Deciding whether the number is real

The gate between a value the analyser produced and a value a clinician is allowed to see. You will be able to read control and calibration evidence, tell noise from drift, and reject a result that cannot be true no matter how cleanly it printed.

Work through these in order

1. 1Judging control and calibration data before results are releasedQuality Assurance CC-QA-5
2. 2Telling random scatter apart from a systematic driftQuality Assurance CC-QA-6
3. 3Keeping logs and control charts that stand up to an auditQuality Assurance CC-QA-4
4. 4Running external survey specimens as though they were patientsQuality Assurance CC-QA-1
5. 5Keeping bedside testing under laboratory oversightQuality Assurance CC-QA-2
6. 6Reading analyser output on blood and body fluid specimensEvaluation and Interpretation CC-EI-3
7. 7Spotting the result that cannot be trueEvaluation and Interpretation CC-EI-7
8. 8Deciding whether a blood gas result can standEvaluation and Interpretation CC-EI-12
9. 9Judging output from a purchased test kitEvaluation and Interpretation CC-EI-13
10. 10Producing and safeguarding digital imagesEquipment and Resources CC-ER-3
11. 11Working from a captured image rather than the specimen itselfEvaluation and Interpretation CC-EI-5
