Overview
Virology clinical cases are structured laboratory-reasoning vignettes that integrate Module 3 evidences, specimen selection, antigen/NAAT/serology limits, and pathway-stage reporting, without antiviral selection or dosing.
Classification
| Case pattern | First move | Do not claim |
|---|---|---|
| Early flu Ag− | Frame limits; NAAT per local protocol | Influenza ruled out by Ag alone |
| Compromised CSF PCR | Validity / recollect per SOP | Definitive HSV exclusion |
| Reactive HBsAg | Confirmation hold per algorithm | Drug regimen from screen |
| Multiplex co-detection | Report both laboratory targets | Silent deletion of one detection |
Morphologic Features
Case cues are assay validity and pathway stage (controls, specimen integrity, screen vs confirm), not colony morphology.
Laboratory Characteristics
- Triage competing workups by risk (CSF STAT first)
- Document confirmation steps on reactive screens
- Use approved prelim comments only
- Separate analytical detection from clinical attribution
Reference Intervals
Case cutoffs, panel menus, reflex after antigen negatives, and blood-borne confirmation algorithms remain institutional, verify SOP when applying case patterns to real benches.
Clinical and Laboratory Significance
Capstone competence is sequenced decision-making that yields valid, method-aware, appropriately staged reports for clinical use.
Differential Considerations
In cases, differentiate STAT sterile-site needs from routine mucosal testing, method-limited negatives from true exclusions, and screen reactivity from confirmed pathway language before expanding claims.
Comparison Tables
Capstone checklist
| Question | Pass | Fail |
|---|---|---|
| Specimen valid? | Type, volume, transport OK | Reporting exclusion on bad CSF |
| Method fit? | Matches acute vs screen question | IgG answering “acute?” alone |
| Pathway stage? | Confirm done when required | Screen = final infection slogan |
| Therapy in report? | Evidence only | Drug/dose advice |
Classification Frameworks
Not applicable.
Laboratory Notes
- No treatment or dosing in case resolutions
- Hedge panels, confirmation algorithms, critical lists
- Module assessment follows integrated reasoning, not virus encyclopedia recall
