Identification of fungi

Why carry out identification?

  • Knowing which fungus is involved guides appropriate antifungal choice, dose and duration of therapy. It may also indicate the source of infection.
  • Additional or dual infections can often be identified (i.e. 3-5% of Candida bloodstream infections).
  • Severity of infection may be revealed from the extent of involvement on skin or scans, the number or load of organisms visible on microscopy or histology, or the strength of signal on antigen or PCR tests. These factors may assist in determining whether additional therapy should be added and in following response to therapy.
  • Assessing whether antifungal resistance is present, and whether an alternative antifungal agent is required.
