Clinical Microbiology · stage 4 of 5

Naming it, and testing what will treat it

Growth on a plate or a curve on an amplification run is not yet a result. By the end of this stage you can work an isolate through to a named organism by culture or molecular methods, decide what is pathogen and what is flora, produce and interpret susceptibility data, and recognise when the method or the instrument — not the patient — is what changed.

Work through these in order

1. 1Presumptive identification from the plate and a spot testPreparation and Testing CM-PT-18
2. 2Sorting true pathogens from background floraEvaluation and Interpretation CM-EI-1
3. 3Turning colonies on a plate into a reportable countPreparation and Testing CM-PT-27
4. 4Working a specimen through to a named organismPreparation and Testing CM-PT-6
5. 5Reading culture and cell results from blood and sterile fluidsEvaluation and Interpretation CM-EI-3
6. 6Handling specimens on their way to a molecular assayPreparation and Testing CM-PT-37
7. 7Getting nucleic acid out of a specimen intactPreparation and Testing CM-PT-12
8. 8Setting up amplification reactions without contaminating themPreparation and Testing CM-PT-14
9. 9Interpreting amplification data before a result is releasedPreparation and Testing CM-PT-31
10. 10Testing an isolate against the antimicrobials that matterPreparation and Testing CM-PT-39
11. 11Interpreting susceptibility testing before it is reportedEvaluation and Interpretation CM-EI-6
12. 12Judging commercial kit results and their limitsEvaluation and Interpretation CM-EI-13
13. 13Knowing where each method stops being reliablePreparation and Testing CM-PT-5
14. 14Reading the failure when equipment stops performingEquipment and Resources CM-ER-2
15. 15Telling random error apart from systematic errorQuality Assurance CM-QA-6
