Blue Rack:
Use this rack to analyze the reagent blank. This is used for calculating the reagent blank to
obtain the OD of the reagent without any sample. A reagent blank must be run with each
calibration. Place deionized water in the following position(s):
If the sample is serum: First position in the blue rack
If the sample is urine: Tenth position in the blue rack
If the sample is other: Fourth position in the blue rack
Yellow Rack:
This rack is used when creating the calibration curves. With ACAL tests, the calibration
curves are calculated from the standard solution concentration (known) and OD (obtained
from yellow rack analysis). Place standard solutions in the yellow rack in the order of
calibrator numbers that were set as parameters. For barcoded analysis, samples can be
placed in any order. Important: The last barcoded tube position that is defined in [Routine],
[Test Requisition], [Calibration] function key F6 Cal, must be placed in the highest numbered
position of the rack for barcoded analysis to work properly. The calibrator numbers
correspond to the sample positions (1 to 80) in the yellow rack. For example, 1 to 10 are
the cal. numbers and sample positions for the yellow rack of ID 1, and 11 to 20 are the cal.
numbers and sample positions for the yellow rack of rack ID 2. User defined positions for
serum, urine, and other calibrators are programmed in the [System Maintenance] screen.
Serum, urine, and other calibrators need to be placed in the correct yellow rack designated by
the rack ID and calibrator number.
Green Rack:
Use this rack to analyze quality control samples and barcoded quality control samples. For
barcoded analysis, samples can be placed in any order.
Important:
The last barcoded tube
position that is defined in [Routine], [Test Requisition], [QC] function key F6 QC, must be
placed in the highest numbered position of the rack for barcoded analysis to work properly.
For samples without barcodes, place the control samples in the green rack in the order of
the control numbers which were set as parameters. User defined positions for serum, urine,
and other quality controls are programmed in the [System Maintenance] screen. The control
numbers correspond to the sample positions (1 to 60) in the green rack. For example: 1 to 10
are the control numbers and sample positions for the green rack of ID 1, and 11 to 20 are the
control numbers and sample positions for the green rack of rack ID 2.
Orange Rack:
Use this rack for repeat-run analysis. In this system there are three methods of performing a
repeat run: a method which uses the STAT table, a method which uses the orange rack, and
a method which uses the white racks for an automatic repeat. Place sample containers in the
orange rack in the order of the repeat-run sample numbers for sequential analysis. Samples
with an ID can be placed in any order in the orange rack for repeat analysis.
Red Rack:
Use this rack for analyzing “emergency” samples. In this system there are two methods for
analyzing emergency samples: a method which uses the STAT table (priority samples), and
a method which uses the red rack (emergency samples). The red rack is used if the tests
in progress do not need to be interrupted for immediate results, but the sample needs to be
designated as an “emergency” and separated from the normal routine samples. The STAT
table is the fastest way to obtain results. There are no special restrictions on the order and
position for setting the sample containers. The sample numbers are automatically assigned
to the emergency samples in the order they are placed in the racks. For example, if samples
were set in rack IDs 1, 3 and 5 and analyzed, the assigned sample numbers (requisitioned with
an E prefix) are E001, E002 and E003 sequentially. If the sample containers are barcoded,
they can be placed in any position on the rack.
