Ranges

This section allows for the setting of ranges. Range options are reportable, reference and action. If a
reference and reportable range are set for an analyte, the system defines the area in between these as
abnormal. Setting ranges changes the appearance of the result screen on the instrument. Results that
fall in the reference range have no color or arrows associated with that result (in the result bubble).
Results that fall in the action range (critical range) will have a red tip and a solid arrow in the result
bubble. Arrow direction indicates if the result is out of range high or low. Results that fall outside of the
reference range, but not yet in the action range are abnormal. The result bubble will have a yellow tip
and hollow arrows indicating whether the result is high or low.
Range
Range opens to a list of analytes and the custom reportable range display. To begin editing:
1. Click on the + icon found in far left hand column.
2. Click on the Edit button.
3. To customize reference range(s), click on Add Range under the Reference Range section. This area
allows for ranges to be set based on sample type and/or age and/or sex. It is also possible to enter
only the low and high range independent of sample type, age, or sex.
• To make reference ranges sample type dependent, check the box in the Apply column and choose
the sample types applicable by clicking the down arrow in the Sample Type column. The sample
types displayed are either the default types or the types customized in the Sample Types section
of the Analyte Settings category.
• Reference ranges are age dependent by default. Up to six different sets of ranges can be age
dependent. Enter the low and high age limits and units; or, to disable age dependent reference
ranges, click to un-check the box in the Apply column. To use this feature, another customization
item must be added to the profile: Patient Settings > Patient Information and Positive Patient
Identification > Age and Sex
• To make reference ranges sex dependent, check the box in the Apply column and choose the sex
applicable by clicking the down arrow in the Sex column. To use this feature, another
customization item must be added to the profile: Patient Settings > Patient Information and
Positive Patient Identification > Age and Sex
To customize action range(s), click on Add Range under the Action Range section. The same structure is
in place for changing action range as it is for reference range.
