Diagnostic pathway

Use our interactive diagnostic pathway to discover the various diagnostic methods for IFDs

Several diagnostic approaches are available for IFDs

Conventional testing, which includes:

  • Culture
  • Direct microscopy
  • Histopathology

Non-conventional testing, which includes:

  • 1,3-β-D-glucan (BDG) biomarker detection
  • Mannan detection
  • Cryptococcal antigen testing
  • Galactomannan biomarker detection
  • Polymerase chain reaction (PCR), including pan-fungal and strain-specific PCR screening assays

Navigate your way through the diagnostic pathway of a patient with clinical signs of infection
