Auto Serum Index/ORDAC
Auto ORDAC
Auto ORDAC permits the enabling or disabling of the automatic Overrange Detection and Correction
(ORDAC) function for specified chemistries (refer to the Synchron Clinical Systems
Chemistry
Information Manual and to the list of chemistries offering ORDAC in the Synchron Clinical Systems
Chemistry Reference Manual ). When a chemistry result exceeds the instrument analytical range and
Auto ORDAC is enabled, the sample automatically reruns with either:
• a smaller sample size or
•
an online sample dilution (chemistry dependent).
When Auto ORDAC for Ig-A and Haptoglobin is enabled, the URDAC feature is also enabled. Ig-A and
Haptoglobin URDAC is used to analyze samples with concentrations below the analytical range. In
this case, the system takes a larger sample volume.
(The manual ORDAC function in Sample Programming is used for samples which are known to
exceed the analytical range. Chemistries designated with manual ORDAC at the time of
programming are run at the ORDAC sample volume.)
From the
Setup
screen, select
1 Auto Serum Index/ORDAC
to enable or disable ORDAC. The default for
Auto ORDAC is
OFF
.
The
Automatic ORDAC
screen may be viewed at any time, however the system must be in Standby ,
Stopped, Startup, Instrument Down, or Homing to modify the ORDAC selection.
IMPORTANT
The analytical ranges for each analyte are system limits found in the respective CISs. These
are the ranges that Beckman Coulter has verified can be achieved by the system. There is no flagging
associated with values exceeding these limits.
The instrument printable ranges for each analyte are internal system limits. These ranges actually exceed
the analytical ranges by a certain limit. This allows for precision variations and still permits a result to print
even though it slightly exceeds the analytical range. Results outside this range are suppressed. The
suppressed results are flagged OIR HI or OIR LO (

Auto Serum Index
The Auto Serum Index function may apply to control material used in your lab. When enabled, Auto
Serum Index automatically analyzes every serum and plasma sample for the presence of hemolysis,
icterus and lipemia and numeric values (indices) for the relative concentrations are included in the
report.
The values are printed below the Special Calculations area of a patient report. The values are printed
with the test results for a control sample.
