Test Catalog

Test ID: FGEN    
Fungal Culture, Routine

Useful For Suggests clinical disorders or settings where the test may be helpful

Diagnosing fungal infections from specimens other than blood, skin, hair, nails, and vagina (separate tests are available for these specimen sites)

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

When this test is ordered, the reflex tests may be performed at an additional charge.


See Meningitis/Encephalitis Panel Algorithm in Special Instructions.

Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Many fungi in the environment cause disease in immunocompromised human hosts. Accordingly, the range of potential pathogenic fungi has increased as the number of immunosuppressed individuals (eg, persons with AIDS, patients receiving chemotherapy or transplant rejection therapy) has increased. Isolation and identification of the infecting fungus in the clinical laboratory can help guide patient care.

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.


If positive, fungus will be identified.

Interpretation Provides information to assist in interpretation of the test results

Positive cultures of yeast and filamentous fungi are reported with the organism identification.


The clinician must determine whether or not the presence of an organism is significant. A final negative report is issued after 24 days of incubation.

Cautions Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

For optimal recovery of organisms, sufficient specimen should be transported within 24 hours of collection.


Fungi can be pathogens, colonizers, or contaminants. Correlation of the patient clinical condition with culture results is necessary.
