Incorrect results or damage to the analyzer due to wrong operation
Operators are required to have a profound knowledge of relevant guidelines and norms as
well as the information and procedures contained in the Operator’s Manual.
o Do not carry out operation and maintenance unless you have been trained by Roche
Diagnostics.
o Carefully follow the procedures specified in the Operator’s Manual for the operation
and maintenance of the system.
o Leave maintenance that is not described in the Operator’s Manual to trained service
representatives.
o Follow standard laboratory practices, especially when working with biohazard material.
Fatigue due to long hours of operation
Looking at the monitor screen over an extended period of time may lead to fatigue of your
eyes or body. Take a rest for 10 to 15 minutes every hour to relax. Avoid spending more
than 6 hours per day looking at the monitor screen.
Incorrect results due to carryover
Traces of analytes or reagents may be carried over one test to the next. Take adequate
measures (e.g. sample aliquoting) to safeguard additional testing and to avoid potentially
false results.
Incorrect results and interruption of analysis due to contaminated samples
Insoluble contaminants in samples may cause clogging or pipetting volume shortage and
deterioration in measurement accuracy. When loading samples on the analyzer, make sure
that samples contain no insoluble contaminants such as fibrin or dust.
Malfunction due to spilled liquid
Any liquid spilled on the analyzer may result in malfunction of the analyzer. If liquid does
spill on the analyzer, wipe it up immediately and apply disinfectant.
