The AMPLILINK Software is setup as a client/server architecture. This allows the use
of several decentralized AMPLILINK control units each controlling individual
instruments and/or analyzers.
The AMPLILINK Software also handles the test definition file (TDF) for each assay it
supports, captures sample identification, absorbance results, and interpretations and
comments from the data output for the instruments it supports and presents the data
in the user interface.

General flag description AMPLILINK Software
Flags Software Version 3.3 and 3.4 Series
General flag description
The AMPLILINK Software and the connected analyzers and instruments generate
flags to indicate particular events during a run. An event that triggers a flag could be
for example a control failure, an aborted run, the occurrence of a hardware error, or
the fact that a diluted sample has been used.
Certain flags generate a flag remark in the Results window. The flag remark indicates
the cause of the flag.
Understanding the flag concept is a prerequisite for effective flag interpretation and
decisions about corrective measures and preventive actions for results with flag
remarks.
Flags
Flags are part of the result details and can have different impacts on results and result
interpretations (e.g. certain flags with a flag remark might set the result to Invalid or
Failed). Not all flags require a user action but each flag that generates a flag remark
must be interpreted. A result can have more than one flag.
There are two major flag categories:
Flags without a flag remark These flags provide additional information. The final result is valid and can be
reported.
Flags with a flag remark These flags can have an impact on the final result and must be interpreted.
A flag is built in the following way:
o The first four positions are reserved for the flag code. It consists of a system code
and two numerical digits.
o To the right of the flag code the flag text is displayed. It informs you about the
cause of the flag (e.g. high drift or high temperature).
o At the end of the flag the channel number is displayed (only used for channel-
specific flags generated by COBAS
®
TaqMan
®
Analyzer and COBAS
®
TaqMan
®
48
Analyzer).

Flag code
The flag code consists of four characters. The first two characters indicate the system
which has generated the flag. The last two characters represent the code number.
Together they build a unique flag identifier.
The display of the flag code can be enabled or disabled in the Configuration window
Processing Configuration dialog box by the administrator. It is recommended to
enable the flag codes.
The following table shows the system codes used in the flag code.
Flag text
The flag text informs about the cause of the flag.
Channel-specific flags
Some flags generated by COBAS
®
TaqMan
®
Analyzer and COBAS
®
TaqMan
®
48
Analyzer are channel specific. The number at the end of the flag (e.g. SPK_DETECT-
2) indicates the channel for which the flag was generated.
Flag remarks
Certain flags generate a flag remark. The flag remark is displayed in the Results
window and indicates the cause of the flag. Only the flag remark of the flag with the
highest priority is displayed in the Results window if a result has more than one flag.
Related flags are grouped to the same flag remark (e.g. flags that are generated during
the pre-check calculation like DRIFT_HIGH-n or BLTOOHIGH-n all generate the
same flag remark PRECHECK).
u
For details about flag priorities and a list of flag remarks, see List of all AMPLILINK
Software flags (p. 16)
q
There are flags that have no flag remarks associated with it. In this case no flag remark is
displayed in the Results window.

Curve display / normalization
Flags can be evaluated in more detail using the growth curve in the Result Detail
dialog box.
Figure 12 Growth curve in Measurement Details tab
As default the growth curves will be displayed normalized. If the result is Invalid, the
growth curves will not be displayed under the normalized display. In order to view
the growth curves the normalization can be disabled.
Figure 13 Growth curves of a valid result
Normalization Normalization is used to compare different growth curves that have different
baselines. Different baseline levels occur due to usage of different fluorescence dyes.
After normalization, the baseline for each growth curve will be adjusted to a common
baseline. Depending on the algorithm used, the baseline is set to 1 or to 0 after
normalization.
The elbow value, also called threshold cycle (Ct) value, will be calculated using the
respective normalized growth curves.

TADM flag remark
Description A TADM flag remark occurs when the predefined pressure bands were exceeded
during pipetting. The TADM flag remark can occur during aspiration as well as
dispensing.
Flags
Cause There are several causes for a TADM flag remark:
o Tube diameter is defined too large. The pipetting channel loses the volume level
during pipetting and air is aspirated.
o Samples with foam. The liquid level is detected at the top of the foam and air is
aspirated during pipetting.
o Sample with unusual physical properties (for example the viscosity of a sample is
too high).
o Leakage of pipetting channels or tips.
Remedy o Ensure that the diameter of primary tubes is defined correctly. In case tubes with
various diameters are used in a run use the smallest diameter for tube definition.
o In case of samples with foam centrifuge the sample or remove the foam manually.
o There are two ways to process samples with unusual physical properties:
1) Centrifuge the sample and process it on the cobas p 630 instrument again.
2) If there is no possibility to centrifuge the sample, pipette the sample manually
and load it on the COBAS
®
AmpliPrep Instrument.
q
Inappropriate storage and treatment of samples affect the physical properties. Pay
attention to store and treat the sample in a correct way.
o Leakage of pipetting channels can be checked by performing daily maintenance.
Liquid flag remark
Description The sample volume is insufficient for the pending pipetting. The cobas p 630
instrument does not move deeper than 6 mm above the bottom of the primary
sample tube to prevent contamination of the pipetting channel and damaging the
instrument.
