Epic Test Code LAB242 Fungal Culture, Blood

Additional Codes

MML:FBL

Reporting Name

Fungal Culture, Blood

Useful For

Diagnosis and treatment of the etiologic agents of fungemia

Performing Laboratory

Mayo Clinic Laboratories in Rochester

Specimen Type

Whole blood


Specimen Required


Container/Tube:

Preferred: Green top (sodium or lithium heparin)

Acceptable: SPS

Specimen Volume: 4 mL

Pediatric Volume: 3 mL

Collection Instructions:

1. Send whole blood specimen in original tube. Do not aliquot.

2. SPS tubes are acceptable, but not preferred.

Note: SPS tubes must be clearly labeled as SPS. If label is obscured, sample may be cancelled, as ACD (also yellow top) is not an acceptable tube type.

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 42 days of incubation.
