Clinical Chemistry · stage 5 of 6

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