4 USE OF THE INSTRUMENT
4.1 WORKING LISTS
4.1.1 T HE JOB - LIST (J- LIST )
The operator who intends to perform a test run will normally have a list where each sample is
associated to one or more tests to be performed. The samples list can be on paper or programmed in
the memory of the Host Computer of the centralized system.
The Job List (J-list) is the list which associates all the sample codes to the test codes.
In the CHORUS system the sample must be transferred to a ready-to-use device for a specific test, in
order to be tested: the strip.
Each strip is provided with a bar code which specifies the type of test (test-code) it can be used for and a
numeric code which differentiates it from all the strips manufactured by DIESSE. The complete code
applied to the strip constitutes the strip-code.
Before conducting a session, it is possible to associate each sample code with the strip code of
the strip in which it is dispensed.
4.1.2 T HE C OUPLING -L IST (C-LIST)
The Coupling list (C-List) is the list which associates all the sample codes and the strip codes.
The instrument is designed to compile both a J-list and a C-list.
• To reduce error in the execution of the tests, to avoid performing tests on a sample which are not
requested, it is preferable that the J-list is compiled on the instrument automatically, via a
connection to the host computer of the centralized system.
4.1.3 T HE R UNNING - LIST (R- LIST )
The Running-list (R-list) is the list of the thirty positions in the carousel; the strip code identified in the
carousel and the associated patient code (if present) for each position is indicated.
It is compiled by the instrument using the identification procedure which foresees scanning of all the
positions on the tray using an internal barcode reader.
After scanning the carousel, two different cases may arise:
If a C-list has been saved, the patient code is attributed univocally to each of the strips identified,
according to the association present in the C-list.
If no C-list has been saved or if the strip code is not associated to any patient-code, the patient code
field will be filled automatically with a progressive number corresponding with the position number of
the sample holder tray.
The R-list produced in this way allows the result obtained with each strip to be associated to the
relative sample-code, but does not guarantee the lack of errors.
