Fungal Culture, Blood
Clinical Information: Due to the high mortality rate from fungemia, the expeditious detection and
identification of fungi from the patient's blood can have great diagnostic prognostic importance. Risk
factors for fungemia include, but are not limited to, extremes of age, immunosuppression, and those
individuals with burns or indwelling intravascular devices.
Useful For: Blood cultures are essential in the diagnosis and treatment of the etiologic agents of
fungemia. Fungal blood cultures should be requested on a select patient population that presents with
signs and symptoms of sepsis, especially fever of unknown origin.
Interpretation: Positive cultures are usually an indication of infection and are reported as soon as
detected. Correlation of culture results and the clinical situation is required for optimal patient
management. A final negative report is issued after 30 days of incubation.
Reference Values:
Negative
If positive, notification is made as soon as the positive culture is detected or identified.

Fungal Culture, Dermal
Clinical Information: Fungal infections of keratinized tissues (hair, skin, nails) can be caused by
dermatophytic fungi belonging to the genera Epidermophyton, Microsporum, and Trichophyton.
Opportunistic superficial infections resembling dermatophytoses may be caused by yeasts or by unrelated
filamentous fungi that are normally saprobes or plant pathogens. Dermatophytes are usually unable to
penetrate deeper tissues. Infection may range from mild to severe.
Useful For: Recovery and identification of dermatophyte fungi from hair, skin, and nail infection
specimens
Interpretation: Positive cultures are reported with organism identification. Negative reports are issued
