Quality control troubleshooting
E140 The used Starrsed Control is out of date.
|
|
Use a new batch of Starrsed Control.
Check date/time settings.
|
E141 Result is out of range, the applicable values for the acceptable range depend on the user setting.
|
- Take a new Starrsed Control sample (normal samples will be finished).
- Check acceptable range in QC settings.
|
If results are continuously out of range but the statistics show identical/stable results, it should be considered to expand the acceptable assay range with QC Settings.
If this error persists check/clean instrument.
|
E142 The uncorrected result is out of range, but the corrected result is within range.
|
- Consider QC result as correct.
|
The mean value is assayed with temperature correction, result is correct.
Use general setting temperature correction (TCorr) ON.
|
E143 The uncorrected result is within range, but the corrected result is out of range.
|
- Consider QC result as not correct.
- Take a new Starrsed Control sample (normal samples will be finished).
|
Check acceptable range in QC settings.
If this error persists check/clean instrument.
Use general setting temperature correction (TCorr) ON.

Screen messages
QC result with ESR error
|
no ESR Result is given
|
- Check general ESR data, see ESR Error
- Check sample tube volume
- Take a new Starrsed Control sample
|
QC result with ESR warning
|
ESR Result is given
|
- Check general ESR data, general ESR Warnings
- Check Result at limit setting
|
|
This error indicates a general ESR error or a QC result error after QC sampling
|
- Take a new Starrsed Control sample, normal samples will be finished
- If this error persists check/clean instrument
|
Note: QC Error messages are only shown and stored on the Starrsed ST and not send to LIMS. QC result is given with the same general errors and warnings as a normal patient ESR-result.
General errors
Barcode is not accepted
|
Barcode cannot be read
Data is incorrect
|
|
QC sample is not accepted and not performed
|
Starrsed Control ID is not known in LIMS.
|
- Check barcode
- Link Starrsed Control ID to a Lab ID
|
Linked Lab ID is not accepted
|
A Lab-ID can be linked to one Starrsed Control ID
|
|
Deviating results
Systematic QC errors with a shift in control values (QC results are out of range)
|
The measured control values change abruptly up- or downwards.
Do not compare 30 minute method with 60 minute method result. The calculation method can give some deviation in the general QC results statistics.
|
- Check/clean instrument and perform a new QC sample
- If these errors persist perform maintenance step
- Compare only results from one batch.
- If Lab ID is used check the linked Starrsed Control ID. It is possible that a new batch is in use without changing to the new assayed mean value
|
Systematic QC errors with a trend in control values (QC results out of the range or nearly out of the range)
|
The measured control values change gradually upwards or downwards.
|
- Irregular or insufficient maintenance can cause unnecessary QC errors and ESR errors/warnings
