same as a microbial

3
colony forming unit (CFU). Since the luminometer is detecting total
ATP, it is unknown whether the RLU result displayed by the
luminometer is due to the detection of microbial ATP, residual ATP,
or a combination of both. Therefore, a comparison cannot be drawn
between RLU values from ATP and standard plate counts (SPC); or
rather RLU does not equal CFU. True microbial contamination can
only be determined by a standard plate count method that can take
up to 48 hours for results. The luminometer is capable of providing
results in 15 seconds offering a rapid, real-time approach to
hygiene/sanitation monitoring. The luminometer is not meant to
replace microbial testing. It can be an effective tool when
incorporated into a Hazard Analysis Critical Control Point (HACCP),
Good Manufacturing Practices (GMP), or sanitation plan.

The luminometer has the ability to store a list of 5001 unique
Program test points (Prog# 0 to 5000), each with its own upper ()
and lower () pass/fail result threshold values.
Program test point location names can only be programmed into the
luminometer through the SureTrend software. Program pass/fail
thresholds can either be set-up on the luminometer, or set using the
SureTrend software. If a location name is entered and threshold set
in SureTrend, and then downloaded to the luminometer, the
threshold values can’t be changed via the luminometer. This is a
security feature and prevents inadvertent changes to the thresholds
after being set in SureTrend.
TIP: Prog:0 has a special function, whereby the threshold values
defined for Prog:0 are used as the initial values when setting-up
the other Prog thresholds. Setting Prog:0 with your typical
threshold values will save time when setting-up the other Programs.
The luminometer comes with pass/fail thresholds of 10 RLU for pass
and 30 RLU for fail. These pass/fail thresholds were determined
based on a comprehensive study of ATP, food residue, and
microorganism samples. To receive the report or more information
on setting up pass/fail thresholds contact Hygiena or visit our
Question and Answer section at www.hygiena.com.
