AccuPoint Advanced HC User’s Guide

INTRODUCTION
Neogen’s AccuPoint Advanced Healthcare (HC) ATP cleaning validation and tracking
system is a lightweight, handheld reader for validating a cleaning program’s
effectiveness. The system detects organic material including bodily fluids, skin cells
and micro-organisms on surfaces and in liquids. The system’s easy-to-use AccuPoint
samplers automatically mix self-contained reagents to quickly generate results.
When used with the AccuPoint Advanced HC Data Manager software, the AccuPoint
reader can record the testing results at specific site locations, along with the date,
time and individual responsible for cleaning. The test site information is entered in the
Data Manager HC program and synced to the AccuPoint Advanced HC reader. The user
simply navigates to the correct site and takes the test.
Up to 5,000 unique testing sites can be tracked with each AccuPoint HC reader. Results
from up to 4,000 tests can be retained at any time and are not lost if the reader loses
power. Four rechargeable nickel metal hydride (NiMH) batteries provide power.
Operating principles and technology
The AccuPoint Advanced HC system utilizes ATP bioluminescence to determine the
cleanliness of test samples. Adenosine triphosphate (ATP) is a molecule found in all
living cells, including bacteria, bodily fluids, skin cells, yeast and mold. Bioluminescence
is a chemical reaction that produces light. ATP bioluminescence occurs when ATP
from a sample comes into contact with luciferase, an enzyme found in fireflies, and
luciferin, a substrate. The amount of light emitted in this reaction is proportional to the
amount of ATP detected in a sample. After a sample is taken the sampler is pressed
into its cartridge, breaking its seal and initiating the mixing of reagents. The reaction
takes place within the cartridge and a detector measures the amount of light produced.
The reading is displayed on the LCD display in relative light units (RLU). According to
preset limits, an icon is displayed indicating a pass, marginal or fail result. These limits
are defined by the operator or by using the system presets.
