Overview
General safety information
Test-specific safety information is contained in this manual. For general safety
®
4800
Overview of the test
information (e.g. safety classifications, safety precautions), read the cobas
System System Manual.
The cobas® 4800 CT/NG Test is an in vitro nucleic acid amplification test for the
qualitative detection of Chlamydia trachomatis (CT) and/or Neisseria gonorrhoeae
(NG) in patient specimens.
The following sample carrier can be used for CT/NG testing:
o PreservCyt® carrier with PreservCyt
®
primary containers
o 24-position sample carrier with primary cobas® PCR Media tubes or secondary
tubes
U
For more information about the test (e.g. minimum sample volumes), refer to the testspecific package insert.
About specimen types
WARNING
The following specimen types are supported:
Test type Specimen type Abbreviation Carrier used
CT/NG Swab - 24-position sample carrier
Urine - 24-position sample carrier

o PreservCyt® carrier

Supported specimen types may vary by region. Refer to the test-specific package insert for

Overview cobas® 4800 System
About workflow types CT/NG Test
About workflow types
Two workflow types are supported. The workflow type has to be selected at the start
of a new run.
Full workflow The full workflow covers sample preparation on the cobas x 480 instrument and
amplification and detection on the cobas z 480 analyzer.
Recovery workflow The recovery workflow allows you to recover aborted runs which were pipetted
correctly into the deepwell plate or microwell plate. For example, you drop the
microwell plate while transferring it to the analyzer.
You manually pipette residual eluate from the deepwell plate into the new microwell
plate and add new master mix reagent and Mn reagent.
To recover a run, the following criteria must be fulfilled:
o Instrument and analyzer are turned on and maintenance has been performed.
o A full workflow run has been performed and the samples successfully prepared.
o A full workflow run has been performed in the last 24 hours.
o A full workflow run has been aborted by a user (M2 flag) or the analyzer (Z1 flag).
About the test concept
The recovery workflow run is only validated to work with extract from an
instrument.
U
For stability of eluates, refer to the test-specific package insert.
Figure 1 Workflow and test type selection at the start of a new run
Tests are run in batches.
For more details about batch sizes, throughput, or mixed batch runs, refer to the test-
U
specific package insert.
About subtests
The analyzer can simultaneously detect signal from one or more detection channels,
which makes it possible to obtain more information from a single reaction. This
provides multiple subtests for each test type.
Subtests can be ordered for each sample individually using the sample editor.
U
For information about the sample editor, see Sample editor (p. 51)

CT/NG Test About reagents
The following subtests are available:
Main test type Subtests Results
CT/NG CT and NG in combination CT/NG
CT only CT
NG only NG
Table 4 Subtests
About reagents
Reagent kit sizes Individual reagent kits are available for the following run sizes:
o 10 runs with 24 samples (up to 22 patient specimens plus 2 controls)
o 10 runs with 96 samples (up to 94 patient specimens plus 2 controls)
NOTICE
Kit size
o Make sure that the kit size corresponds to the intended run size. Although not an
optimal use of reagents, a 96 kit size can be used for a 24 run.
o For the most efficient reagent utilization, it is advisable to maximize the number of
patient specimens processed within a run. Remaining reagents cannot be used later
for another run.
Reagent handling Some reagents are poured into reagent reservoirs and then placed onto their
dedicated positions on the reagent reservoir carriers.
Other reagents are ready to use. They are decapped and then placed onto their
dedicated positions on the reagent carrier.
Reagent expiry time zone offset
The reagent expiry date is based on the Coordinated Universal Time (UTC). The local time
CAUTION
for reagent expiry could be offset by plus or minus 12 hours, depending on the local time
zone relative to UTC.
r Check the reagent expiry date and consider that it is based on UTC.
U For instructions on handling and storage of reagents, refer to the test-specific package
insert.
Controls Two external controls (positive control and negative control) are provided in a
control kit. Controls are always processed on position A1 and B1 respectively of the
deepwell and microwell plates.
All controls are homogeneous and do not require vortexing or shaking prior to
loading on the instrument.
U
For instructions on handling and storage of controls, refer to the test-specific package
insert.
Controls are loaded on the reagent carrier not the sample carrier.
