Verifying Results
Results that satisfy lab quality standards are verified by the lab manager. If something is amiss, they may be retracted for re-testing. Clients browsing their Samples see their results for the first time after verification. The most important step in the Analysis life cycle, going public
Best Practice
... is to verify results on Worksheets in the context of the WS QC analyses and peers, including duplicates, Verification per worksheet overleaf
To verify Samples without inspecting individual analyses - for ISO compliance, Bika does not allow it - much additional navigation is required. It is avoided on worksheets
Verification
Analyses rule parent Samples
A Sample's status is always equal to the lowest status among all the individual child analyses it contains
Analyses individually advance to To be verified as results are submitted for them be analysts
Verifying results, either via worksheets or directly on the Sample as once the last analysis moves to verified, the Sample automatically follows suit and is ready to be Published
Clients see Verified results
Authorised Clients Contacts may track Sample progress on-line throughout, they for the first time see results after they are verified
In the next final step, the Sample's COA, Certificate of Analysis, will be published to them corresponding to their publication preferences
Verifying or Retracting Samples
To be Verified Sample list reflects all analysis requests with all results submitted and ready to be reviewed for verification
Bika does not allow blind verification of results from Sample lists, and no [Verify] button on the lists
The Verifier has to see the results on the Sample - open the Samples under consideration and inspect the results.
Retract
If some of the results require re-testing, select them and press the [Retract] button. The Analyses selected return to state Received. The Sample follows suit and demotes itself down from To be Verified
Verify
Similarly, results that are in order can be selected and promoted to Verified with the [Verify] button. The Analyses and parent Sample transition Verified state
An alert shown to users authorised as publishers to publish the Verifed Samples is ready for publication
Analysts don't verify own results
Qua ISO 17025. Unless explicitly configured not to, Bika and Senaite will not allow the same user to submit and verify results. The verify options are by default not available on Samples for the user who submitted its results
For small labs, or skeleton staff in emergencies, this feature can be disabled. The LIMS will display alerts along these results, and all activities remain traceable in the logs
Verification authorisation
Results verification is probably the most important action in analysis workflow. By default, only users authorised as labmanagers are entrusted with this
An additionally complimentary role, 'verifier' is available to assign to experienced analysts in addition to their standard analyst function
Some labs assign the verifier role to other staff only during peak periods and then remove it again
Verification per Worksheet
Where analyses were assigned to Worksheets and their results verified there, their states are promoted the Samples where they originate from
Looking up Analysis information. Log
At any time more information on a specific analysis can be looked up by clicking the blue information icon next to it. That brings up a pop-up with information on the Analysis' parent Analysis Service, the Method, Calculation and dependants
