Expert System
Platinum 6 Expert System
Automated marking and reflex testing for abnormal results
Platinum’s Expert System has been designed to save clinical time for those abnormal and rare samples that do not fit the normal profile. It allows the clinician to accurately determine the profile of a normal patient result through peak morphology, chemistry thresholds and other configurable settings.
Automatic identification
Samples are identified based on trace morphology and flagged by the software.
Reflex testing
Can automatically order an ID or IFE for flagged samples.
Configurable
You decide the rules under which the system operates, and how it responds.
Identification
Optimised for detection of small monoclonals.
External data
External chemistry data enables richer comparisons to be made.
Assistive technology
Streamline large workloads by focusing on investigation of abnormal results.
How it works
Expert System assigns a normal range, an uncharacteristic range and a definitively abnormal range. The user can configure what criteria are used for interpretation, including:
- Peak relative area
- Peak mathematical area (Absolute area)
- Peak height
- Peak position (Peak timings)
- Peak to peak ratios (relative area, mathematical area, height, position)
- LIMS downloaded chemistry results (e.g. IgG, IgA, IgM)
Results are then characterised using the configured criteria.
- Chemistry result sums (e.g. total Ig concentration)
- Peak sharpness
- Peak symmetry
- Combination formulas (e.g. relative area and height and sharpness as one criteria)
- Peak number
Examples
Normal
This trace has been characterised as normal as it falls within the configured parameters.
- The Expert System has been designed to reduce the number of normal results that have to be reviewed and to automatically deal with these.
- Normal results can be automatically sent to the LIMS queue or directly to the LIMS with a standard user configured comment assigned to the result.
Warning
This result has been characterised as a warning because the Beta 2 peak height and the chemistry value for IgA are slightly too high.
- The warning symbol informs the user that this result requires further investigation.
Abnormal
This result has been characterised as abnormal because both the height and relative area of the gamma peak are too high. The chemistry value for IgG is too high also.
- Expert System has the option to automatically perform immunotyping on abnormal results or prepare a gel tray for an immunofixation test on Helena Biosciences' SAS systems.
No. of bands
Expert System can also flag results with an incorrect number of peaks.
