Approaches to the prevention and diagnosis of IA.
| Strategy | Rationale | Laboratory diagnostic use |
| Prophylaxis | Prevention of infection using antifungal treatment and protective accommodation | None | Empiric | Early antifungal therapy in response to non-specific signs and symptoms | None (blood cultures are typically done to detect bacteremia and fungemia) | Preemptive | Antifungal therapy in response to early specific markers of IA | CT, GM, PCR, and BDG usually one or two markers triggering therapy | Targetted | Antifungal therapy of clearly defined cases of IA | All available investigations, using EORTC-MSG criteria |
