HelpTest ID: FBL Fungal Culture, Blood
Reporting Name
Fungal Culture, BloodUseful For
Diagnosis and treatment of the etiologic agents of fungemia
Select patient population that presents with signs and symptoms of sepsis, especially fever of unknown origin
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.
Interpretation
Positive cultures of yeast and filamentous fungi are reported with the organism identification.
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.
