Reagents and other working solutions
WARNING
Incorrect results due to incorrect reagent volume
r Application faults may cause an undetectable loss of reagent.
o Always store reagents according to specified storage conditions.
o Reagents, once used, should not be used on other COBAS
®
AmpliPrep Instruments
which are not connected to the same AMPLILINK system (a system is an
AMPLILINK client-server installation and all connected instruments and analyzers).
WARNING
Incorrect results due to expired reagents or mixing kits
r Data obtained using expired reagents are not reliable. Reagents are supplied in a kit
package. Mixing reagents from different kits may also lead to incorrect results.
o Do not use reagents that have exceeded their expiration dates. Replace expired
reagent with unexpired reagents before sample processing.
o Do not mix kits. Reagent cassettes from the same kit package must all be loaded
together.
WARNING
Incorrect results due to reagent cassette interchange
r Reagent cassettes for the COBAS
®
AmpliPrep Instrument connected to the same
AMPLILINK system can be interchanged (a system is an AMPLILINK client-server
installation and all connected instruments and analyzers). But using a
COBAS
®
AmpliPrep Instrument cassette already used on a COBAS
®
AmpliPrep
Instrument that is connected to a different AMPLILINK system may lead to incorrect
results.
Samples and sample racks
WARNING
Incorrect results due to sample mismatch
r Manual mismatch of samples or sample IDs may lead to incorrect results. Whenever
possible use a barcode scanner or an LIS for input of sample IDs to minimize manual
input. Cross-check each manual input of sample IDs to minimize manual sample
mismatch.
WARNING
Incorrect results due to sample rack interchange
r Using a sample rack from a different AMPLILINK system may lead to incorrect results
(a system is an AMPLILINK client-server installation and all connected instruments and
analyzers).
Do not interchange sample racks among different AMPLILINK systems. Each sample
rack may be used on one individual AMPLILINK system only. Each sample rack has its
own individual rack ID, which the instrument or analyzer uses for identification
purposes.
If more than one AMPLILINK system is used in the same lab, be sure to dedicate each
sample rack to one single, individual AMPLILINK system (e.g. by using individual
sample rack ID ranges for each AMPLILINK system).
Cross contamination of samples
WARNING
Incorrect results due to carryover
r Traces of analytes or reagents may be carried over from one test to the next. Take
adequate measures to safeguard additional testing and to avoid potentially false
results.
